In 1992, Allen Field Company acquired PX Hardware thus adding a full line of shelf support pins, Shelf Lock™ supports, corner blocks, and protectors. We offer support for shelves in plastic, nickel, and brass. Accommodating all shelf sizes, Allen Field has the right plastic shelf supports and plastic shelf clips to keep your shelves secure during construction, shipping, and everyday use. Our corner blocks and shipping corner protectors keep wooden edges safe during manufacturing and shipping. They are an indispensable accessory in protecting your cabinets, desks, shelving units, and other wooden furniture. Refer to the Shelf Lock™ Quick Guide and ask our customer service reps which locking shelf supports or corner protectors will work best for you.
