PDQ 7101 HO Heavy Duty Door Closer - Friction Hold Open Arm (Push or Pull Side Application)

                                                                   *** Retrofits LCN 4040XP and 4041 closer (Same Hole Pattern & Closer Arms) ****

The PDQ 7101 HO is an industrial-grade Surface Mounted Door Closer specifically engineered for high-traffic commercial environments that require the flexibility of a Friction Hold Open Arm. Certified to ANSI/BHMA Grade 1 standards, this closer is built to withstand over two million cycles in demanding settings like schools, office buildings, and retail outlets. A primary advantage of the 7101 HO is its retrofit compatibility with LCN 4040XP and 4041 closers; it utilizes the exact same mounting hole pattern and closer arms, allowing for a high-performance hardware upgrade without the need for new door preparation or drilling.

Designed for versatile installation, the Friction Hold Open (HO) arm allows the door to be held at a specific angle, making it an essential accessibility and convenience solution for facilities that handle frequent deliveries or high-volume pedestrian transitions. The heavy-duty cast aluminum body and high-performance, all-weather fluid ensure that the PDQ 7101 maintains consistent closing speeds and precision control in temperatures ranging from -35°C to 49°C, providing a reliable and durable solution for both interior and exterior applications.

Friction Hold Open (HO) & Control Function Summary

The Friction Hold Open (HO) arm and the closer's hydraulic valves work together to provide complete user control over the door’s operation:

• Friction Hold Open (HO) Function: The arm features an adjustable friction mechanism that allows the door to stay open at a predetermined point. This is the ideal solution for doorways where hands-free access is temporarily required, such as in loading zones or hospital corridors.
• Non-Handed Versatility: The 7101 HO is designed for Push Side (Parallel Arm) or Pull Side (Regular Arm) applications, providing a single-model solution for varied architectural needs.
• Adjustable Backcheck (BC): This hydraulic feature provides a "cushion" during the opening cycle, starting at approximately 70°. It prevents the door from being flung open with enough force to damage the wall or the closer arm itself.
• Adjustable Sweep and Latch: Independent valves allow for precise calibration of the closing speed (Sweep) and the final few inches of travel (Latch) to ensure the door closes firmly and quietly.

Engineered Solutions for Efficient Facility Operations

The PDQ 7101 HO is designed to solve the most common logistical and maintenance challenges in commercial infrastructure:

• Seamless LCN Retrofitting: Maintenance departments can save hours of labor by swapping out failing LCN 4040XP or 4041 units with the PDQ 7101. Since the footprints match exactly, there is no need to patch old holes or weaken the door with new ones.
  
• Improved Traffic Flow: The Hold Open arm is a critical solution for "peak-time" traffic. It allows staff to keep doors open during shift changes or equipment moves without using unapproved wedges or floor stops that can damage door hinges.
• ADA Accessibility Compliance: With an adjustable spring range of Size 1 to 6, this closer can be fine-tuned to meet Americans with Disabilities Act (ADA) guidelines for opening force (5 lbs maximum for interior doors), ensuring easy access for all users.
  
• Fire Safety Integrity: While the arm holds the door open for convenience, the closer is UL listed for 3-hour fire doors. Note: Friction hold-open arms should not be used on fire-rated doors unless integrated with a smoke detection system; however, the closer body itself maintains the highest fire safety rating.
  
• All-Season Hydraulic Stability: Unlike standard closers that require frequent seasonal adjustments, the PDQ 7101 utilizes stable fluid that ensures the door won't slam in the heat of summer or fail to latch during freezing winters.
