Quoins & Keys

If you’re looking for a fast and simple way to lock your die in the press or chase, look no further. Bar-Plate is now the only US manufacturer of “High Speed” Quoins. Our unique construction applies even pressure across the entire face of the quoin, ensuring a tight fit. Our positive locking feature prevents slippage. The one-piece construction, along with a simple turning motion of the quoin key, provides unparalleled speed for tool lock-up, and special plating prevents corrosion. Each quoin is inspected throughout the manufacturing, assembly, welding and plating process, and each quoin is stamped with a warranty date prior to shipment.
