Center Hung Pivots Notes
diagram_center_hung
The pivot point is centered in the door width.
This allows the door to swing both ways (double acting) if needed.
Notice how the door edge is beveled in both direction to allow the double action.
Double acting doors require a frame with no stop, which is called a cased opening. Sometimes these pivots are used on doors that swing but a single direction (single acting). In these cases, a stop is applied to the top of the frame and the latching edge of the frame. The stop simply prevents the door from swinging both directions.
Most of the hardware is concealed in center hung applications. Therefore, finish is not as important as with other hardware types.

Model Numbers
Rixson model numbers make no sense. Don’t try to figure them out.
For example, model 117 is an offset pivot who’s offset is 3/4”, but model 117-3/4 is not offset at all. It is a center hung model. So when you see ”3/4” within a model number don’t think it has any significance.
Rixson manufacturers high quality products that last a long time. They just were asleep at the wheel when it came time to assign model numbers to them.

General Pivot Notes
Pivot sets provide the best possible means of hanging a door. They are designed to work with the laws of physics to provide long-lasting performance and reliability.
The weight of the door is supported entirely by the bottom arm, which is directly connected to the pivot spindle. This hanging means provides several important advantages:
• Fasteners on the door and frame are in shear rather than tension (as with hinges) and are less likely to pull out overtime. This creates less stress on the frame assembly, prevents door sagging and allows the door to swing with less resistance from friction.
• A door supported in this manner relies on the strength of the floor to carry the weight, not the frame. This allows extremely heavy doors to be hung in an opening and allows door adjustment throughout the life of the building to compensate for settlement.
