Unlike other cylindrical knob sets that are made from weaker metals, the BEST 8K Series is constructed of steel or brass to ensure the overall strength and durability of the lock. Plus, the knob itself is a single-machined unit—instead of being formed from multiple parts and then pressed and joined into a single unit—to provide more structural integrity and greater resistance against wear-and-tear. The 8K Series, which offers quick, economical rekeying with the BEST original interchangeable core, is commonly used in government and military facilities.
