    Installed 4 of these locks on my travel trailer today. I put the key in the slot and it works great! The 751 lock was wiggle and jiggle and put the key in backwards and try again. These seem bulletproof and worth the cost.

    Shipping was fast up here to north west Canada. Once I figured out that it was “just” to short, with the old finger pull (which I did need anyway:), it fit great. Then it’s a balance between to tight and the tube key won’t turn all the way, and “just” tight enough. If one stops think replacement cost, for all that’s in a trailers front pass-through hatch. Gives me a better piece of mind.

    Prevented a break in
    I have been using the tubular cam locks for about 3 years. I had a thumb lock on one side of the hatch and your lock on the other. The would be thief attempted to pull open the hatch but could not make it through your lock. I have now ordered a lock for both sides.

      Glad to hear you’re happy with your purchase and thank you for the feedback.

  4. Keith Bush

    by far the best customer support I have had! They support was beyond exceptional, i made mistakes, and they were right there to help me fix it, and now the trailer is all set. Thank you so much for going above and beyond!

    Can’t say enough about how pleased I am with my order from ILH – I used their measurement guide and ordered 10 cam locks to replace my RV’s OEM ch751 locks – they arrived within the week. The packaging of the equipment was great with different components coming in separate sealed sections of a heavy packing plastic sheet. Everything was organized and the directions walked me through the first installation – after that the rest fell into place pretty quickly. Totally happy with the product, the finish and the end result. Woudl certainly buy from them again but I”m out of locks to replace!

    I just purchased 9 of the “CH751” replacement tubular cam locks and installed them on my travel trailer. I found the locks to be of high quality and excellent function. They are more expensive than sets of tubular locks you can buy on Amazon, but the high quality of the locks and knowing that it is nearly impossible that anyone else in a campground will have the same keyed locks is reassuring. I used “Hillman Machine Bushings 3/4″x1-1/4″ x 18ga” I bought at Lowes to function as backing and front support. These bushings are about $.89 for two and are thinner than normal washers but still very strong. The result on the outside front was a nice round and flush look surrounding the lock and the backer one on the inside gave great support also. This should also prevent most hammer throughs by a thief that simply pounds the lock through the flimsy door with a hammer and punch to gain access. If you want to upgrade your locks away from the CH751 mess, buy these locks!

    Didn’t work for me. When the retaining nut met resistance as I slowly tightened it, the nut would ride over the cylinder threads. I could never get the nut to firmly tighten. I tried two different cylinders/nuts with the same results. It seemed like the cylinder threads were too shallow and the nut fit too loosely. I returned them. Staff was great with communication and processed the return promptly.

    • ch751temp

      Thank you for the feedback David. Unfortunately we had a batch of bad cylinder housings that we thought we had removed from our shelves. We aplogize for the inconvenience. As always our focus is customer satisfaction.

  8. Sausha Miller

    The customer service is absolutely amazing. I measured wrong and was directed to the sells department. They were able to do an exchange, that was a very easy process. They were even able to help me find a solution to get my slam latch keyed differently. Definitely will recommend ILH!

  9. Stephen Van Lowe (verified owner)

    I love my new tubular cam locks. I now have the piece of mind knowing that no one can snoop around in the storage compartment of my new travel trailer (even though there isnt anything super important in there.) Installation was easy, I did have a little problem with one of the nuts that holds the whole lock in. It didn’t want to thread on the barrel. But I was finally able to get it. Other than that, I’m very pleased with my purchase and would order again from Industrial Lock.

  10. Michael V (verified owner)

    Bought a set of the tubular ch751 replacement locks (round key type that are higher security) for my service truck and the compartment door on my business use travel trailer…my locks came very quickly and were impressively well packaged.This was my first time buying from Industrial lock and Hardware and it won”t be my last…locks are very high quality and give me much more confidence that my tools and merchandise are better protected from theft. The folks at this company seem to really care about helping their customers make the right choices with their products —I strongly recommend that you give them a try for any of your lock oriented needs…you will be as happy with your purchase as I was for sure!

  11. Skip (verified owner)

    These are really nice, look good and work well. I’m very please with these. Easy to measure. Easy to order. Fast shipping. Great packaging.

    Installation would have been easy if someone had given me the following advice:
    Be careful not to over-tighten the nut that holds the lock arm. Easy to strip.
    Be careful with the cam governor. Its very likely that it will fall off during installation. Be sure its put back on in the right direction. Also, don’t lose it…they’re small and critical for operation.
    Very happy with the backing plate.
    Satisfied but not thrilled with the dust cover.

  12. Rory

    I’m from Canada and couldn’t get them sent to my home, but I used a shipping outlet in a bordertown in the US and got 4 of them with dust covers that way. Installed them with my 10 year old rig before heading to Florida. I’m very impressed with them and I’m going to order a couple more for the saddlebags on my motorcycle. Now if only they would ship to Canada…

    • ch751temp

      Thank you for the positive feedback. We’re glad you are happy with your locks. We now offer shipping to Canada.

