Q: What are CB Series hinges?
A: CB hinges are concealed bearing hinges that have vertical and lateral wear performance that exceeds ANSI/BHMA Grade 1 standards. The LifeStan patented bearing system is a revolutionary concept in bearing construction and materials. It eliminates metal-to-metal contact between knuckles by creating its own bearing surface between the washer and sleeve. 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 which provide for an aesthetically pleasing appearance.
