4" Square Rubber Bumper Plug End Cap Cover RV Camper Trailer - 2 Pack

Fit good and tight

Tight to install but look great.

They fit like they should

I have a travel trailer with a 4” square bumper that is usually reserved for a sewer hose. While detailing the exterior of the trailer, I washed the bumper and the end caps disintegrated. I do not use this bumper for my hoses, but I do not want open ends. So I ordered these new ones and was happy with their quality and timely delivery. However, when I tried to insert one, it would not slide in because it was slightly too large. I don’t know if it’s my bumper or the end caps, but I used a sharp knife and trimmed some rubber off and split a corner to force it in with a mallet. Now it fits, but I would not recommend doing this if you were going to take them on/off to store your hoses. I would suggest measuring carefully. I guess there are different size 4” bumpers.

Appears to work well. Tight fit and easy to install

Gotta spare in case another disappears

One of the original bumper caps on our Keystone Cougar trailer vanished after one of our (bumpy) camping trips. These after-market replacements fit very snug and have not showed any signed of wiggling off. We don't use the bumper for hose storage, so this is awesome. If I needed to get one of them off, it would probably require some added leverage since they are SO snug!

Seemed very well made, but fit VERY tight. Had to use a rubber mallet to beat it in.
