Introduction

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.

Aesthetics

• Offset or center hung pivot sets are more attractive than alternative door hanging devices.
• Full floor-to-ceiling concealment is offered for center hung doors providing almost unlimited design flexibility.
• Extended spindles available to raise door above finished floor for complete concealment.
• Specification of heavy panels for door face with standard offset pivot preparation is available.
• Doors up to 1,750 pounds are accommodated, allowing all standard and heavy doors in a building to be hung by same hanging means.

Performance

• Full weight of door is borne by floor pivot, providing long pivot life and trouble-free operation.
• Screws are in shear in pivot-set installations and are less likely to pull out from tension–eliminates sagging doors.
• Vertical adjustment provides for field modifications to suit conditions

Safety & Security

• Models are available for labeled fire and lead-lined doors.
• Doors cannot be removed by vandals.
• Virtually concealed, pivots are not abuse or vandal prone.
• All offset pivots shall be UL10C compliant.

Economy

• Pivots provide longer life and more trouble-free operation than other door hanging means.
• Door and frame life is lengthened.

Suggested Specification

All pivots and/or pivot sets shall be the product of one manufacturer. Sets as noted in hardware groups shall be matching in design for both labeled fire doors, lead-lined doors and regular doors. Pivots for 20-minute fire doors shall be non-ferrous and match the finish of adjacent hardware. All pivot sets are required to meet ANSI grade one standard as listed in ANSI 156.4. Caps shall be hex type to increase security.

Questions and Answers
Q: I am looking for a center pivot to accommodate an unusually wide custom wood entry door, 5’W x 7’H, for our new office building we shall be moving into end of next month. Can you please send me a spec on what you would recommend. Look forward to your timely response. FYI – the wood door will be between 300 – 400#, 3” thick. We also need a closer. I was thinking either a floor or concealed closer – please let me know which one would be the best option to go with for our entry door application.
A: The short answer is this pivot:

While this pivots specifications, when reviewed, indicated Door Sizes up to 4'0" x 8'6" , I have sold this pivot dozens of times where client has used it on 5/0 wide and wider doors. It is my belief the weight rating of the pivot of 1,000 lbs is what allows the hardware to handle applications outside of the hardwares designed performance envelope.

The issue of a door closer becomes more complicated because I do not have experience where there are successful installations of floor closers on 5/0 wide doors. Everything in the Rixson book seen here:

limits us to 4/0 wide and a failure of the unit would not allow us any recourse with the factory.

My opinion is H28 seen on page 21 in the above link would likely handle to job, but I am not in a position to give you anything more concrete than my opinion.

Anything for 3" thick doors would be factory order which is typically 4 - weeks.

Please let us know if there is anything else we can help with.
