The initial part I received was broken. I sent an email expressing concern and just received a generic response. It appears that my 1st email went to the wrong address. I received a follow up email and etrailer sent a replacement with no questions asked.
I replaced an existing door keeper and this one matched the holes perfectly. I don't know if it is alignment or the angle of the door but sometimes the hook does not want to drop right into the keeper.
The part works and I did get great support from etrailer once I got to the right person.

tracking site. I have a V-nose trailer so I had to do a simple modification to the hook in order to mount the latch to the trailer. Rivets were used to secure the hardware to the trailer. Excellent product and service.

Holds door open during loading. Just what I wanted. Extra bonus, the moving part of the latch is spring loaded wo it stays flat when not in use and it does not rattle, or get in the way.

Perfect fit to replace my rusted 12 year old door hold. I had to bend the arm to match the bend in my OEM parts.

After a year, its holding up perfect...totally negates the disadvantages of a outswinging door....

by: Bob S 09/24/2014

Received the trailer door hooks & keepers. Everything went on without a hitch. My entrance door and escape door will now stay open. The latches are built well and should last a long time. I placed clear stone guard under the hook so it will not mark the trailer sides while traveling down the road.

They work great. Have not had any problems.

Good and sturdy as I was hoping it would be. I painted it white to match siding on trailer where I installed it to make it more appealing. It replaced a plastic OEM type that cracked too easily. Yep it did what I wanted it to do.

This door stop really does the trick, good heavy duty metal construction. Replaces the cheap plastic one that was on the trailer in the first place. Would buy from again!

Great! Holds strong, very durable

by: Chris G. 11/03/2015

This is my first time ordering parts from online and I must say this was a great experience. I have had issues getting parts from other businesses in the past when picking up parts in person. So to have this run so smoothly is quite nice. The site was easy to navigate even for someone that is still new to computers. Everything is very well described and has photo's of the parts if there is a question. The cost for both parts I ordered were very nice I thought and then to top it off they showed up right on time like they claimed they would. The quality of the parts is top of the line and after this experience I can say for sure I will be coming back for any of the parts I need in the future. Thank you very much

the parts I ordered are still holding up and in working order. Very pleased with service and purchase still. i just havent had anything else brake lately to replace.

Bought this to replace the original one that fell apart on my 24' Haulmark car hauler. This one is better built and has a little bit larger mounting bracket on the arm mount side, which also allowed me to anchor it better. The receiver end of my old one was still mounted on the door so I reused that part. Don't think this one will fall apart anytime soon.

by: Cindy 10/22/2016 One Year Later

I put this door hook and keeper on my horse trailer that has one heavy rear door in hopes that it would hold it open in the breezy conditions here. Unfortunately, the first time I tried it out, the wind took the trailer door and blew it completely open, crushing the keeper. I tried to pry it out with a screwdriver but it's pretty much unusable. It would probably work with a lighter, smaller door.

by: John 12/31/2019

I bought two double wheel covers and they went right on without a fight.
I bought a couple of baggage door catches as the old were sun beaten and cracked. they went on using the same screw holes, perfect match. I bought a steel version of the old plastic hook and keeper door catch, which the sun had rotted. the bolt holes lined up tighter then the old holes which were stripped. The screws are not stripped now. I bought the Camco cam lock to replace the missing one on my heater door. It works like brand new. I haven't mounted the door lock yet.

by: Sebastian 11/29/2016

I was looking for a product to keep the side door open, while I am loading-unloading my enclosed trailer. It perfectly meets my need on a very reasonable price. The only additional work I had with it to make it fit perfectly was to bend the latch , so it moves easily in the lock. I can definitely recommend this product.

by: Eric 10/24/2019

These door keepers are exactly what I ordered. They are cad plated and I expect them to last a long time. The hole pattern matches the old crazed plastic ones, so that will save me some time.

So far, they are working out just fine. I wish that you offered a little longer version though.

