The Porter-Cable face frame biscuits join material as narrow as 1-1/2 inches. Standard size 0 biscuits are too long for use in 1-1/2-inch stock, but these biscuits are 13-by-30-millimeters. With Porter-Cable’s 557 deluxe plate joiner and these face frame biscuits, narrow stock can be joined quickly and easily. At 5/32-inch thick, they are as thick as standard biscuits and provide plenty of strength for typical face frame construction. The re-sealable tube protects biscuits from moisture to prevent swelling. These biscuits come in a pack of 175.
