Shelf Angle (Wedge) Inserts & Shims
 
 
   
 
When cast into concrete, Wedge Inserts and Askew Head Bolts provide a secure and adjustable method for fastening shelf angles and other materials to concrete structures. The anchor's wedging action reduces slippage to a minimum. Shelf Angle Inserts allow vertical adjustment so veneers can be properly aligned despite construction tolerances in the building frame.
   
             
Shelf Angle Inserts
 

#425: Wedge Insert

These heavy-duty malleable iron inserts have three holes for nailing to forms. Anchor loops are designed to take 3/4" (19 mm) reinforcing bars or anchor rods for increased anchorage in concrete. Available plain or hot dip galvanized. Wedge inserts should be installed a minimum of 1-1/2" from the concrete edge.

#427: Askew Head Bolts

The wedge-shaped heads of these steel bolts compliment the wedge-shaped inside face of the Wedge Insert. Available plain, electro-galvanized, or hot dip galvanized. Furnished with washers and nuts.
