This well-designed lift has a load capacity of 40 lb and uses a two-stage lifting mechanism (it stops half-way up so you can ensure your hands are clear).
Bottom and intermediate stop positions are adjustable over a 4" range, while the top stop position can be adjusted over 3/4". (Top position can be set flush with or just above the tabletop.) The mechanism latches securely in all three positions.
The support arm assembly glides smoothly along the back mount track, using eight roller bearings, with the lift force provided by a gas cylinder and cable.
Total travel is about 13 1/2", height is 19 1/2", width is 13" and depth is 11".
Superb design. Made in Germany.
