    TAPERED WEDGE SHIMS – PRECISE ADJUSTMENT WITH SECURE GRIP

    Glazelock Tapered Wedge Shims provide a durable, adjustable solution for leveling, spacing, and alignment in window and door installation, cabinetry and, other construction applications.
    Each 7-3/8″ shim tapers from 1/4″ at the thick end to approximately 1/32″ at the feathered end, providing a wide range of adjustment from a single shim. The molded stair-step grip helps the shim maintain its position after adjustment and also allows opposing wedges to grip together when used as a pair.

    Perforated break lines allow excess shim length to snap off cleanly after installation, leaving a neat finished installation without the need to cut the shim.

    Made from durable high-impact polystyrene (HIPS), Glazelock Tapered Wedge Shims will not rot, shrink, or swell like wood. They’re available in both bulk and individually packaged 12-shim retail packs.

    Glazelock Shims are made in the USA.

What our customers say.

  • We have been using Glazelock’s Interlocking shims for over 5 years now. They simply snap together to get our desired thickness. No more taping or glue shims together, saving us time and money.
