Easy way to mount items so they can slide along a pipe.
The double roller prevents tipping when force is applied in the direction of rolling.
Designed for pipes with a 25 mm outer diameter
Also available as a single-roller model. Includes a stopper for securing to the ceiling.

I use it as a mount for a vacuum hose along with rubber bands.
