PDQ 6310RF 48" Heavy-Duty Fire-Rated Rim Exit Device - Grade 1 Wide Stile

The PDQ 6310RF is a premier, Grade 1 Fire-Rated Rim Exit Device specifically engineered for oversized 48-inch (4-foot) fire door openings. This institutional-grade hardware is the ultimate solution for high-occupancy environments—such as hospital main corridors, university auditoriums, and convention centers—where maintaining a certified fire barrier is as critical as ensuring effortless egress. Built with a reinforced investment-cast steel chassis and heavy-duty stainless steel latching, the 6310RF provides a formidable defense against forced entry while adhering to the strictest life-safety codes.

As a high-performance fire safety solution, the 6310RF is designed to prevent "door-peel" and latch failure during extreme thermal events. Its patent-pending "cush-spring" technology delivers whisper-quiet operation, making it ideal for healthcare and educational settings where noise reduction is a priority. This device is not just hardware; it is a long-term infrastructure investment designed to eliminate the sagging and mechanical fatigue often seen in standard-duty devices on wide 4-foot doors.

ANSI Function Summary: Fire-Rated Rim Exit Hardware

The PDQ 6310RF is categorized as Fire Exit Hardware, meaning it is specifically designed to provide "positive latching" for fire-rated door assemblies.

• Fail-Safe Positive Latching: In accordance with NFPA 80 and UL requirements, this fire-rated device does not include a dogging feature. The latch remains active at all times to ensure the door stays latched during a fire, preventing the spread of smoke and flames.
• Effortless Egress: Despite its heavy-duty fire rating, the touch bar requires minimal force to operate. Occupants can exit in a single motion by pushing the bar at any point, satisfying all ADA and emergency exit regulations.
• Deadlocking Security: The stainless steel pullman-style latch bolt features a deadlocking trigger. Once the door is closed, the bolt is mechanically locked in place, preventing "loiding" or shimming attempts from the exterior.

Technical Specifications

Professional Solutions for High-Traffic Fire Openings

The PDQ 6300 Series solves the most common durability and compliance challenges for facility managers:

• Engineered for 4-Foot Doors: Standard exit devices often flex or fail when installed on wide 48" doors. The 6310RF utilizes an extruded aluminum rail reinforced by a cast chassis, ensuring the bar remains level and the latch stays aligned over years of heavy use.
• Quiet-Operation Technology: The internal cushion system eliminates the metallic "clanging" typical of traditional panic bars. This provides a quieter environment for patients in hospitals or students in testing centers.
• Vandal-Resistant Design: Featuring heavy-duty flush end caps that key directly into the rail, the device is built to resist prying and impact from carts or equipment, significantly reducing maintenance costs in high-abuse zones.
• Severe Weather Rated: Certified for High Velocity Hurricane Zones (HVHZ), this device provides exceptional structural integrity against extreme wind loads and pressure, making it a versatile choice for coastal facilities.
• Domestic Sourcing Compliance: Assembled in the USA, this hardware meets the requirements of the Buy American Act (BAA) for federal and municipal government projects.
