The hinges and locking mechanism is being used on a home built camp trailer for double doors on the back covering the kitchen. It looks like they will work nicely for the job. Thanks. Couldn’t be happier.

Strap hinges and closer mechanism are working perfectly on the 10’ home built camp trailer. I couldn’t be happier. I show all my friends and sing your praises

My only issue with the product is that the manufacturer has failed to disclose what diameter pipe is required that the handle and ends weld to, if that information were there, it's a 5 star product. To anyone that reads this, 3/4" Black gas pipe required

This lock set is still working very well, originally I think it was designed to be able to lock both top and bottom of the doors, I redesigned my doors so that they lock on the bottom only and the top helps keep the sides from getting sprung from pressure on the sides pushing out, all parts still work like the day they were installed and the lock is tight enough the doors dont rattle while towing

I purchased two of the Universal Cam-Door Lock for Enclosed Trailers - 38320. I used them to close barn doors that are 80" by 80" each. The cam -Door Lock works great for these doors. All the parts are very heavy duty. The Cam-Door Locks closes the doors very firmly against the frame from top to bottom, keeping the doors even and level. I have also used this kit to close doors on a wood drying kiln where the doors have to tightly seal. Again, they work great to apply the needed amount of closing pressure to engage the weather seals. This kit is a good buy where you need to close doors with firm pressure.

The Cam Door Lock works great. I am still very pleased with the product. I have recommended it to a number of people.

We have used the Cam-Lock
for three generations of our Rapid Deployment Units (RDU Trailers). These RDUs are shipped all over the world and as often as not are deployed into challenging environments. The Cam-Lock system proved to be a rugged and reliable way to protect and secure the hatches over the battery compartments.



This product was great in the creation of our Honey Warmer. The CAM LOCK has created a locking door system on our insulated doors that will keep a tight seal to hold in the heat we need to warm our honey for processing.


Great product! Purchased this to make custom rear doors for a Food Truck, and this works exactly as described and like we need it to. This product requires a separate bar, for which we used stainless steel conduit, as well as welding experience to put it all together. I had to have help with the welding and the overall assembly, which I why I'm giving it 4 stars instead of 5 - not something the general jack-of-most-trades can use, but overall I'm very satisfied with this product, and would definitely recommend it if you have the skills or have access to the skills needed to put it on!


As a class project our students were designing and building a canoe hauling trailer for a local outreach camp. This kit worked great and looks great too.


Have not installed the products yet.
Website illustrated very good product info.
2. Very satisfied with shipping methods and quickness for delivery, even though it was standard shipping.
3. Would rate your company in the top (10) for overall performance that we have experienced in our (40) years of business.
4. Joe was very helpful.

Very Good

Received order in a timely manner with the product quality as expected. Have ordered a couple times from E-trailer and always get fast delivery and competitive prices.


I ordered 2 of these for a horse trailer on a Monday morning at 11am and these people had them at my door in less than 24 hours and I know I picked standard shipping. The products were just what I needed and are made of high quality steel. Highly recommend!!


This works great. I bought a 14 foot enclosed trailer, with a side swing door. I turned it into a drop door, but I needed hardware for the locking system. Then I found the latch system on Easy to install, and the video tells you everything you need to know as well. Took me literally 10 minutes to put everything on. Great, great, great!!!


I bought a used Pace trailer with a broken lock latch. Could not find anyone in Northern Michigan to fix it. Went on line at Pace, received the part in a few days. Very pleased. A lot more parts in the package than I needed but the price was still great.

The parts were exactly as described and working well.

I think the cam lock assemblies are jut the ticket. They are just what I needed for the trailer/toy hauler I built. I do wonder why the great big box for two little boxes? LOL

I will definately think of ya'll when I need parts in the future. I do have one question. Do you carry add-on electric barkes that would fit on a common car hauling flatbed 16' trailer?


Hard to believe its been a year since I bought these. I still have not used them to made the door closers. It will happen this spring for sure. As for the kit itself, it was complete and I think the material strong enough to do the job.


This Product saved us quite a bit of problems and would recommend it to anyone.
Service was outstanding and was shipped in a timely manner even to Canada.


4 Star, this was a one time purchase to fit our need at the time. I have nothing negative to say about etrailer


The trailer door hinge lock works great. The only complaint I had was the ends don't fit the pipe very snug so i drilled and tapped some holes and added set screws.


great kit to replace your worn out latch. obviously it doesnt come with the cross bar and this is NOT something you can just snap together in your driveway, well thats unless your home garage is a mini shop!
simple to install works great, would recommend to a friend for sure.

Thanks Etrailer!


A great product. Installed it on a side door of a Wells Cargo trailer to provide some security while the trailer is out of the lot. I would definitely buy this product again. Sorry, I didn't take any pictures and the trailer is on the road already.


Everything is well constructed however i will not be able to use them as the add did not have enough info and they will not fit the trailer i have. I ordered 3 sets and the add states will work on any enclosed trailer however they will not fit in place of the old ones as the bolt holes do not line up. I was only replacing as mine were rusted and i do not want to drill holes in a trailer that is only 3 years old just because the old ones are rusted.


All products worked great. Price was good. Fast delivery kept my project moving on schedule. Next project, will be the first place I look for parts.


Good quality product. Quick ship!


Great product. After someone cut the entire latch off of my trailer these parts put it back the way it was!!!


It works great... provides for a tight and secure (big rig) type of fastener for my camping/utility trailer.


Great product, just wish I could have used carriage bolts instead of hex bolts when installing.
