Kawneer Butt Hinges & Replacement Parts

Kawneer Storefront Door Butt Hinges

Kawneer storefront door butt hinges are designed for use on commercial aluminum entrance doors where the door is hinged directly to the storefront frame. Unlike pivot-hung entrances, a butt-hung storefront door uses multiple hinges positioned vertically along the hinge stile to support and control the door as it swings.

Because commercial storefront doors may experience hundreds or thousands of opening cycles, the hinges are critical components of the entrance system. Worn or damaged hinges can contribute to door sag, alignment problems, rubbing, improper clearances, and difficulty opening or closing the door.

Automatic Door and Hardware offers Kawneer commercial door hinges and related replacement parts for repairing and maintaining aluminum storefront entrance systems.

How Kawneer Butt Hinges Work

On a butt-hung commercial storefront door, one hinge leaf attaches to the aluminum door stile while the opposite leaf attaches to the storefront frame. The hinge barrel provides the pivot point that allows the door to swing open and closed.

Multiple hinges are typically installed vertically along the door to distribute the weight of the entrance. Maintaining proper hinge condition and alignment is especially important on commercial glass and aluminum doors because even relatively small changes in door position can affect clearances around the frame and threshold.

Clear Anodized & Dark Bronze Storefront Hinges

Commercial aluminum storefront entrances are manufactured in several common architectural finishes. Replacement Kawneer hinge options are available to coordinate with popular storefront finishes, including clear anodized aluminum and dark bronze anodized.

When replacing an existing hinge, compare the finish of the replacement hardware with the existing storefront door and frame for the best overall appearance.

Is Your Storefront Door Sagging?

A commercial storefront door that has dropped or become difficult to operate may have a problem somewhere in its supporting hardware. Symptoms can include the bottom of the door rubbing against the threshold, the top of the door contacting the frame, uneven gaps around the entrance, or difficulty latching and locking.

Butt hinges should be inspected as part of the troubleshooting process on a butt-hung door. Check for loose fasteners, excessive movement, worn hinge components, damaged mounting locations, and other conditions that could affect the alignment of the entrance.

How to Identify a Replacement Kawneer Butt Hinge

Commercial storefront hinges can look similar, so it is important to identify the existing hardware before ordering a replacement.

1. Confirm the door is butt hung. Look for exposed hinge barrels along the hinge side of the door.
2. Measure the existing hinge. Compare the overall hinge dimensions and leaf dimensions.
3. Compare the mounting hole pattern. Screw locations and mounting patterns are important when identifying replacement hardware.
4. Inspect the hinge construction. Compare the barrel, leaves, bearings, fasteners, and other visible characteristics.
5. Verify the finish. Select the appropriate finish to coordinate with the existing storefront entrance.

Replacement Kawneer Hinges for Existing Storefront Doors

A worn hinge does not necessarily mean the complete storefront door needs to be replaced. When the door, glass, and aluminum framing remain serviceable, replacing damaged hinge hardware may allow the existing entrance to remain in operation.

This makes replacement Kawneer butt hinges an important component for commercial door technicians, building maintenance departments, facility managers, glass companies, contractors, and property owners maintaining existing storefront entrances.
