PDQ 639714 Double Door Strike for 6300R Rim Exit Device

The PDQ 639714 is a high-performance, investment-cast stainless steel strike specifically engineered for applications involving a pair of doors where a removable mullion is not used. Designed as a dedicated companion for the PDQ 6300R and 6300RF Rim Exit Devices, this strike provides a secure, precision-aligned latching point on the inactive leaf of a double door set. It is the premier solution for facilities that require wide-opening egress without the physical obstruction or added cost of a center mullion post.

Constructed for maximum durability in high-traffic commercial environments, the 639714 addresses the common challenge of latch engagement on double doors. By through-bolting directly to the face of the inactive door, it creates a rigid and formidable "sandwich" with the interior hardware, ensuring that the active door remains securely latched and deadlocked. This strike is an essential security and life-safety solution for schools, hospitals, and retail centers that must maintain a secure perimeter while accommodating large equipment or high-volume pedestrian traffic.

ANSI Function Summary: Double Door Latching Interface

The PDQ 639714 functions as the critical receiver for rim-type panic hardware in non-mullion double door configurations.

• Inactive Leaf Mounting: In a "Pair of Doors" scenario, the rim panic bar on the active door requires a surface to latch into. The 639714 is mounted to the surface of the inactive door (usually secured by manual or automatic flush bolts), acting as a stationary strike plate.
• Fire-Rated Coordination: When used with the PDQ 6300RF (Fire-Rated) exit device, this strike ensures the door assembly meets "positive latching" requirements. This prevents the doors from pulling apart under the high-pressure conditions of a fire, maintaining the fire barrier.
• Precision Deadlocking: The geometry of the strike is specifically calibrated to the 3/4" throw stainless steel latch of the 6300 Series. This ensures the deadlocking feature of the panic bar engages correctly, preventing "loiding" or shim attacks from the exterior.

Professional Solutions for Hardware Alignment and Security

The PDQ 639714 Double Door Strike is designed to solve several architectural and maintenance pain points:

• Eliminates Door Interference: Traditional strikes can be too thick for the meeting stiles of double doors, leading to binding. The 639714 features a low-profile design that maximizes latch engagement while allowing the doors to swing freely without rubbing.
• Structural Reinforcement: Because double doors are more susceptible to being forced open than single doors, this strike is through-bolted for maximum pull-out resistance. It distributes the force of an attempted breach across the entire door thickness rather than just the surface skin.
• Retrofit Simplified: This strike allows for a high-security upgrade on existing double doors where the installation of a floor-to-ceiling mullion is physically or financially impractical. It provides a clean, professional appearance that covers old mounting holes.
• Corrosion and Impact Resistance: The investment-cast stainless steel construction ensures the strike will not crack under heavy impact from carts or equipment and will not rust in exterior or high-humidity environments.
• Code Compliance Assurance: Using a strike specifically tested and listed for the 6300 Series ensures that your door assembly remains compliant with UL 305 and UL 10C standards, avoiding issues during Fire Marshal inspections.
