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. .

I bought this to replace my Escape 17B travel trailer’s original plastic hook that became brittle and then broke several years ago. Easily installed using a cheap rivet gun I bought from Walmart. The hook’s and keeper’s lower two holes of the four holes for riveting did not exactly match the original holes of the broken plastic so I had to drill a little, but it’s not a problem. It looks so good on my fiberglass travel trailer. Excellent product from etrailer.com. Thanks a lot etrailer!

It’s still nice and shiny.

We have a 1957 Jewel travel trailer and this replaced the original plastic door holder. Worked like a charm.



by:

Like most any lock they can be a little temperamental after being out in weather a while, but a shot of lock lube or WD40 takes care of that. "Training the lock to your given key is a breeze, and I definitely like the convenience of not having to try and recall which key is needed to use them!

I recently bought a used toyhauler that needed a latch type door holder (this thing)—works perfectly. But even more, etrailer is now my go-to source for all trailer parts. This is my 2nd or 3rd order. Each time my experience ordering online has been excellent.

  • 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.

  • 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.

  • 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.

  • Is the Hook and Keeper for Enclosed Trailer Door PLR9-A Spring Loaded
    The Hook and Keeper for Enclosed Trailer Door part # PLR9-A are not spring loaded. That said, we do have spring loaded options like the 45-Degree T-Style Hook and Keeper Door Holder for Enclosed Trailer part # 37211765. We don't have any straight spring loaded hook and keepers unfortunately.

  • Recommended Replacement Latch And Holder For A 2016 Fleetwood Bounder
    I took a look at those latches on your 2016 Fleetwood Bounder and was not able to find anything, unfortunately. With that being said, the best we can offer is for a completely different replacement. I know this probably is not ideal, however if you're interested the closest I was able to find is the: -T-Style Hook and Keeper Door Holder for Trailer Rear or Side Door # PLR9-A. This door holder uses a low-profile hook and keeper to keep your door open while loading and unloading. The hook...
