Commercial Self-Closing Door Hinge | US26D Satin Chrome or US32D Satin Stainless Steel

Add reliable self-closing action to commercial door openings with the Vector Hinge Co. 4.5" x 4.5" Spring Hinge, designed for commercial and institutional doors where automatic closing is required or preferred.

The internal spring mechanism applies closing force directly through the hinge, helping return the door toward the closed position after use. Its compact design provides a clean alternative to a surface-mounted closer for compatible applications.

Available in US26D Satin Chrome or US32D Satin Stainless Steel to coordinate with common commercial architectural hardware.

Selecting the Correct Quantity

The number of spring hinges required depends on the complete door assembly.

Consider:

• Door weight

• Door width

• Door height

• Required closing force

• Existing hinge quantity

• Latching resistance

• Air pressure at the opening

Do not assume one spring hinge will provide sufficient closing force for every commercial door.

Fire-Rated Door Applications

A spring hinge does not automatically make a door opening fire rated.

When used on a rated opening, the complete assembly—including the:

• Door

• Frame

• Hinges

• Latching hardware

• Closing hardware

• Other required components

must comply with the applicable listing, installation instructions, and code requirements.

Installation Notes

Before ordering, verify:

• 4.5" x 4.5" hinge preparation

• Existing screw-hole pattern

• Door thickness

• Door weight

• Door width

• Number of hinges required

• Required spring tension

• Required finish

• Fire-rating requirements, if applicable

Proper door alignment is important for consistent self-closing operation.