These door latches are much more substantial than the cheap plastic variety that came as standard equipment on my Utility Trailer.

Now that a year has passed, the latches are holding-up just as good as the first day I installed them.

by: Lee Petersen 05/26/2012

with the Trailer Door Hook & Keeper # 383400. It works great in any kind of wind. The same type of latch came standard on another trailer I own and the only difference was a spring that keeps the latch from bouncing when not in use. Very good price and easy to install with pop rivets.

by: Dave 02/21/2020 One Year Later

I haven't yet installed it but the price was right and the quality of the latch is what you expect from etrailer. Fast shipping and great customer service when dealing with etrailer, and they have it all.

by: James R 03/12/2017 One Year Later

thanks for the follow-up. kind of drug my feet but finally got my door bar lock and latch installed everything worked well. When the needs arise, I will be ordering from you again...

by: C. Thompson 04/27/2012

Good quality, good simple packaging. Would have helped to have attaching hardware included, but did not detract to clean existing screws up with my urging wheel. Very satisfied overall. Satisfied with the ventline roof vent. Mounting was an exact match to the unknown brand of vent that I replaced. Great job etrailer.com.

by: Chris 09/07/2014

I was impressed with the quality and service from etrailer. I have bought several items for our cargo conversion and they have all exceeded my expectations.

Quality items, great value, fair price and friendly service... what more can you ask for?

Thanks etrailer!

by: Mike B. 05/17/2016

I just finished installing the door latches I purchased. They were installed on a 1976 Fairmont MT-19 railroad motorcar. The rear side panels of the cab were originally bolted to the frame making them stationary. This made the cab pretty cramped and on hot days, provided limit air circulation. I remounted the panel on a long piano hinge to allow the panels to be opened like a door and swung back towards the rear of the cab. The latches are used to hold the panels open in nice weather.
The latches work beautifully and look much more professional than using bungee cords to hold the "doors" open. I have some of your spring bolts on order that will be used for locking to panels in the closed position. Thank you!

Recommended Door Holder for Fender Mounting
The Plastic Stem and Rubber Socket Door Holder - 2" Long Stem # DH39R can be installed onto your fender if desired to allow your door to be secured open. You can alternatively use a Hook and Keeper for Enclosed Trailer Door # 383400 in another location like mounted to the fender to give you a similar option. There is not an option we carry that is long enough to allow connection to the main trailer wall when the fender is making contact with the door.

Holding Trailer Doors Open Using Plungers or Hook and Keeper Holders
Regarding the man door and the awning, is there any way that you can attach the plunger style holder, # DH605, to the support are for the awning that is causing the interference? Otherwise, you could use something like the hook and keeper, # 383400. If they were placed near the door hinges you could probably configure it to hold the door open where it will not interfere or shut. The same thing for the rear barn doors. The stress on the door keepers would be greater the closer they are...

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.

Replacement Latch Part for 1994 Fleetwood Bounder Motorhome
RV makers do not maintain any specs on smaller items like door hardware they install on their motorhomes so we have no way to look that up for you. Since I don't know which particular type of latch you need to find a replacement part you can use the linked pages that display the various door parts we offer, such as Hook and Keeper # 383400. If you like you can email me your photos of the door/compartment for which you need the latch part and I will be glad to help you find the right item.

Installing Trailer Door Hook and Keeper # 383400
You will usually see the hook portion mounted on the trailer door, with the keeper connected to the side of the trailer, but there is no reason why you could not install it the other way, if you wish. Just to be certain, I checked with the manufacturer who told me the same thing.

Recommended Strap Hinges For 4 x 8 Foot Doors for Enclosed Trailer
What you're planning sounds like it would work, but you'll need to be sure you have some cross members in the door where each hinge mounts. Since the doors are large and are likely pretty heavy, I'd use the biggest hinges you can. If you were wanting the hinge to swing all the way up against the side of the trailer, I'd recommend using # 2212. A hook and keeper, part # 383400 would hold the door open for you as you load/unload. If you only need the door to swing 180 degrees, use # 2512....

