Quality product, heavy duty. I was rebuilding an old unit and the old scraper seal was in pitiful shape. This is a critical component of the gate opener, as it keeps the inner workings clean and dry plus it 'wipes' debris/dirt/bird droppings/LOL off of the moving arm. And finding Gate Openers Unlimited was a huge added bonus! Arthur kept me consistently updated throughout the buying process, very thorough and professional!
