I used these to make hanging cabinets. Perfect application.

Delivered on time and as described. These are holding up considerable weight and still move freely. Good product.

Good quality, works well. Good value.

I've had these for 3 years now. They all still work good

Has too much play in 1-5/8" Unistut. Being used back to back holding an extension cord. When they come together the cord will turn and the rollers will bind.

Excellent for a sliding door on my barn.

Very smooth action and roll with ease

Used these to keep cord from hanging on my ceiling mounted winch. It rolks and follows the winch with ease.
