Glazing Shims — Horseshoe & U Shims by the Box

Plastic shims for levelling, aligning and spacing windows, doors, storefronts and curtain wall. Both lines have an open slot, so the shim slides in around a bolt or anchor that is already in place instead of having to come off it.

They will not rot like wood or rust like steel, and every shim in the box is the same thickness, which is what you notice on a long run of storefront.

The two lines are not interchangeable. Horseshoe shims are 3" x 4" with a 7/8" bolt hole; U shims are 1-1/2" x 2" with a 1/2" bolt hole. A 1/2" slot will not go round a 7/8" anchor.

Both lines are on the shelf and priced by the box — 50, 100, 250, 500 or 1,000 shims, one gauge per box. Horseshoe comes in four gauges (1/16", 1/8", 1/4", 1/2"); U shims in five (1/16", 1/8", 1/4", 3/8", 1/2"). Fifty is what a crew gets through on one job; the larger boxes run several jobs off one order.

The gauge is embossed on the horseshoe shims and printed on every U shim box label. Colours vary between production runs, so order by the size, not by the colour.
