    1-1/2″ × 3″ INTERLOCKING HORSESHOE SHIMS

    Glazelock 1-1/2″ × 3″ Interlocking Horseshoe Shims provide stable, adjustable spacing for window and door installation, curtain walls, storefronts, cabinetry, and other leveling and alignment applications. Glazelock’s patented interlocking design allows multiple shims to snap securely together, helping keep stacked shims aligned without tape or glue.

    The U-shaped design fits around bolts, anchors, and fasteners up to 1/2″, allowing the shim to be positioned around an installed fastener. Use individual shims for fixed spacing or interlock multiple shims together to build the thickness required for the application.

    Made from durable high-impact polystyrene (HIPS), these plastic horseshoe shims resist splitting, rot, shrinkage, and swelling. Three color-coded thicknesses make identification easy: 1/16″ blue, 1/8″ red, and 1/4″ black. Multiple package quantities are available for everything from smaller jobs to production and commercial use.

    Glazelock Interlocking Horseshoe Shims are commonly used for window and door installation, curtain wall systems, storefront glazing, cabinetry, millwork, and general construction leveling and alignment.