  13. Bill Gerhardt

    I replaced my original locks on my two compartments with these locks. The entire process from ordering the locks to their installation couldn’t have been easier. Just follow the easy instructions, take 3 simple measurements and you’re all set. I ordered these locks on Dec 27th and they were delivered and installed on the 31st. Everything was included to make this process simple. Thank you ILH for doing what you say you’re going to do, and setting the standard for customer service.

  14. Ike R

    It really give me peace of mind knowing that with these tubular locks I don’t have the same key as everyone else. Plus these locks look really nice on my forest river. I would really recommend getting the dust covers as well.

    I wanted to commend you on your service and product. Sure, there was a problem but you solved it in two shakes – Well Done! And, I wanted to compliment Vallerie. I spoke to her both times I called and she was very pleasant, knowledgeable, and helpful…

    P.S. We head out with our new locks on Monday – Thank you for getting them to us so quickly! 🙂

  16. Jim (verified owner)

    Most likely will order for our Class A

    Like what I hear and see.

    I’m back for more!

    I replaced all of the original locks on my RV with tubular cam locks 18 months ago. The new ones are of high quality and are holding up to weather and use. I’m adding some new fixtures to the outside of the RV so I’m ordering more locks. You can’t go wrong with these. Customer service from ILH is outstanding. They answer their phone and call back as promised .

  18. Bryce (verified owner)

    High quality product

    Great fit, looks good. I recommend this product as a high quality replacement for the stock locks. Installed on a Lance truck camper for my generator and accessory compartments.

  19. Dewey (verified owner)

    Love them!

    I bought these a while back and installed them in my RV with no problems. I was having a problem with someone opening up my black water tank while I was camping with the family (My Son-in-Law’s idea of humor). With these locks I’ve had no problems.

    I would buy these again in a heart beat.

  20. Sut (verified owner)

    30 years of the same lock. Time for a change.

    The locks on our 1990 Kit were ch751, our 2010 Keystone used CH751, our new 2017 Palomino uses CH751. We purchased and installed the cam locks on our Keystone and had no trouble with them. We are in the process of setting up our new Palomino and WILL be ordering a set of these fine locks. Thanks, So Fred comes over and says “I came to borrow your drill yesterday when you were not home and you have some kind of funny locks on your compartments. I just went three rigs over to borrow Jerry’s. He was not home so I just used my CH751 keys to get it. Now I need to get it back before he gets home”. LOL

    Great Locks

    You have the best locks and the best information on these locks. Thank you!

  22. Rvduck (verified owner)

    Excellent upgrade for my new camper.

    I just installed 7 of these locks on the outside compartments of my new camper. They look great and work so much better than the cheap CH751 locks that came on my expensive new RV. I have owned RVs for 42 years and I sold RVs for a year and have always disliked the CH751 locks that come on most RVs.. The fact that most units out there have the same key is a real security concern but to me the best part of these new locks is how easy they are to use.

  23. L.M. Albuquerque NM (verified owner)

    I really love the way it was packaged and so well organized!

    I will install the locks in a week before our trip for the 4th. I thought you would like on feedback on your products packaging. I will definitely order from your company again. I was thoroughly impressed with your whole ordering process!

  24. Mello Mike (verified owner)

    Impressed with the packaging

    I have to say that I was impressed with company’s packaging. It came via USPS Priority Mail with all hardware professionally sealed in a compartmentalized plastic, see-through bag. This effort shows attention to detail with the order and is something you don’t typically see nowadays. It’s pretty refreshing…

    Great level of service

    I wish there were more companies out there with this level of service. Amazon for example, has left a bad taste in our mouths as of late when it comes to service. We’d rather purchase from independent vendors like ILH (Industrial Lock & Hardware).

  26. Jerry – Port Orchard WA (verified owner)

    Thanks for the info

    We just bought a new trailer and found that the cargo keys from our 20-year-old trade-in fit. That’s when i went on-line and confirmed that the same key fits just about every RV out there and that anybody with $5 can buy a pair of keys on-line. Nice. This led to me to you guys.

  27. Bryan – Sebastopol CA (verified owner)

    Excellent Customer Service

    I have completed literally thousands of internet transactions and who-knows-how-many other retail purchases over the last 50+ years and I have never experienced the level of excellent customer service extended to me by Industrial Lock & Hardware. This is a company who understands their customers

  28. P.M. – Winthrop WA (verified owner)

    This is what I call customer service!!

    Do you know how rare it is to be contacted by customer service rather than have to dig through a website to find an email, fill out a stupid form, and pray for a reply in my lifetime?.

    Excellent Guidance and Service

    I wanted to take a moment to thank you for the excellent guidance and service I have received in ordering a set of your locks for my RV. Your products are of the highest quality and every aspect of dealing with your company has been a pleasure. Thanks and keep up the good work
