Video Transcript for Comprehensive Review: T-Style Hook and Keeper Door Holder for Trailer Rear or Side Door

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. .

Good price and quality

These make great Dutch door keepers on the barn!



by:

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!

The door keeper is working great - no worry about wind blowing door shut



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!



by:

I will say this was a very pleasant
transaction,
I was well informed and updated with the shipping information
and notified when items were shipped and everything arrived in two days. I
highly recommend etrailer to anyone requiring your products and I will
definitely be using etrailer in the future for my trailer and RV needs.



by:

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

These replaced the old rubber ones. I love these. They work great on the horse trailer.

The product fits and works perfect !! They are a whole lot better than the ones that came with the trailer. Took about 5min. to install.

This little gadget is just what I needed. Easy to install and works perfectly to hold my enclosed trailer door open.



by:

My original door stops were broken so ordered these. Looks just like original ones and works great



by:

Screws too long and snap easily, otherwise a great product. I pop-riveted the pieces to the trailer, no other issues.



by:

Works ok. Tip. Put the door side on first. It's nice to be able to keep the door open.



by:

Keeper was flush mounted and did not line up with hook correctly. I had to use washers to bump out one side to make it work, but it does work.



by:

Great Product, etrailer's customer service is excellent

  • 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.

  • 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.

  • 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.
