Pivots
Frequently Asked Questions
What are pivots?
Pivots are door hanging hardware that carry the weight of a door at the floor and header rather than on hinges. This allows heavy or tall doors to swing smoothly. At National Lock Supply, we supply offset and center-hung pivots for storefront and architectural doors.
How do pivots differ from standard hinges?
Unlike butt hinges that mount on the door edge, pivots transfer the door’s weight to the floor and top frame, reducing frame stress and allowing for heavier or wider doors. They are often used where hinges would wear out too quickly.
What types of pivots exist?
The main types are offset pivots (shifting the pivot point away from the jamb) and center-hung pivots (allowing balanced swing in both directions). Intermediate pivots are also used on tall doors for extra support.
Where are pivots commonly used?
They are standard in storefront glass doors, aluminum entrances, and heavy architectural wood or metal doors, especially in high-traffic commercial spaces.
Are pivots ADA compliant?
Yes, when paired with door closers adjusted to ADA force requirements. Pivots allow smoother swing than standard hinges, helping accessibility.
What materials and finishes are available?
Common finishes include Aluminum, Satin Chrome, Stainless Steel, and Dark Bronze, matching storefront hardware.
Are pivots UL rated?
Yes, many pivot sets are UL-listed for fire-rated openings, making them suitable for fire-rated glass and metal doors.
How much weight can pivots carry?
Heavy-duty pivot sets can carry doors weighing 500 lbs or more, depending on model and configuration.
Do pivots require special door prep?
Yes, most pivots require floor cutouts or header prep for proper anchoring, unlike surface-mounted hinges.
