Shim in a Box

Stop using cardboard shims and upgrade to Trim-Tex Shim in a Box. Unlike paper-based shims, Trim-Tex shims are made from PVC and do not act as a food source for mold. In addition, Trim-Tex shims have large holes that allow stud adhesive to effectively bond the drywall to studs. Shim in a Box comes in 48" strips that can be scored with a utility knife and snapped to custom lengths or cut with snips.
