Hey guys, this is Gary with Door Closers USA. In today’s video, we’re going to cover how to replace anoffset pivot hinge on a commercial storefront glass door.
This is the most common hinge system used on storefront doors. Because these pivots are surface-mounted,they’re also one of the most frequently serviced components on commercial glass doors.
A storefront offset pivot system consists of both a top pivot and a bottom pivot.These components work together to carry the full weight of the door while allowing it to swing smoothly.
The upper pivot includes a spring-loaded pin that inserts into a bushing mounted inside the frame.This assembly consists of two main parts:
The bottom pivot typically mounts inside the frame and through the threshold.The door portion contains a bearing that allows the bottom pin to rotate smoothly.
In proper installations, the bottom pivot should always be supported from below, such as with a concrete slab,shims, or a 2x6 blocking underneath.
Although storefront doors may look identical, pivot hinges are not universal.Each door manufacturer uses specific pivot designs and hole patterns.
Check the bottom rail of the door or the side of the frame. Many doors have the manufacturer stamped there.Common brands include:
If the door is older and no branding is visible, sometimes the lock cylinder or faceplate may provide clues.
If the door manufacturer is unknown, matching the screw hole pattern is the most reliable method.
By comparing these hole patterns, we can identify the exact pivot model required.If needed, simply send us photos and we can match it for you.
Another critical detail when ordering pivot hinges is determining whether your door isflush or 1/8" recessed.
Using the wrong pivot style can cause misalignment issues, requiring strike adjustments or causingpoor door operation.
Before replacing the pivots, the door must be removed safely.
Important: Always support the door’s weight during removal to avoid damage or injury.
If frame screws are inaccessible, you can carefully drill through the top pivot housingto depress the spring-loaded pin and release the door.
Pivot hinge kits include both door-mounted and frame-mounted components.
Most pivot hinges are handed, so be sure to verify left-hand or right-hand orientation.
Always test the lock operation before leaving the job site.
Pivot hinges should be replaced if you notice:
In many cases, these symptoms are mistaken for weatherstripping issues,when the real problem is worn pivot pins and bushings.
