Complete or repair a compatible overhead concealed closer installation with the Prime Door Controls 7000 Series OHC Type G Bottom Center Pivot.

Type G Pivot Configuration

The Type G is a floor-mounted bottom pivot used with compatible center-hung overhead concealed closer systems.

Typical Type G characteristics include:

• Floor mounting

• Center-hung door configuration

• Side-load arm application

• 1-1/2" deep bottom rail

• Adjustable door height

This configuration differs from threshold-mounted pivots such as the Type GE and Type AE.

Floor-Mounted Design

Unlike a threshold-mounted pivot, the Type G installs directly into the floor beneath the door.

This makes it suitable for compatible openings where the door hardware system is designed around a floor-mounted bottom pivot.

The floor mounting provides the lower rotational point required for the center-hung door system.

1-1/2" Bottom Rail Application

The Type G configuration is designed for doors with approximately a:

1-1/2" deep bottom rail

Always verify the existing door extrusion and pivot preparation before ordering.

The bottom-rail depth is an important compatibility dimension and should not be assumed based solely on the appearance of the existing pivot.

Side-Load Application

The Type G pivot is commonly paired with compatible side-load top-arm configurations.

For a complete OHC system, the door may use:

• Prime 7000 Series OHC closer body

• Side-load top arm

• Type G floor-mounted bottom pivot

The top arm, bottom pivot, rail depth, and closer spindle must all match the door preparation.

Adjustable Door Height

Type G pivots typically provide approximately 3/16" of vertical adjustment.

This allows installers to fine-tune:

• Door height

• Header clearance

• Bottom clearance

• Door alignment

• Proper engagement with the top arm and closer

Proper adjustment can help correct minor alignment issues after installation.

Recommended Door Capacity

Typical Type G pivot specifications recommend use on doors weighing up to approximately:

125 lb

Actual allowable door weight depends on the complete closer, pivot, arm, door construction, and manufacturer requirements.
