CB Series hinges are concealed bearing hinges that have vertical and lateral wear performance that exceeds ANSI/BHMA Grade 1 standards. STANLEY Security patented a revolutionary bear construction called LifeSpan® to eliminate metal-to-metal contact between knuckles. As the stainless steel washer extends into the sleeve, it eliminates metal-to-metal contact between the pin and barrel, resulting in a smooth, quiet operation superior to that of a ball bearing assembly. In addition, the concealed bearings allow for fewer horizontal barrel lines that provide a more seamless appearance. The CB Series is ideal for medium to heavy weight wood and metal doors in high frequency usage applications.
