Type AE Pivot Configuration

The Type AE is a threshold-mounted bottom pivot designed for compatible center-hung overhead concealed closer systems.

Industry Type AE specifications identify this configuration for:

• 1" deep bottom rails

• Threshold mounting

• Center-hung doors

• End-load hardware applications

• Doors up to approximately 175 lb

Always verify the complete door and closer configuration before ordering.

Center-Hung Door Application

The bottom pivot supports the lower portion of a center-hung door while the overhead concealed closer and top arm control the upper portion.

Center-hung systems are commonly used on:

• Aluminum storefront doors

• Glass-and-aluminum entrance doors

• Retail entrances

• Commercial offices

• Institutional buildings

• High-traffic entrances

Threshold-Mounted Design

The Type AE pivot installs at the threshold rather than directly into the floor.

This provides the lower pivot point required for compatible center-hung door assemblies and allows the door to rotate smoothly while maintaining proper alignment.

Designed for 1" Bottom Rails

The 1" specification refers to the depth of the compatible door's bottom rail.

Before ordering, verify that the existing door has:

• 1" deep bottom rail

• Type AE pivot preparation

• Center-hung configuration

• Compatible end-load top arm

• Compatible overhead concealed closer

Pairs with End-Load Hardware

The Type AE pivot is commonly paired with the A-Type 1" End Load Arm at the top of the door.

A typical compatible system may include:

• Prime 7000 Series OHC closer body

• A-Type 1" End Load Arm

• Type AE Bottom Pivot

Matching the top arm and bottom pivot to the door rail configuration is critical for proper operation.
