This 2-1/2" diameter x 2" wide endcap mounts to a side guide roller on your boat trailer to provide additional surface area for improved boat-to-roller contact. Heavy-duty rubber delivers lasting effectiveness.
Features:
Specs:
Endcaps easily install on the same brackets that your side guide rollers are mounted to. Just attach each endcap to the shaft on the outside of the roller bracket, and then secure the endcap in place with a cap nut (or pal nut). Not only do the endcaps provide more surface area for better boat-to-trailer contact, but they also help to keep your boat from being scratched by sharp bracket edges.
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to review part no. YR224-4. This is a Yates endcap for side guide rollers on your boat trailer. The endcap mounts to a side guide roller on your boat trailer to provide additional surface area to improve boat-to-roller contact. This part is constructed of a heavy duty rubber material. It is made in the USA.
This endcap will install on the same brackets that your side guide will mount it too. You will just attach each endgap to the shaft on the outside of the roller bracket and then secure the endcap in place with a cap nut or a pal nut. These endcaps will not only provide more surface area for better boat-to-trailer contact but they will also help to keep your boat from being scratched by shart racket edges. I'm gonna do a few dimensions on this endgap. The overall diameter is 2 1/2 inches.
The width will be 2 inches. This endcap will mount onto the side guide roller that uses 1/2-inch diameter shaft. And that should do it for part no. YR224-4.

perfect fit
Product is good. Keeping me posted on order status was great, as was delivery time and price. I have had to return items in the past, and I was able to do it with extreme ease. Customer service is the best. Order from E-Trailer with no fear.
These rollers help guide the nose of the boat onto the front roller. They fit good and solved the problem of my old rollers letting the boat hit their metal support.
Searched many locations and only ETrailer.com had the exact part I needed. Perfect Fit! I have never got a bad product from ETrailer.com. Thanks
Thanks etrailer for a great experience. Everything from the online shopping to delivery went as smoothly as one could have asked! I will gladly return to etrailer for all my future trailer needs. Thanks Again!!
Just what I was looking for. Quick ship, and easily installed.
Makes my old trailer look GOOD!

Happy with the part, it does its job... .........
Great service; I will order all my trailer replacement parts from you in the future.
