The leg SM consists of two extruded aluminium profiles with a plain anodised finish, guided by plastic gliders. Each leg has an internal motor that drives the threaded spindles. Up to 12 spindle Lifting legs can be connected to one control box and are operated synchronous.

The T-slots on 3 sides (width 8 mm) allow the addition of crossbars, shelves, attachments and mountings along the entire length of the leg.
