Why This Staple Matters
The P21BAB combines heavy-gauge strength, deep-leg length, and a wide crown — making it a dependable choice when you need strong structural fastening. The 2" legs ensure staples embed deeply, improving hold in thick or layered materials, while the 1" crown distributes load to prevent tear-through. The galvanized, coated finish improves durability and helps staples drive smoothly, even under tough conditions — ideal for construction framing, subflooring, pallet/crate building, roofing, and other heavy-duty staples use cases.
