3210-0001-0004, Ball Bearing Slide Pack for 1121 Series Low-Side U-Channel
This kit enables one 1121 Series Low-Side U-Channel to slide over another like an extension ladder. Each end uses four bearings to lock the channels together and provide support. When collapsed, it adds only 8 mm to the combined length of two equal channels (e.g., two 288 mm channels collapse to 296 mm total). Fully extended, the length will be 40 mm shorter than the sum of the two channels (e.g., 288 mm channels extend to 536 mm).
