Glazelock Plastic Stackable Shims

The Glazelock Stackable Shims are high impact polystyrene shims that easily break apart to simplify applications that require multiple shims. These shims are moisture resistant, and will not rot, shrink, or warp like traditional wooden shims. Their collapsible locking mechanism allows for easy placement. The Glazelock Stackable Shims are especially ideal for window installations that will require the use of multiple shims, but will also work well for other applications that require gap filling, adjusting, or leveling.
