Good strong exact replacement for the cheap cast hinges on my horse trailer tack room door.



by:

These were a perfect fit, and very good quality. Quick shipping too, thank you. Used for a 2005 Trails West Horse trailer, tack room door.



by:

Trailer door hinge was exactly what I needed. Just like the original. Delivery was prompt. Hinge easy to install. A year later hinge is in great shape.



by:

I decided on these stainless steel hinges as a replacement over a set of chrome plated zinc cheapies because the hinge is bushed with SS instead of plastic, which is what failed on the original hinges. I feel these hinges will be the last ones I ever have to replace as the quality is far superior.

by:

The product was exactly as described. It was delivered quickly and installed (replaced the pot metal ones original to my horse trailer escape door that were breaking/broken) using the original hardware) with ease. Strong/sturdy and work as expected. Great product.



by:

I was super impressed with etrailer. My hinges were back ordered abs they emailed me several times to make sure I didn’t want to get something else that would come faster. These hinges look great. Thank you for the great service



by:

Always love purchasing from etrailer, fast shipping, exactly as described. This is our 2nd purchased hinge for our old 1997 sundowner LQ 3 horse trailer
We purchase when one of the old ones finally breaks.



by:

Very overpriced for ONE hinge, this one is not nearly as think as the original. Pretty disappointing for price.



by:

The hinges are for our horse trailer tack door. They are much higher quality than the originals. Thanks for getting them to us so quickly.

Great No Problems



by:

I need a hinge for our Starcraft - 1970 Vintage RV - and etrailer has one that matches perfectly - well made, shiny polished stainless, these will be the perfect replacement for the long missing original parts. When I find something that works and is built well, I always go back and etrailer not only had the right part, but they were quick to ship and follow up to make sure it arrived. Good service, good product, highly recommended. Kudos. I'll post a pic of the hinges installed shortly.



by:

Perfect fit, great quality and fast delivery. Could not be happier.



by:

Great upgrade replacement for the original ones, one of which broke on a trip. etrailer was able to overnight them to me so I didn’t miss a beat on my trip plans.

Still looks and works great after a year of use!



by:

So far holding up well on horse trailer replacement on two 3' by 6' steel doors.
Half the driving on gravel roads so hard on trailer. Direct replacement on Trails west trailer. Actually, better than what came on it. These are stainless steel the original ones were cast alloy and all broke at the hinge pins. These also matched the screw holes perfect.



by:

Excellent quality and easy to install. They are just what I needed for my custom teardrop trailer doors!



by:

Seem well made. They should work better than the aluminum ones I have.



by:

The hinge worked great.



by:

EXCELLENT, exactly what I needed.

Stainless Steel hinges _still_ look like brand new after a year!



by:

These hinges worked great for replacing my old ones on my tack room door.



by:

The hinges I ordered are exactly what I've been looking for. I couldn't find them anywhere!! And the packaging and delivery was excellent! Perfect fit our pest control truck



by:

Sturdy hinges used on custom camping trailer doors.
They worked perfectly.



by:

Fast shipping. Just what I needed to replace the old broken hinges on my trailer door.



by:

These hinges are extremely well made and solid. They are môre pricier than others found on Amazon but it well worth it. The quality is great and works well on the doors on my little custom teardrop camper.



by:

Great product, I actually just installed them yesterday evening. Had to do a little modification since I didn't take the measurements of the previous ones it had, (my mistake), but nothing a little drill action can't fix.
Now looks good and works great!

The new hinges look great! Sometimes replacement parts aren't a perfect fit so some modification can be required. I'm glad it was a simple fix to get it installed!

See what our Experts say about this Polar Hardware Trailer Door Hinges

  • Can Rivets Be Used to Install Polar Hardware Strap Hinge
    Hey Phil! I can't say for sure on the bushings but, based on my experience with trailer parts that is likely correct. The recommendation is for #10 screws because it is pre-drilled for the screws and your average person is likely using screws and not rivets. You can certainly use rivets to install the Strap Hinge # PLR104SS if that works better for your application. If you take a look at the picture below you will see where another customer used different hardware for different holes....

  • Replacement Door Hinge for Trails West Horse Trailer
    We do have a large selection of door hinges available. I recommend taking a look at the Polar Flush Hinge # PLR104SS. This looks very similar to the hinge you have pictured on your Trails West Horse Trailer and it features the same number of bolt holes. It has an overall length of 5-1/2 inches and the base measures 3-1/4 inches tall. I have attached an image with these and some additional dimensions labeled that you can also check out.

  • 1958 Silver Streak Replacement Entry Door Hinge Recommendation
    To replace the door hinges on your 1958 Silver Streak travel trailer I recommend choosing from the following 2 options: - 5-1/2" Long x 3-1/4" Wide Stainless Steel Strap Hinge # PLR104SS - 9-1/8" Long x 3" Wide Stainless Steel Strap Hinge # PLR109-SS These are pretty straight forward hinges but since the length varies one might work better for you than the other. It doesn't look like we have any exact replacements so you'll want to use something that's functional, and since these have...

  • Is There Left And Right Versions of Door Lock for Horse and Utility Trailer
    There is not a left or right for the Bauer Products Door Lock for Horse and Utility Trailers - Matte Black - Glass Filled Nylon # BA63FR or Die Cast Zinc # BA93FR. These are meant as replacements so they would work so long as your cutout is the standard 2-3/4" wide x 3-3/4" tall; it also requires a 1-1/4" to 1-1/2" thick door, and since yours is 1-1/2" thick you're set there. As for the models, I do recommend the Bauer as they consistently make quality parts, and you're right that the...

  • How To Confirm Fit and Install 5-1/2" Long Strap Hinge
    The Strap Hinge part # PLR104SS is a universal trailer door hinge. The best way to determine replacement is based on length which for this model is 5-1/2" long. The hinges can be riveted or screwed on. If your old one has rivets they will need to be drilled out to remove them. The new one then can be attached with screws for an easier install or a rivet gun if you have one. Please note, we don't have any info on the door hinge on your trailer currently so measuring is best to determine...

  • What is the Weight Rating of the Polar Flush Hinge
    The Polar Flush Hinge - Stainless Steel # PLR104SS is not rated for a specific weight because you can simply add more hinges as needed to support the weight of the door. The screws used and the door material will greatly impact the weight capacity.
