Somewhere in your life is a piece of equipment - a workbench leg, a kitchen table, a window encasement or a door jamb - that is out of plumb. Wedgies Shims come in soft/flexible vinyl or hard/rigid polypropylene. The soft ones can be trimmed with a knife or scissors; hard ones can hold up to 2,000 lbs. Both are stackable, non-slipping and won't shrink, swell or rot with the environment. Sold as a pack of 8. Dimensions: 3.54" x 2.36" x .48".
