Let customers speak for us
from 48 reviewsItem was delivered promptly. Instructions for removal of old knob and installation of stop knob were included and easy to understand. The stop knob performs as expected.

Easy processing, easy to install, and a great safety feature.

The stop knob was easy to install and works as designed. We no longer worry about about our motorhome rolling away with our pups inside. Also, gives me a peice of mind when cleaning the windshield leaning over the dash.

Since we bought our motorhome a year ago, we have constantly been trying to find a product that we could put on the air brake button that would allow nobody to be able to push it in accidentally while we are stopped. We finally found it. It was so easy to install and we love it.

This is handy, no more looking for something like a hair clip or piece of pool noodle to block the brake knob. When it is threaded down it is a positive stop for the brake. If on any slope at all and the brake is released by accidentally pushing the existing knob in the RV would roll and it could be a disaster, so this is a very good thing. The only negative would be it is a little longer than I thought it was going to be.

Awesome product, just pay attention to which knob you're ordering - I made the mistake of going by color and shape and not reading the entire description, so had to return the yellow one and order the red one. Constructed really well and looks to be a nice piece of mind for the 4 legged supervisor who likes to sit in the drivers seat of the motorhome when we step outside without her.Update - Quick and easy installation! (after obtaining the correct one that is....)

I have a 2005 HR Neptune class A. It has a different mounting system so I modified my button to work. I cut off the smooth area below. Drilled and tapped 1/4-28 hole in the base of the button. I tapped the hole as to when it is tight on the threaded pin the letters will be in the position I want. Works excellent and looks outstanding.

Wow, great idea and nice machining! Now I don't have to worry about the dog sending the coach down a hill.

Great communications, clear instructions, easy to install, quality piece.
Haven’t used very long, but so far it’s good!

Very happy with it. Easy to install and works great!

Easy installation, took no time at all. Great idea for added safety when parked since the 4 legged supervisor likes to sit in the drivers seat so she can see all the happenings around the campground. This should become a standard upgrade for any motorhome.

A huge upgrade from the cheap plastic knob. Very satisfied!!

I want to thank the great team at StopKnob. I actually messed up my order, I called them, and they went above and beyond to fix the problem, even though I made the mistake. Great Customer Service!! The knob also looks and works great!!

Es perfecto pero deverian de hacerlo también en color rojo para el trailer!Tuve que comprar dos y pintar uno de color rojo.

Wow, great idea and nice machining! Now I don't have to worry about the dog sending the coach down a hill.