Hook and Keeper on Side Door of Haulmark Trailer
The Zinc Plated Hook and Keeper # 383400 is a universal fit so it will likely work on your Haulmark trailer. It's a 4 inch hook with mounting holes that are spaced 2-5/16 inches horizontally and 1 inch vertically.

What Position Should the Hook and Keeper for Enclosed Trailer Doors Be Mounted In
Correct, the mounting holes on the Hook and Keeper for Enclosed Trailer Doors part # 383400 are 2-5/16" apart top to bottom (vertically) and 1" apart left to right (horizontally). The actual plate measures to be 3" tall x 1-3/4" wide. Therefore, it is taller than it is wider. I have attached a few photos to clarify the above.

Trailer Door Hook and Keeper are Not Lined Up Properly on a Outback Enclosed Trailer
So when you open the door and swing the hook part out to meet the keeper the door hits the fender before the 2 can reach each other? If that is the case then I would agree that somewhere along the line a mistake was made. The only hook and keeper we have is # 383400 and the hook is just 4 inches long. The best solution is to move the hook and/or keeper. It sounds like the screws used are Torx style or something similar. A hardware store should have the appropriate tool to remove and reinstall...

Can a Horse Trailer Back Door be Left Open or Will it Damage the Hinges
It really depends on how heavy the door is, how far it sticks out from the hinges, and how big the hinges are. You could technically say the same thing about any door that mounts on hinges. So the doors in your house you would not necessarily be closed all the time. But at the same time the distance between the ground and the bottom of the trailer door is greater than that on a door in your house. In other words, a sagging door in a house would only go so far before being held up by the...

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.

Why Doesn't Enclosed Trailer Door Hook and Keeper # 383400 Come with Install Screws
The Enclosed Trailer Door Hook and Keeper # 383400 does not come with new screws because different applications will require different fastener styles and lengths. So instead of giving screws that would end up getting misused in some applications they let the customer decide what would be the correct install hardware to use. I attached an install video for you to check out as well.

Availability of Brackets that Hold Trailer Doors Open
We have brackets that hold trailer doors open like what you mentioned. We have the part # 383400 for a metal bracket style. Or if you wanted a plunger style that would just require you to push the door in place you would want the part # DH39R.

What are the Dimensions of the Enclosed Trailer Door Hook and Keeper # 383400
I went out to the warehouse and pulled Enclosed Trailer Door Hook and Keeper # 383400 to measure it. First, the mounting holes are 2-5/16 inches across on center and 1 inch top to bottom on center. The mounting plates for both pieces are 3 inches by 1-3/4 inches. From the center of the hook piece to the end of the hook is 4 inches. The hook piece sticks up 1/2 inch from the mounting surface. The keeper piece sticks up 3/4 inches from the mounting surface. I have also included a picutre...

Latches for Securing Ramp on Open Landscaping Trailer
Without knowing the dimensions and weight of your ramp it is hard to make a specific product recommendation but we do offer all sorts of trailer hardware. You might do well with an inexpensive hook and keeper like # 383400 or # PLR9-SS, or a spring latch like # SL716. I recommend using one latch on each side of the ramp.

Trailer Door Holder that Wont Accidently Release the Door
I do not have a way to test how much force it takes to pull the rubber stem from the socket # DH39R (no force gauge available) but having used this type of door keep before I can tell you that it usually takes a good jerk to free it up. When you want to be positive that the door is going to stay open I recommend using a hook and keeper such as # 383400. I have linked a video review for you.

Will Enclosed Trailer Door Hook and Keeper 383400 Work on a Heavy Horse Trailer Door
Even though the door on your horse trailer is heavy the door keeper # 383400 will still hold it open. Nearly all of the door's weight will be on the hinges and the keeper is just preventing it from closing. The keeper is not really supporting any weight so it will work well for you. I have linked a video showing an example installation.
