Ball Bearing Slide Pack for 1121 Series Low-Side U-Channel

This kit allows you to connect one U-shaped track to another, creating a sliding cascade structure similar to an extension ladder. Each end is equipped with four bearings that lock the tracks in place and support each other.

• Weight: 71 g
• Material: High-carbon steel (bearings)

When folded, it adds only 8 mm to the total length of two equal tracks. The total length when unfolded is 40 mm less than the sum of the two tracks, ensuring compact storage and smooth sliding during use.
