Non-Square Edge Applications

The articulating arms below (with 7 1/2" necks) provide complete extension and proper storage on worksurfaces where the bottom surface is not flat at the front edge, including 18th century traditional edge, Bull Nosed-radiused under, bevel-knife edge. We designate these as undercut (UC) surfaces.

Height range - 10-3/4", 2-1/4" above to 8-1/2" below a 1-1/4" thick worksurface (3-1/2" above track to 7-1/4" below track).
