Not sure which you need?

Fire rated — Used on doors that form part of a fire-rated assembly: stairwells, corridors, garage-to-house. Fire doors usually carry a metal label on the door or frame edge.

Non-removable pin (NRP) — Does the door swing outward? Then its hinges are on the outside, and so are the pins — reachable while the door is closed and locked. Take the pins out and the door comes off, lock or no lock. NRP hinges have a set screw that prevents that. It's the security version of the same hinge.

Standard — Most interior doors that swing inward and aren't fire-rated use standard hinges.

General guidance, not a code determination — confirm requirements with your architect, contractor or building official.

Key specifications

  • Stainless Steel — maximum durability plus corrosion resistance for doors in pool rooms, kitchens and coastal entries
  • Full mortise, 4-1/2" x 4-1/2" — installs flush into the cutout already in the door and the frame
  • Ball Bearing knuckles — steel bearings carry the door's weight, so a heavy door still swings freely after years of daily use
  • ANSI/BHMA Grade 2, Standard Duty — certified for the traffic level a commercial door schedule assigns
  • Three hinges per pack in Satin Stainless Steel (US32D)
  • Non-removable pin (NRP) option — on an outswing door the pin cannot be tapped out from the outside

A 4.5" x 4.5" full mortise commercial butt hinge in stainless steel, with ball bearings, finished in Satin Stainless Steel US32D. Made for the doors a building opens all day — offices, schools, storefronts and corridors.

Why this one

Standard Weight at 0.134" thick and certified Grade 2 — sized for an interior commercial door rather than a main entrance.

The ball bearings sit in the knuckles where you can see them, and they carry the door's weight instead of letting the barrel grind on itself. On a door that opens hundreds of times a day, that is the difference between a hinge that still swings freely in five years and one that squeals.

What to check before you order

The weight class. Standard Weight suits an interior commercial door. For a full-size or solid-core door on a main opening, step up to Heavy Weight.

The prep. Full mortise, square corners, template (arc) screw pattern — it installs flush into the cutout already in the door and frame, with four screws per leaf.

The option. This hinge is offered as Standard, with a Non-Removable Pin, or Fire Rated. Choose the non-removable pin for an outswing door, where the pin could otherwise be tapped out from the outside; choose fire rated for a door that has to hold a rating at inspection.

Sold three hinges to a pack, the standard count for one door, all in Satin Stainless Steel US32D. Certified to ANSI/BHMA A156.1 and A156.7.

For use on medium-weight doors that have medium to high frequency service. Stainless steel is perfect for facilities requiring anti-rust hinges, such as medical, pharmaceutical, saunas or pool areas. Fit for commercial or residential application.

  • All hinges are individually wrapped to protect the finish and packed 3 hinges per box:
  • (24) Twenty-four wood screws (1-¼ x 12)
  • (24) Twenty-four machine screws (1/2×12-24)
