PDQ 719003 Regular Closer Arm: Heavy-Duty Cast Iron Series Hardware

The PDQ 719003 Regular Closer Arm is a rugged, architectural-grade replacement arm designed specifically for the PDQ 7100 and 7101 Series heavy-duty door closers. Known as the "Iron Horse" of the industry, the 7100 series requires a specialized arm assembly capable of managing the extreme torque and high-cycle demands of institutional and high-traffic commercial environments.

This Standard Double Lever Arm is engineered to restore the precise closing efficiency of your door. Whether you are maintaining an existing opening in a school, hospital, or government building, the 719003 ensures your hardware continues to meet ANSI/BHMA Grade 1 performance standards.

Precision Hexagon Drive Interface

When replacing a Commercial Door Closer Arm, the connection point is the most critical factor. The PDQ 719003 features a distinct hexagon-shaped hole at the attachment point where the arm meets the closer pinion.

This hex-drive design is exclusive to the heavy-duty cast iron 7100 series. It provides a superior, non-slip "lock" onto the pinion, ensuring that the arm can handle the massive spring power (Sizes 1-6) of the PDQ 7101 without stripping or loosening over time—a common failure point in inferior square-drive alternatives.

Technical Specifications

Why Choose the PDQ 719003 from Doorways Plus?

At DoorwaysPlus.com, we understand that specialized hardware requires specialized knowledge. Using the correct OEM replacement part like the 719003 is vital for several reasons:

• High-Torque Performance: The forged steel construction is designed for the weight of heavy exterior and oversized doors.
• Smooth Hydraulics: Maintains the correct geometry required for your closer's Sweep, Latch, and Backcheck valves to function as intended.
• Direct Fit: Eliminates the guesswork in the field. If your closer body has a hexagon pinion, this is the exact arm required for a successful repair.
• Durability: Built to match the 25-year lifespan of the PDQ 7100 series body.

Technical Identification Note: Please verify your closer body before ordering. If your closer pinion is square-shaped, you likely have a 3100 or 5300 series unit and will require the PDQ 999003 instead. The 719003 is exclusively for the hex-pinion cast iron models.
