PDQ 7101 Commercial Door Closer – BC PA Mount Standard Tri Pack

The PDQ 7101 is a heavy-duty, surface-mounted commercial door closer designed for demanding applications where reliable, consistent door control is required. This listing covers the BC PA (Back Check, Parallel Arm) Mount Standard Tri Pack configuration — a value-oriented bundle providing everything needed for a complete parallel arm installation with integrated back check protection.

PDQ closers are a preferred alternative to restricted-brand lines, offering stable product design and straightforward part-level serviceability. The 7101 series is well-suited for contractors, facility managers, and specifiers sourcing closers for new construction or replacement projects.

What Is a Parallel Arm (PA) Mount?

A parallel arm (top jamb) mount positions the closer body on the push side of the door, with the arm running parallel to the door face. This configuration is commonly specified when the closer must remain on the push side — such as glazed openings, narrow soffits, or where aesthetics demand a lower-profile appearance. The parallel arm mount allows a full 180° door swing and keeps the closer body protected from direct impact.

What Is Back Check (BC)?

Back check is a hydraulic feature that provides resistance when the door is pushed open rapidly or with excessive force — typically beginning at approximately 70–75° of opening. This cushioning action protects the door, frame, closer arm, and adjacent walls from damage caused by door impact, making it particularly valuable on high-traffic or exterior doors exposed to wind pressure.

Key Features and Benefits

• Parallel arm (PA) mount — push-side installation for glazed areas, narrow soffits, and aesthetic applications
• Back check (BC) — hydraulic cushion protects door and hardware from impact damage on rapid opening
• Tri Pack bundle — standard hardware package included for complete installation
• Suitable for standard commercial interior and exterior doors
• Adjustable closing and latching speeds via external valves
• Compatible with fire-rated door assemblies (verify listing requirements for specific opening)
• Preferred brand alternative to restricted lines — designed for long-term serviceability

Typical Applications

• Commercial office buildings, schools, and healthcare facilities
• Glazed storefront and corridor doors requiring push-side installation
• Exterior doors where back check protection is needed against wind and heavy traffic
• Replacement installations requiring a parallel arm closer with back check on existing openings
• New construction hardware sets specifying surface-mounted overhead closers
