A spring hinge replaces a standard butt hinge and returns the door to the closed position on its own, using a coiled spring housed inside the barrel. Tension is set after installation by winding the spring with a hex key and dropping a locking pin into the barrel, so the closing force can be tuned to the weight of the door and the resistance of the latch.

This size is the common commercial leaf dimension used on hollow metal doors and frames with square-corner mortises. Spring hinges are normally installed in sets, with the remaining hinge locations filled by matching plain-bearing hinges, or with two or three spring hinges on heavier leaves that need more closing power.

Self-closing hinges are the usual way to make a door latch every time without hanging a surface-mounted closer on it, which keeps the hardware out of sight on stairwell, corridor and utility openings.

Key Features

• Spring-loaded barrel returns the door to the closed position without a surface closer
• Closing tension adjusted after hanging with a hex wrench and locking pin
• Square-corner leaves suited to mortised hollow metal doors and frames

• Can be installed in multiples on one leaf to increase closing force on heavier doors
• Sold by the pack
