Much better than the original equipment plastic keepers on our horse trailer. These are easy to engage, durable and look good.



by:

Great product easy to install. Quick shipping and great customer service answered questions accordingly



by:

Used to replace a plastic door holder that broke on a horse trailer. Holds door open well.



by:

This is exactly what I needed! My previous hold back (that was factory mounted) drug the running board and didn't always allow me to open my tack room door. I love that this one stays up against the trailer & has lifetime warranty! No more issues opening my door :)



by:

At the moment, I can't complain about the products. My only complaint for now, I wish etrailers was as expedient about sending my product out, as they are asking my rating and opinion. It took too long to get out the door, literally.



by:

Works perfectly



by:

I took a gamble that it would fit my application, it doesn't. The issue is the 45 degree angle, I don't have it so I will do some metal working and make it fit.



by:

Just wish they sold one in different le ngths



by:

Exactly what I needed for 2022 Winnebago ViewD. Works just as described!



by:

The problem I was having was that when the front door was all the way open and latched, it blocked access for the storage door to open. I always had to unlatch the front door, put a temporary wire on it to hold it open. I was then able to access the under storage. I thought the 45 degree latch would be a perfect solution, and it was with some modification to the catch. Even though the latch is 45 degrees, the catch is still made for a straight on latch. I didn't even take that into consideration until I dry fit it and matched the angle to the dangle. My dremel rotary tool allowed me to make the needed modification. Now it works great. Thanks etrailer!

  • Recommended Door Holder to Hold a Trailer Door at a 45° Angle
    Hey Lyndon. For a door holder that will open your trailer doors to a 45° angle, I recommend the Keeper Door Holder item # 37211765. This holder is also a t-hook style but it's been designed specifically with a bend and will prop your trailer's doors open at a 45° angle. The Keeper Door Holder item # 37211765 is sold individually and comes with two sets of mounting brackets and the necessary installation hardware. If you would like me to take a look at your pictures, you can send them...

  • Looking For Replacement Trailer Door Hook And Keeper
    Hello Hunter, thanks for reaching out. That appears to be a standard 45-degree T-style hook and keeper. We do have a suitable replacement for this. I recommend the following: - 45-Degree T-Style Hook and Keeper Door Holder for Enclosed Trailer - 3-3/4" - Stainless Steel # 37211765 This comes with the spring-loaded hook and keeper. The mounting holes are 1" apart vertically and 2-1/4" horizontally if you want to measure and confirm fit. What kind of trailer do you have?

  • Recommended T-Style Hook and Keeper Door Holder for Featherlite Enclosed Horse Trailer
    Hey Heidi thanks for the pictures! You are correct you do need the 45-Degree T-Style Hook and Keeper Door Holder for Enclosed Trailer item # 37211755. It is 6" long and has a 45 degree hook and keeper like yours. As far as removing the old ones go. You'll want to center punch all of the rivets with a chisel and then you can drill them out with a small 3 mm drill bit. If you have any additional questions feel free to throw them into the comment box below and I'll be happy to answer them.

  • Recommended Trailer Door Keepers for Horse Trailer Main and Tack Room Door
    Since you have some obstructions on the side of the trailer preventing the main door from swinging all the way open you'll need to use an angled door keeper like the 45-Degree T-Style Hook and Keeper Door Holder part # 37211765. Then for the tack room you should be able to get away with just a standard keeper like the T-Style Hook and Keeper Door Holder for Trailer Rear or Side Door part # PLR9-SS. I have attached a full list of options below as well if you don't think the above will work...

  • Door Keepers For Holding Enclosed Trailer Entry Door Open at 90 Degree Or 45 Degree Angle
    The 45-Degree T-Style Hook and Keeper Door Holder # 37211765 and 90-Degree T-Style Hook and Keeper Door Holder # 37211785 would allow you to hold your entry door open for additional ventilation. While these are stainless steel and very strong I would warn against using in very strong winds as it could damage the door or trailer skin if a strong enough gust is blowing. You can use multiple holders on the door but do remember to unhook them before trying to close or open the door. The hook...

  • Recommended Sealant For Old Mounting Screw Holes In The Side Of An RV
    You can use some Non-Sag Sealant # 344270341437-1 to fill in the old latch screw holes when installing your new 45-Degree T-Style Hook and Keeper Door Holder for Enclosed Trailer # 37211765.

  • Door Keeper Options for Horse Trailer with Swinging Rear Doors
    If you have obstructions on the side of the trailer that would prevent the door from swinging all the way open then you will want to consider using either an angled door keeper like the 45-Degree T-Style Hook and Keeper Door Holder part # 37211765 or an extended one like the T-Style Hook and Keeper Door Holder for RV or Enclosed Trailer part # 37210515 for 4" or part # 37210525 for 6". In order to confirm fit you will need to measure to see how far away from the trailer the door can get...

  • What To Do If Your Entry Door Open Angle Doesn't Match Up Well To The Wall For A Door Holder
    A shorter hook would help with the angle of the door to help get the hook into the holder for your trailer's door. An option with a 45 degree bend in it, like the part # 37211765, would give you a better option to work with the angle of the door, but you might have to change the placement of the holder to properly fit with the door. I recommend installing the hook on the door first and then holding the door up to the wall of the trailer to find the correct spot for the holder. This would...

  • 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.

  • Your camper shell will be fine using the 45-Degree T-Style Hook and Keeper Door Holder for Enclosed Trailer - 3-3/4" - Stainless Steel Item # 37211765 to hold the door open, even in the wind. I recommend using some Butyl Tape Item # 344270341411-1 on the brackets to ensure a water tight seal in the screw holes and will also add some extra grip strength to your brackets.
