MODULITH 185 Under-Table Rails
formerly GEN2Screw these to the underside of a desk or bench and cases slide straight in - the rail carries its own drawer stops for the top row. Match the rail's depth to the cases sliding directly into it; mounts with wood screws.
Installation guide: Under-Table Rails
Screws to the underside with countersunk wood screws - #6 × 3/4" (19 mm) is the default; a 3/4" screw reaches about 16 mm into the top, so check the surface is thick enough - minimum 2 + 2 per 1W of section width · see Purchased Hardware for the exact list.
Shows the main printed body in its recommended print orientation - separate pieces (labels, accents) and removable print aids aren't included.
