GRI 4473 Series 3/4" Recessed Contact for Wood/Aluminum/Vinyl

GRI 4473-W Recessed Contact for Wood/Aluminum/Vinyl Doors

Overview

The GRI 4473-W is a 3/4" recessed contact designed for seamless integration into wood, aluminum, and vinyl door frames. This surface-mount-compatible contact is engineered for access control and door monitoring applications where aesthetic integration and reliable operation are required. The 4473-W provides consistent door position sensing across multiple door material types, making it a versatile choice for mixed-material facility deployments.

Key Features

• 3/4" form factor optimized for standard door frame applications
• Compatible with wood frame installations
• Compatible with aluminum frame installations
• Compatible with vinyl frame installations
• Recessed mounting design minimizes visual intrusion
• Reliable magnetic switch operation for door position detection
• Standard electrical connections for integration with access control panels
• Durable construction rated for high-cycle door operation

Integration & Compatibility

The GRI 4473-W integrates directly with standard door monitoring circuits in access control systems. The contact operates as a magnetic reed switch, providing normally-open (N.O.) operation for door-ajar detection and alarm integration. Installation requires coordinated placement with a magnetic actuator mounted on the door itself, allowing the system to detect door open/close status in real time. The recessed design accommodates frame profiles typical in commercial and institutional facilities.

Deployment Recommendations

The 4473-W is commonly deployed in facilities requiring discrete door monitoring across multiple door types. The 3/4" dimension supports installation in standard door frame rabbets, reducing the need for frame modification. Technicians should verify frame material compatibility during site survey—wood, aluminum, and vinyl frames have different mounting surface characteristics. Ensure the magnetic actuator is mounted at precisely the correct standoff distance to guarantee consistent contact closure across the full door swing range. The recessed form factor is particularly suited to environments where aesthetics and security integration must coexist without visible hardware proliferation.

The GRI 4473-W (often searched as 4473 W) complies with standard electrical specifications for access control door switches and is suitable for both new installations and retrofit applications where door monitoring infrastructure requires upgrade or expansion.

Jerry Tildsen

During access control system planning across mixed-material facility portfolios, the GRI 4473-W recessed contact offers a practical solution for standardizing door monitoring across wood, aluminum, and vinyl frames. I've specified this product in environments where discrete hardware presence was required but door position reporting to the security panel was non-negotiable.

Technical Highlights:

• Multi-Material Compatibility: The 4473-W frame compatibility spans wood, aluminum, and vinyl—a valuable feature when upgrading existing facilities or standardizing across leased properties with varying door construction.
• Recessed Form Factor: The 3/4" recessed design integrates into standard frame profiles without requiring custom cutouts or frame reinforcement, reducing installation labor and minimizing aesthetic impact.

Deployment Considerations:

• Frame material verification is critical during the site survey phase. Wood frames require different fastener types than aluminum or vinyl, and surface finish preparation affects long-term contact reliability.
• Magnetic actuator positioning is the single most important installation variable. I recommend using a standoff gauge during installation to ensure consistent door-switch distance across all units in the facility.

For integrators managing multi-site deployments with heterogeneous door types, the 4473-W simplifies inventory management and reduces training complexity by consolidating door contact specifications. Pair it with a quality access control panel circuit designed for N.O. contact input, and you have a robust monitoring foundation.
