Typically withstanding ten tons of compressed force, lightweight "U" shaped Grove Structural Shims are designed to fit around bolts and anchors. They are often used for aligning windows and curtain walls, for example.
Grove 3"x3" 1/2" Keyslot Shims are shaped to snap into place around a 7/16" bolt. They have a restricted slot to keep them from sliding off a bolt or anchor when hung vertically. Offered in three color-coded thicknesses.
Grove 3”x4” Horseshoe Shims are shaped to fit around a bolt or anchor. They are frequently used during installation of storefronts, for example, in applications where the shim is placed vertically. Offered in eight color-coded thicknesses.
Grove Stackable Shims are made in very fine thicknesses to allow small, precise increments of leveling or aligning. Multiple shims can be stacked to achieve shimming tolerances down to 1/32”.
Grove Tapered Wedge Shims are easy to use for leveling and aligning dead loads. Designed for easy insertion where installation is required, especially where the object being shimmed is installed first and then shimmed.
Grove Flat Plate shims are used where heavy loads are set on top of the shim, often permanently. Applications include tilt-up construction, precast concrete elements, masonry blocks, and heavy machinery.
Any shape and size of Grove shims can be special ordered in fire-safe, self-extinguishing materials. They are available in both polypropylene and ABS materials. Please click to read specifications.
