Quality is great, install was easy. I do wish etrailer sold the rivets needed to attach this product.

These can be installed with a quarter inch self tapping screws.

I bought these to replace one on my horse trailer that had lost a screw and fallen off and I’m so disappointed. They work perfectly fine as long as you aren’t moving. Once you start driving and hit a bump the plunger pops out and either the door swings closed or starts flapping around in the wind and you have to pull over to fix it. I had to haul my horse 2.5 hours in the heat last weekend and had to stop at least 5 times to open the doors back up because they kept coming undone. Really wish I’d bought something else instead.


Comments
Thank you for your review. This door holder is meant to hold trailer doors open during loading and unloading. This is not supposed to be used to hold doors open on the highway. You can watch our video about the product here:

Very good follow up and updates on my order. Product is exactly what I expected and good heavy duty piece.



- PLR64-66
by:

This is a very well made heavy duty product. However, I installed it on a 46 degree day (which is to be expected on many a camping trip) and the rubber grommet in the female piece is so stiff that I was afraid of actually breaking the door in trying to get it to engage! I am hoping that it will soften up in warmer climes- if not I will ream it out a bit with a drill bit.



- PLR64-66
by:

The rubber socket is VERY tight and reuires effort to attach and detach the plunger. It may improve with time.

Exactly what I needed. Will order from e trailer again !

I remember seeing this on an old 60's trailer that I camped in as a kid. I currently have a 1990 layton skyline. My door was missing a door holder so I purchased this one. The door I have is very flimsy so this wasn't a very good fit for my door(this door holder requires you to push fairly hard to get the knob in the grommet). I ended up reinforcing my door with some plywood on the inside and bolting this door holder in place through the plywood. The door is still a bit flimsy but this will do the trick.

Great product heavy duty. Much better than the one that was on the trailer to start with. So glad I bought 2 going to replace the other one. 5 star for sure thank you will search your site for future items as well very fast to ship and great prices

I have a 1995 Northstar popup camper and this door holder nicely replaced the old broken plastic one. The mounting hole locations were slightly different but I'll fill the unused holes. Thanks etrailer.

In all my years of working with trailers, these are the absolute best Socket Door Holders I have found! No matter how hard the wind blows, my doors stay open! With this modification I can work from any busy street and not worry about my trailer doors blowing open and hitting a passing car!

Purchased this item a year ago now on my camper to prop the door open. Worked great for about 3 months then the rubber insert seemed to work itself loose every time I un-propped the door the rubber would come with it..I don't no if it was just a malfunction with the single part I ordered or every part but I threw some industrial adhesive I got from work in there and took care of the problem..but, all and all works great for my use

Seems like a good fit for my Scotty trailer restoration. Just about ready to roll! Thanks! PS great customer service always with you.

Shipping was great. The product is right on time. I go in and out of my trailer a lot and this will keep me from having to bend down to hook the door latch.

This part is used in our fleet of vehicles and is doing what is to designed to do..

Works great. Had a cheap plastic one that broke in a year, this thing will last longer than the rest of the trailer. Just make sure that you mount it with good hardware and into a stud or frame.



- PLR64-66

I can only give 4 stars because I was sorely disappointed to find that there were no bolts or installayion hardware that came with this item. I mean c'mon, bolts cost pennies. Charge an extra dollar if you have to but include the bolts to install. Show that you care about the customer. Now I have to go out of my way to get bolts from hardware store. The manufacturer should should a little more care for the end user and include mounting hardware.

Product worked quickly, easy to install and good prices.

Its been a year and it still works fine. Its terrible when you have to load and unload and the door wont stay open. And it wasnt expensive.

Not sure what this item was originally designed for but I think it was to hold the missle hatch open on a battle ship. Good well made product but would literally hold my RV door open into the wind at 70 miles an hour. Just will not work for what I wanted it for.

The product arrived in good shape & qui ckly.
