Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - PLR9-A Review

Today we're going to be taking a look at the Hook and Keeper for enclosed trailers. A Hook and Keeper is used to hold doors and windows open on your enclosed trailer. One piece is mounted to the side of the trailer, typically this piece right here. The other is mounted to the door, which would typically be this piece right here. Once you open your door the hook goes into the keeper, and that's going to hold the door, or window, on your enclosed trailer in the open position. Nice secure connection point right there. Each piece is going to feature the pre-drilled mounting holes.

These are designed for a total of eight #10 mounting screws, those are not included, so they will need to be provided separately. The mount holes on the unit will accept 3/16" diameter hardware. The mount hole spacing, it's going to be the same for each piece, because that back plate measures the same. Center-on-center is about 1" separation, going this direction center-on-center is about 2 5/16" on center. Very nice aluminum construction, extremely lightweight design, but aluminum is strong and durable.

It's also going to do a great job at resisting rust and corrosion. The hook itself is going to measure about 4" long. That's measuring from the back of the plate to the furthest outpoint of the hook, you can see there, pretty close to 4". This piece right here, it's going to give us a measurement of 1 3/4" wide, with a height measurement of 3". Then this piece is going to measure the same. You can see that that backing plate is exactly the same on each piece.

This ones going to have an overall depth, that's how far it sticks out from the mounting surface of about 11/16" deep. This piece is going to have a depth with that hook down of about 3/8", and then again with it out about 4". That's going to do it for today's look at the Hook and Keeper for enclosed trailers. .

Ask the Experts about this Polar Hardware Enclosed Trailer Parts

  • Installing Hook and Keeper for Trailer Door
    As you may expect, it would not be possible for me to tell you exactly what somebody else was talking about, and I would only be able to tell you about the products we carry. For example, if you use the Hook and Keeper # PLR9-A you would install either side with eight #10 mounting screws. I have added a link to a video review of this part for you to check out.

  • Door Keepers for Enclosed Trailer Doors
    We only have the door keepers available in 4 inch. We have the stainless steel # PLR9-SS, Aluminum # PLR9-A, and Zinc # 383400. We also have some plunger and socket and stem and socket options, but these have less space. I've linked the page to further assist.

  • Solution to Hold Swinging Trailer Doors Open
    What we have is a Hook and Keepr # PLR9-SS in stainless steel, # PLR9-A in aluminum, and # 383400 zinc plated. These are used to hold trailer doors open similarly to how you are using a hook and chain. One piece is conneted to the side of the trailer and the other is connected to the door. The hook slides inside of the keeper when open to hold the door in place.
