The DORMAKABA COMMERCIAL HDWE 8Q00302 is an SFIC tailpiece designed to connect a Small Format Interchangeable Core (SFIC) cylinder to the locking mechanism inside a commercial lockset. The tailpiece transmits rotational motion from the core to the lock cam or bolt, enabling the lock to retract when the correct key is turned. At 2 inches in length and 0.5 inches in both width and height, this is a compact but essential component. It is typically installed by commercial locksmiths and door hardware technicians during core replacement or lockset service.
This tailpiece is suited for commercial door hardware applications where SFIC cylinders are used. SFIC systems are common in institutional, hospitality, and commercial facilities that require frequent rekeying or master key management without removing the entire lockset. The 8Q00302 is sold individually and is intended for use during scheduled maintenance, hardware upgrades, or lock core swap-outs in commercial buildings.
Designed as an OEM-style replacement tailpiece for commercial locksets that accept Small Format Interchangeable Core cylinders.
Installation is typically performed by a licensed commercial locksmith or qualified door hardware technician. Before servicing the lockset, ensure the door is secured in an open position and that access control or alarm systems tied to the door are disabled. The tailpiece must be correctly seated in the core drive channel and lockset cam slot before the core is locked into place. Refer to the lockset manufacturer's service documentation for proper alignment procedures.
