Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - PLR158 Review

Today we're going to be taking a look at the Polar hardware universal cam door lock for enclosed trailers. This plain finish cam lock is for all van bodies, trucks, and trailers. It's ideal for side door and rear door enclosed cargo trailer applications. The lock can be installed on flush to 3/4" offset doors. I do have it laid out for you in the way that it would install. Obviously on a table it is more compact, but this does give me an idea of how the unit would install to a trailer door application. It's made from a strong, durable steel construction.

It's going to feature a bridge type keeper that prevents accidental opening and ensures safe locking action. The positive double action handle gives dual protection against in transit jarring. This handle is designed to weld onto a pipe which eliminates cutting the pipe. It's designed to be used with a 3/4" inner diameter pipe which is not supplied, so that does need to be provided separately. You'll see here that this rotates up and out of the way. Here's your handle that allows to open.

Comes back down, and then you can install a clip or a lock on there. This will accept a shackle diameter up to 1/2". The unit's also going to feature all the other components, the handle has a nice coated end on it for an easy grip design. It's going to have the 3/16" thick bearing covers. It's a nice durable design as well.

Then the bearings right here go into the end of the 3/4" inner diameter pipe, and then they rotate under for a nice secure closure and security. When it comes to the keeper right here, that's going to give us a width of 2". Then the overall length of the keeper, that's going to measure 5" long. When it comes to the mount hole diameter for the pipe brackets and holders, these are 13/32" when it comes to the diameter, so these holes will accept 3/8" diameter hardware. The pipe brackets are a 2 piece construction. Again, everything is a steel construction, nice durable design.

Then this handle's going to measure 13 3/4" long. That's going to do it for today's look at the Polar hardware universal cam door lock for enclosed trailers.

I have not done a review before; however the shipping and the quality of the items is unbelievable it force me to make the time. I am not making this statement based on just one order but on three over the last year. So with this statement etrailer.com is now the first place that we look. The promptness of the shipping is fantastic. On a scale from 1 to 10 on the shipping & quality they both are a 10! As for the price, they are very very good, you may save a buck or two but the quality is well worth every cent and when towing equipment id rather be safe than sorry!!!! 344887

Ask the Experts about this Polar Hardware Enclosed Trailer Parts

  • How Does Handle of the Cam-Action Lockable Door Latch Kit # PLR158 Attach to Bar
    The keeper and lug of the part # PLR158 are the two pieces that mesh together to hold the door shut like you mentioned. The handle of this gets welded to the bar. I attached a review video for this for you to check out as well.

  • Replacement Cam Door Hasp for Enclosed Trailer
    Sounds like you are looking for the part # PLR158 which is basically the cam door latch that you mentioned without the bar. Or if you need just the hasp part we have the # 158-101.

  • Replacement Parts for Rear Door on 2006 CM Horse Trailer
    It sounds like you are looking for replacement parts for a 2-point cam-door lock. We have many such kits, shown on the linked page, both kits that include the pipe like # 305736 and kits that do not, such as Universal Cam-Door Lock # PLR158. For this you would need to re-use your pipe (so long as it is 3/4-inch inner diameter) or supply a new one. For such an installation you will need to weld the handle to the pipe.

  • Recommended Side-Door Lock Assembly For Enclosed Trailer With 24-Inch Gate
    The handle and lock I recommend for your trailer is part # PLR3057-SS. This is a stainless steel lock. This system does not come with the required 3/4-inch pipe but you would be able to use a 24-inch length of pipe to work for your trailer. A couple other kits you may want to check out are part # PLR158 which attaches to a 3/4 inch pipe, or if you want ot use a 1-inch pipe you can check out part # 383200. The kits that you mentioned like part # 305736 that come with the pipe...

  • Trailer Lock for Toy Hauler Door
    While we do not have any specific replacement parts we do have some options but you will need to replace the latch system (unfortunately the second picture you mentioned did not come through). For example, you may be able to use the 55" Lock Side-Door Bar Lock Assembly # 3057-55 or the Cam-Action Lockable Door Latch Kit # PLR158. I have added links to video reviews of these locks for you to take a look at as well as a link to our entire selection of locks so you can see if there is...

  • Mounting Hole Spacing Between Cam Door Lock # 3057-55 and Existing Door Lock Don't Match Up
    Across different brands and sizes of bar lock assemblies, such as # 3057-55, I am certain there is more than one possible bolt pattern. What I recommend is a version that does not come with a bar such as # PLR158 so you can provide your own bar at the appropriate length. Otherwise you could line up either the top set of holes or bottom set of holes on the door and then drill new ones for the other bracket for # 3057-55.

  • Material of Polar Universal Cam-Door Lock for Enclosed Trailers with 2 Inch Keeper
    The Polar # PLR158 with 2 inch keeper is made of steel construction. The # PLR158 takes 3/4 inch I.D. sized pipe. If you prefer a 1 inch keeper the Polar # 383200 is also made of steel construction and takes a 3/4 inch I.D. sized pipe.
