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


This part is exactly what we needed. It was priced right and shipped quickly. The customer service is excellent. The original order was showing "delivered" but I did not receive it. When I reached out to the etrailer, they immediately shipped out another one - no additional charge and no questions. Turns out the original one was left in my neighbor's mailbox and it took her a few days to let me know! I will be returning that original one to etailer. I will definitely use them again!!!


Very tight fit, very hard to get door out to close


As ordered


Perfect Fit!!

Still in great condition after a whole year in the tropical island of Puerto Rico!!! I would definitely recommend it!!!

I'm so happy with this purchase. Our horse trailer's drop down windows were not staying open and these parts were not as easy to find as I'd hoped. I was excited to find them on but was worried they would not arrive prior to our trip (NC to MT). No worries as they arrived very fast, were easy to install and hold tight. Love the quality & great service. Thank you etrailer


Now I can STOP struggling with the wind !!!

Just great!!! Windy days dont bother me now! Holds in a strong gust of wind too! SO helpful.

Super quick and everything looks good


Good product, great service! Now I don't have to hold my door open anymore.


Product is well made and quick to install,doors on wheel loader would not stay open the factory latches are broken and its an old machine so not wanting to put alot of money in it I tryed these and they work great and at a good price. I will buy more when something else gos bad. Thanks, Bill

Still working great,and they have been used alot in the past year.

This was an easy replacement and works like a champ. Since it is still very new, it sometimes holds the door open too tight. But also the wind can't blow it shut by accident. It will loosen up in time.


The product is good but the plunger was too short to use as a replacement however I did use the nylon socket and my existing plunger and it works fine

Joan - 03/11/2019


The plunger and socket arrived extremely fast. Super happy with the seller. The item however is ridiculously tight. Once the plunger is in the socket it is extremely difficult to separate. Regretfully I placed it on my aluminum sided RV. And almost ripped the siding off trying to open the door. I do not recommend this item for Light RV trailers. This is something more appropriate for industrial type trailers or horse trailers. Great product for industrial purposes, absolutely not for recreational RVs.


Very clean and exactly what they were in the picture and work and hold great


They always have everything I'm looking for!


Good quality. Product took longer than usual to ship due to Mfg back orders.
Pleased with ETRAILER customer service keeping me informed of when product would be fulfilled and shipped.


This item was purchased to replace an identical item. It arrived on time, was exactly what I wanted and was very easy to purchase on line. I would use again in the future if the need arises.


Works great holds windows on horse trailer. Keeps the window from flopping when windows are dropped down while traveling.


Exact replacement for the doors on my Holiday Rambler Presidential 5th wheel.


buddy bought a camper shell with one broken off, was the first website to appear on bing with what i was looking for


well made product. Was disappointed that the screws were not included to assemble to my camper.


I wanna to thank etrailer because I sent this part to my father in Puerto Rico, you cannot find them over there!! The truck looks way better now and my Dad is super happy!! Fast delivery and great service!!


The 2 “ is a little short and won’t line up with my application. My mistake. If the metal part were a couple inches longer it would work. It’s otherwise a quality product.

It sounds like a Hook and Keeper set-up with a 4 inch long hook, part # 383400
T-Style Hook and Keeper Door Holder for Trailer Rear or Side Door - 4" Hook - Zinc Plated
would work better for you.

This was the only place I could find these parts. Exact replacement for my EXISS horse trailer.



everything i ordered
from etrailer worked great
