Base-Only Top-Crank Models: Loosely Secure Table Base to Tabletop
Position the leg assembly on the face-down table top. Center the assembly on the table so that
neither of the side legs overlap the edge. Measure carefully to ensure that your table will be
positioned correctly as detailed below before drilling.
Mark ¾" hole for crank handle: Trace around outside of leg bracket before removing leg
assembly. Measure from front left corner of leg bracket as shown, then mark hole placement. The
hole should be directly under the center of the leg.
Use the ⅛" drill bit to drill from the bottom of the worksurface completely through the
worksurface as step one in drilling. DO NOT USE ¾" bit. Drill from bottom to avoid damaging
top surface.
