    Description

    The Glazelock GLZ03 interlocking horseshoe plastic shim is engineered for precision leveling and alignment in window, door, curtain wall and general construction settings. Each shim measures 3" in length, 1-1/2" in width and 1/16" in thickness, and includes a 1/2" slot to accommodate bolts or anchors. These shims are made from structural plastic that resists rot, shrink and swell, and they feature a stackable interlocking design to eliminate the need for tape or glue when achieving exact thickness.
