Best (Formerly Stanley) FBB191NRP – 4.5″ x 4.5″ Ball Bearing Hinge (Non-Removable Pin)

BEST FBB Series hinges are ball bearing hinges that conform to ANSI A156.1. These tough, hardened, chrome alloy, vertical thrust ball-bearing assemblies support the vertical load of the door, as the pin bearing on the inside of the hinge knuckles supports the lateral load of the door.

FBB hinges are approved for use on fire-rated doors since they contain anti-friction bearings, a requirement for fire-rated and self-closing doors. BEST hinges have been around since 1843 and is a brand name you can trust.
