PDQ 3100 Series Commercial Door Closer – Tri Pack (BC/PA)

The PDQ 3100 Series Commercial Door Closer is a heavy-duty, surface-mounted hydraulic closer engineered for high-traffic commercial openings. The Tri Pack configuration includes mounting hardware and templates for both regular arm (BC – back check) and parallel arm (PA) installations, giving contractors and facilities teams maximum flexibility on a single SKU. Whether you are replacing a worn closer on an office corridor, specifying hardware for a new school or healthcare facility, or maintaining a fire-rated opening, the PDQ 3100 delivers reliable, code-conscious door control.

Key Benefits

• Flexible Tri Pack mounting – supports regular arm with back check and parallel arm mounting from one box, reducing jobsite inventory and simplifying procurement
• Hydraulic back check (BC) – cushions the door on opening to protect the door, frame, and adjacent walls from impact damage
• Parallel arm (PA) option – ideal when the closer must be mounted on the push side or when header space is limited; note that parallel arm mounting typically requires one size larger spring for equivalent closing force
• Adjustable closing and latching speed – field-adjustable valves allow the installer to fine-tune door speed to meet ADA sweep-speed requirements and local code
• Commercial-grade construction – suited for interior and select exterior applications in office buildings, schools, healthcare facilities, retail, and institutional environments
• PDQ brand stability – PDQ is a preferred line for service-friendly, part-stable commercial hardware, reducing the risk of obsolete components over the product lifecycle

Typical Applications

• Office and corridor doors requiring controlled latching
• School and university interior doors
• Healthcare and institutional facility doors
• Retail and light commercial entry doors
• Fire-rated door assemblies requiring a self-closing device (verify UL listing with current product documentation)
• Replacement closer projects where back check or parallel arm mounting is specified

Installation & Specification Notes

When mounting in parallel arm configuration, the closer body is installed on the door's push side with the arm running parallel to the door face. This reduces exposure of the closer body and arm to weather and abuse on exterior doors. Per industry guidance (ANSI/BHMA A156.4), parallel arm and track arm installations typically result in a reduction in effective closing force — specify one closer size larger than the standard recommendation for regular arm when using PA mounting on wide or heavy doors.

The back check function engages hydraulically as the door approaches its fully open position, slowing the door before it contacts a wall stop. This protects both the hardware and the surrounding structure and is strongly recommended for high-traffic or wide-swing openings.

Technical Details

Note: Verify current UL/fire listing, spring size range, and finish options with the current PDQ 3100 Series product specification sheet. DoorwaysPlus can also quote comparable alternatives from preferred closer lines including Hager, Norton, Accentra (formerly Yale), and Corbin Russwin if your project requires a different specification.

The PDQ 3100 BC PA Door Closer is a commercial-grade solution designed for reliability and ease of installation. Engineered to meet ANSI/BHMA A156.4 Grade 1 standards, this closer is ideal for medium-traffic environments such as offices, retail storefronts, and assisted living facilities.

What sets the 3100 series apart is its Tri-Pack mounting capability. Whether you require a Regular Arm, Top Jamb, or Parallel Arm installation, this single unit handles it all. Featuring adjustable backcheck (BC) to prevent the door from slamming into walls, the PDQ 3100 ensures both user safety and structural longevity.

Key Performance Features

• Adjustable Spring Power: Factory preset to Size 3, but easily adjustable from Size 1 to 6 to handle doors of various weights and widths.
  
• Dual Valve Control: Separate valves for Sweep and Latch speed allow for precise closing transitions.
  
• Non-Handed Design: Simplifies ordering and installation—works on both left and right-hand doors.
  
• Cast Aluminum Body: Provides a high strength-to-weight ratio with excellent corrosion resistance.
