Buying Guide: Choosing Plastic Shims

Shim Styles
Some flat shims, such as the assorted Grab-Box set, fill small gaps and have a serrated surface for non-slip stacking. The small U Grab-Box set has a clip design that holds the shim in place while fixings are tightened. U shims and double snap shims are also available.

Where They Are Used
Some Broadfix shims are widely used in glazing and wall covering work because of their compressive strength and easy stacking. The FS60A-US shim is suited to indoor and outdoor use and is water, rot and termite proof, so it will never warp or swell.

Frequently Asked Questions

What does Broadfix make?

How do I choose the right size or type?
Pick the style that suits the job: flat shims for gaps and leveling, and the small U Grab-Box set, whose clip design holds the shim while fixings are tightened. Check the width and length against the gap or the size on your old part, and use the colour-coded thicknesses to build the right height.

Can these shims be used outdoors?
The FS60A-US shim is suited to indoor and outdoor use and is water, rot and termite proof. Check the product details for the size you need before ordering.
