Use the Bulldog Hardware Angled Shelf Pins to support adjustable shelving in cabinets, bookcases, entertainment centers and more. Whether your looking to replace a lost shelf pin or add an extra shelf to your cabinet, these shelf pins are sure to provide the support you need. The angled shelf pin fits into the 1/4 inch pre-drilled hole in the cabinet to provide a flat surface for the shelf to sit on. Shelf pins can also be installed in solid wood for stable shelf support by drilling holes in the surface according to the pin's diameter. Shelf supports come in a variety of sizes, so always measure when making a replacement shelf pin purchase. These have an angled design with a 1/4-inch diameter shaft and are constructed of brass plated steel. The package contains 4 angled shelf pins.
