These T-Style door holders are exactly what I was looking for for the doors on my sheds. They work perfect. This is the second set of these I have purchased from you, the first set being 5 years ago and are the 6 inch version. They have worked great and I am sure these will be no different.

The door catches are still doing great. In fact I liked them so much I ordered a second set.

Stainless hook and keeper has several rust spots - glad not a new trailer!

Our stock photos have the same marks. I believe those are weld marks.

Works great !!! Now I need a bulb as my tail light is out!

Glad to hear that! What kind of bulb are you looking for? Is it for an RV?

The stainless door hook was in good shape when received and installed easily. I did not have to modify it at all before install as some say they did. It all depends on your application. I used it on a Haulmark enclosed car trailer side door. It works great. This is a good product that I would recommend and buy again if I ever needed one.

The door hook is still functioning well after 1 year of use. It is not rusty as some stainless steel gets. The trailer is stored outside in the elements and is exposed to all weather. I would still buy this again if I needed another.

Great product, good price and fit was e xcellent.


Great quality


Now that one year has past since I purchased the identified trailer door latch ... I thought it appropriate to review this product by way of an update. When I first looked to replace a broken plastic-like door hold-open latch on one of our Boy Scout Troop Trailers, typical of the poor quality ones used these days, I had great difficulty locating a replacement locally in the Aurora, Illinois area. I finally stumbled upon on the internet ... and I am happy I did! I assumed that once I located a replacement latch that I would have to use a similar plastic construction type and I was pleasantly surprised to find a quality stainless steel one from etrailer! The latch works as well today as it did when I installed it one year ago! You can be sure that any future replacement parts my Troop needs for our trailers will be sought after through etrailer! Thank you etrailer! Respectfully, K.C.L.

My Boy Scouts and I are most pleased with the products you provided for us and should we need other parts in the future you can be assured we will be contacting you!

Great product.Im replacing the plastic one that broke after 2 years. This is a heavier stronger latch that I believe will last the life of the trailer.


I have a 2018 Sonoma travel trailer. It came with a strut to hold entry door half way open. I removed strut and added latch to hold door all the way open.
Latch is made of stainless looks and works great.

Good quality part. No rust I used it to convert the door of my sonoma to stay all the way open works well

The hold backs were a direct replacement for the ones on my 2007 Ford cutaway with Whiting doors. I had to bend the arms to make everything align but that's the way the truck was originally designed & built. I 've never seen them sold with bent arms anywhere. The only complaint is why i had to pay shipping on each part? They are very small & light. I ordered two & each cost $4.99 shipping. Overall paid about $24. for them and worth it.

They are just fine, do their job everyday

Perfect replacement for the cheapo plastic door catch supplied on a newly purchased enclosed trailer. Took less than10 minutes to repair - took me more time to find the right screw driver than it did to repair/replace. everything I've ordered/purchased from etrailer has arrived exactly as described and quickly. No need to shop elsewhere - one stop shopping. I can't think of anything that I need that they don't supply.

As expected - much mre durable than the cheapo plastic door holder. Stainless steel has stayed looking like new - no rust or discoloring. Id buy another one if I had a use for it.

Great doing business with this company. The product well described and the item was packaged great for shipment. Great item and thank you


Great products,great communication and super service.How do you beat that combination


Always have what I need


Parts arrived in great shape. Great packaging. The best thing was working with Odelia K. She is absolutely a great asset to your customer service department. I was looking for specific side door bar lock assembles to replace my current ones. I did not want to drill new (more) holes in my trailer. Odelia contacted your supplier and got the actual prints for the parts for me to review. By doing this I could verify that the bolt hole center spacing was exactly like the bars I was replacing. Odelia made great follow up calls back to me and was always friendly and very pleasant. In today's world with customer service almost non existent in a lot of company's she is a gem.


A great replacement for the plastic version we had originally. I fully expect this unit will last longer than our 5th Wheel, and it's in great shape.

Still holding up very well. Sturdy and no rust or corrosion at all.

We are very happy with our trailer door holders. They are stronger than the plastic ones we replaced. We spray painted them white to match our trailer.


Simple device doing exactly what it's supposed to do.


Received trailer door retainer promptly and in excellent condition. It was exactly what we needed to replace the original plastic one. The price was extremely reasonable. Thank you


Great product replaced the cheap plastic latch on my RV door that kept breaking. I hope to get many years out of this stainless latch. Mount holes fit perfect no drilling required


The item that I ordered was exactly what was needed for the job. It was also accurately represented in the picture and the description on the website. It suited our needs when we were in search of some type of door holder for a cooler door in a morgue. It gave us a simple yet effective method of holding the door open when not in use. I was very pleased with the good service, product quality, and product details. All in all, it was a very productive business experience. Thanks for the professionalism.


Very well made and just what I needed for my aluminum stock trailer

The bracket bent the first time I used it. The stainless t-handle bent and pulled out of its mounting. Not very pleased with the product.
Scott L - 07/20/2018


Received the trailer door latches almost immediately after placing the order. Thank you for your prompt and speedy filling of my order. Free Spirit Farm


I came across by accident ( surely not). Sooner Trailers no longer makes these tie backs for my model/year of trailer. I'm SO glad I found you. Can't wait to get this installed, with an extra for good measure.


While the hook and keeper appears to be well made, I was a bit disappointed that mounting screws weren't included. Maybe I am expecting too much from products these days.
