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.


The parts were hard to find but you had exactly what I needed


Perfect Fit!!



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


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.


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


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


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


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





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.


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.


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 would work better for you.


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


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!!!


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.


Gentlemen, Your shipping was very expedient. Your products were quality, worked very well--I am very happy with your company. Thank You!


Fast shipping exact replacement


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


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


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.


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


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!!


This was exactly what I needed and was able to replace my broken hardware with it as I expected. Came quickly and in good order!! I will use this vendor again...



everything i ordered
from etrailer worked great


Just as expected and shipped quickly. Only reason I didn't give it the highest score is that i wish you had a stainless steel version!


Just what I was looking for, quality product at a low price and very reasonable shipping rates. Received in a timely manner with excellent updates on my order.

  • Replacement Door Holder Plunger and Socket Options for a Hahn Heavy Rescue
    The plunger must be larger than the opening on the socket in order to hold it in place. With the Pivoting Door Holder Receiver # 37210635 having an opening slightly over 1/2" and your current socket measuring slightly under a 1/2", I would have to lean towards it not working because of the size difference. In my opinion, I would replace both the plunger and the socket to ensure that they are a good fit. - Plunger and Nylon Socket Door Holder # DH604 (1" long plunger) - Plunger and Nylon...

  • Could Nylon Plunger and Sockets # DH604 and # DH605 Fit 2007 Winnebago View
    The plunger and sockets part numbers # DH604 and # DH605 are a very universal design that would work great on your 2007 Winnebago View.

  • Door Holder and Socket Replacement Parts
    Every steel socket and plunger we sell comes with a Zinc coating to help with corrosion. Zinc corrodes approximately 100 times slower than other metals because it develops a thin gray oxide film which inhibits deeper oxidation. We sell replacement parts for the plunger and for the socket together or separately and in different sizes. I've listed a plunger and socket set for you as an example below: Plunger and Nylon Socket Door Holder - 2" Long Plunger Item # DH605.

  • Will a Plunger that is 19/32" in Diameter Fit with the Replacement Nylon Socket # DH600S
    Since the hole diameter of the Replacement Nylon Socket # DH600S 1/4" I recommend just getting the whole kit to ensure they work together properly. We have part # DH604 which has a 1" long plunger and part # DH605 which has a 2" long plunger.

  • Available Plunger and Nylon Socket Door Holder
    The # DH604 and # DH605 come with both the plunger and the nylon socket, which is where the difference between the part you've linked and the parts you're referencing on our site. These are sold as sets of 1. The Replacement Nylon Socket for DH604 and DH605 # DH600S is available if you're just looking for the nylon socket and not the hardware/plunger, which is also sold singularly.

  • Overall Length of Plunger # DH605P
    The 2" Replacement Plunger for DH605 # DH605P that you referenced is 2 inches in length. If you need something similar to this your best option would be to go with the # DH605 which comes with a new plunger and socket instead of trying to fit your older socket that may be worn out at this point.

  • What Size Does the Plunger Need To Be To Use the Replacement Nylon Socket
    The diameter of the plunger that the Replacement Nylon Socket part # DH600S is designed to fit will be around 1/2" give or take 1/8". The plunger must be larger than the opening on the socket in order to hold it in place. That said, in order to make sure you get an exact fit it would be best to just replace both the socket and plunger with part # DH604 for 1" or part # DH605 or 2".

  • 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...

  • Door Holder For Trailer Entrance Door
    I'm not 100 percent sure what you mean by "cylinder" though we do have some door holders for your trailer's entrance door. These partss are add-ons, however, as opposed to replacement parts: - C-Clip Door Holder - Polar White: 3" # 37210204 or 5-1/2" # 37210374 - C-Clip Door Holder - Zinc Plated Steel: 3" # 37210535 - Plunger and Nylon Socket Door Holder: 1" Long Plunger # DH604 or 3" Long Plunger # DH605 I have added links to video reviews for you to check out as well.
