Q: What are STANLEY FBB Series hinges?
A: FBB hinges are ball bearing hinges that conform to ANSI A156.1. The vertical load of the door is supported by though-hardened chrome alloy, vertical thrust ball bearing assemblies. The lateral load of the door is supported by the pin bearing on the inside of the hinge knuckles. FBB hinges are approved for use on fire-rate doors since they contain anti-friction bearings, a requirement for fire-rated and self-closing doors.
Q: What hinge types are the FBB Series offered in?
A: FBB hinges are available in full mortise, half mortise, full surface and half surface. In addition, heavy weight and standard weight versions are available.
Q: What differentiates the FBB heavy weight hinges from the FBB standard weight hinges?
A: FBB heavy weight hinges are equipped with four ball bearings whereas the FBB standard weight hinges are equipped with two. Heavy weight bearing assemblies employ an anti-friction sleeve that provides positive lateral support not found in standard weight assemblies. Heavy weight options are also manufactured using a thicker gauge metal.
Q: What knuckle designs are FBB hinges offered in?
A: FBB hinges are only available in a 5 knuckle design.
Q: What is the common FBB hinge application?
A: The FBB Series consists of standard commercial grade door hinges. This makes them an ideal fit for wood and metal doors, medium to heavy weight doors and medium to high frequency usage applications. In addition, ferrous and non-ferrous hinges are available. Ferrous hinges are a good fit for interior applications whereas non-ferrous hinges are ideal for exterior or corrosive environments.
