PDQ 429019 Heavy-Duty Double Door Strike for 4200 Series Rim Exit Devices

The PDQ 429019 (legacy model 429019) is a specialized, investment-cast stainless steel strike engineered specifically for mounting PDQ 4200R or 4200RF rim exit devices on a pair of doors. This hardware component is the premier solution for double door openings where a center mullion is either not present or not desired. By providing a high-strength latching point on the face of the inactive door leaf, the 429019 ensures that the active leaf remains securely closed and correctly aligned, meeting both security and life-safety requirements.

In high-traffic commercial environments like schools, retail centers, and office complexes, door alignment is the most common cause of hardware failure. This strike is a critical problem-solver that addresses those alignment issues by offering a precision-milled surface for the rim panic bolt to engage. Its heavy-duty construction is designed to withstand the daily physical impact of door closures and attempted forced entry, maintaining the structural integrity of the entire door opening without the added cost and obstruction of a floor-to-ceiling mullion.

ANSI Function Summary: Double Door Rim Latching Solution

The PDQ 429019 serves as the primary latching interface for rim-type panic hardware in non-mullion double door configurations.

• Inactive Leaf Latching: On a pair of doors, the rim exit device on the "active" door requires a strike to latch into. The 429019 is surface-mounted to the "inactive" door leaf, creating a secure, reinforced pocket for the exit device's pullman latch.
• Fire-Rated Integrity: When paired with the PDQ 4200RF (Fire Rated) series, this strike is a key component in maintaining a 1-1/2 to 3-hour fire rating. It ensures "positive latching," keeping the doors closed against the pressure of a fire to prevent the spread of smoke and heat.
• Security Deadlocking: The strike's geometry is specifically contoured to work with the 4200 Series deadlocking latch bolt, preventing "loiding" attacks where a tool is used to manually retract the bolt from the exterior.

Solutions for Double Door Hardware Reliability

The PDQ 429019 Double Door Strike addresses several technical and regulatory challenges in facility management:

• Eliminate Door Binding: Standard rim strikes are often too bulky for the meeting stiles of double doors, causing the doors to rub or fail to close. The low-profile design of the 429019 provides a slim yet high-strength solution that allows for smooth door operation.
• Cost-Effective Security Upgrades: Installing a removable or permanent mullion can be expensive and labor-intensive. This strike allows you to achieve a high-security latching point for your panic bars at a fraction of the cost, making it ideal for retrofitting existing double doors.
• Vandal-Resistant Mounting: When installed with thru-bolts, this strike is physically clamped to the door, making it virtually impossible to pry or kick off. This provides an essential layer of protection for rear exits and delivery doors.
• Corrosion-Resistant Longevity: Fabricated from stainless steel, this strike is immune to the rust and degradation often seen with plated zinc strikes. It is suitable for exterior-facing doors and environments with high humidity or chemical exposure.
• Compliance with Life Safety Codes: This component is fully compatible with UL 305 panic hardware standards, ensuring that while the door is secure from the outside, it remains effortlessly operable for emergency egress from the inside.
