Description
SF31SL was designed to use with up to 1/2″ thick glass panels. The extended throat length allows the hole to be drilled farther from the edge, as suggested by revisions to ASTM C-1048. SF31SL includes a 33/64″ plastic sleeve that covers the M4 screw, and prevents glass edge to metal contact. Includes “S” (safety) cap that hinders unwanted adjustment by manually locking the mechanism.
