Stanley Hinges have been re-branded as Best Hinges. Packaging may change but it’s still the same quality hinge you have relied on for decades from Stanley. Depending on stock levels and availability these hinges may be shipped with the Stanley or Best packaging.

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.

• Meets Industry Standards ANSI/BHMA A156.1
• For medium weight doors of average frequency
• All hinges have template screw hole location for use on either wood or hollow metal doors and frames
• Equipped with two Stanley permanently lubricated non-detachable ball bearings
