Cam-Action Lockable Door Latch Kit for Large Enclosed Trailers - Zinc-Plated Steel - PLR658-002

Average Customer Rating:  4.9 out of 5 stars   (20 Customer Reviews)

Steel cam-action door latch is ideal for large, professional-use trailers and similar applications. Bushings and bearings prevent wear on moving parts. Double-action handle protects against in-transit jarring. 1-5/16" Pipe not included.


Great product, just wished it came with instructions. No instructions where ever received, noting on the original manufactures website. So you guess, tack weld, fit into place, and check operation. Took more time than needed due to lack of instructions.

other than the instructions, This product is extreme heavy duty, and will last a lifetime of a trailer. The galvanizing is thick so corrosion is not something that will be an issue during its lifetime.

For my application I preloaded the welded assemblies with a door seal. Where the compression was 1/2 total thickness around the whole door. Works great and due to the length of Turning Arm it is a breeze for even the weakest person.

Another option I would like with this product is an Un-Coated version so it could be painted easier. With my application, I painted over the Galvanizing with the knowledge that the paint will chip off. But hey, a can of Rust-oleum is cheap and application is easy.

Note: these latches only work from the outside of the trailer. If you need to active, deactivate this latch from inside, then this one is not for you application.


The nicest, most helpful customer service ever! Products are high quality at a great price. Very thankful.


The cam latches where a great addition to my project.


This company has the best customer service I have ever seen. I work in the service industry and etrailer is top notch. Outstanding.
I will only shop with them when it comes to trailer parts!

Looks and works like the day I installed it. Sits in the weather 100 of the time. Never even had to adjust it. I just use it with the confidence it will last forever.

  • How Does the Pipe Attach to the Cam Lock Assembly on Polar 658-002?
    According to the manufacturer the pipe is the 1 inch schedule 40 pipe which means the inner diameter is 1 inch and the outer diameter is 1-5/16" so the attached video and the video are correct. I have also attached a photo from the manufacturer to show you the locations of the Anti-Rack Ring you requested. They will be located just under the top bearing bracket and just above the bottom bearing bracket. You will weld these rings to the pipe as well as the cams at each end and the handle....

  • Tips for Installing Cam-Action Lockable Door Latch Kit for Large Enclosed Trailers # PLR658-002
    Mock up the install of the # PLR658-002 and it'll become obvious which way to orientate the system. Trying to match the LH and the RH won't be as helpful as mocking everything up and test fitting it before installing it. Basically you'll weld the pipe to the handle and the keepers like you mentioned and then bolt on everything else to the door. There aren't install instructions available for this.

  • Height of Upper and Lower Cam Brackets of Polar Cam Action Door Latch Kit # PLR658-002
    The height of the Polar Cam Action Door Latch Kit # PLR658-002 brackets you referenced is 2 inches so you'd need 2 inches basically above and below the door for the brackets to fit.

  • Can Shims be Used to Install Cam-Action Lockable Door Latch Kit so it Sits Flush
    The great thing about the Cam-Action Lockable Door Latch Kit # PLR658-002 is that since it's a universal application you can definitely use shims for the cams so that everything is lined up correctly. When it comes to the strength of these, they are designed for large enclosed trailers which means they will definitely be up to the task of holding your doors in place, but they aren't really rated for a specific weight so I'm not sure how they would hold up to a horse leaning up against...

  • Cam Style Trailer Door Latch Recommendation For Limited Clearance Area for Brackets
    The big difference between the Cam Door Latch # PLR458-018 and the # PLR658-002 is the robustness of the pipe mount on the handle side. The # PLR658-002 is more for heavy duty applications and comes with bushings for the pipe to mount in. This requires a 1-5/16 inch diameter pipe and the other requires 3/4 inch diameter. That said, since you said you only have a space of 2-7/16 inches for the bottom bracket to fit you'd actually want the part # PLR258-002 instead as it has a smaller sized...
