GRI 4405-A Industrial Surface Mount Switch Set

The GRI 4405-A Industrial Surface Mount Switch Set is a heavy-duty magnetic contact solution engineered for demanding commercial, industrial, and perimeter security applications. Manufactured by George Risk Industries (GRI), this rugged surface mount contact is designed to provide reliable door and gate monitoring in environments where durability, wide gap tolerance, and long-term performance are critical. Ideal for overhead doors, metal doors, fences, gates, warehouses, and industrial facilities, the 4405-A delivers dependable intrusion detection performance even in harsh operating conditions.

Built with a robust extruded aluminum housing and designed specifically for surface mounting applications, the GRI 4405-A is commonly deployed in security systems requiring a highly visible, industrial-grade contact solution capable of handling vibration, weather exposure, and heavy-use environments. Its versatile design makes it an excellent choice for installers, integrators, and facility managers seeking dependable perimeter protection across commercial and industrial properties.

Built for Industrial & Commercial Security Applications

The GRI 4405-A is specifically engineered for applications where standard residential magnetic contacts are simply not sufficient. Industrial and commercial environments often expose security hardware to vibration, temperature fluctuations, moisture, dust, and heavy physical use. The 4405-A is built to withstand these demanding conditions while maintaining accurate and consistent monitoring performance over time.

Its heavy-duty aluminum construction provides enhanced durability and protection, making it ideal for warehouses, manufacturing plants, distribution centers, and commercial facilities requiring reliable perimeter security. Whether installed on overhead doors, metal entry points, or industrial gates, this contact helps ensure critical access points remain continuously monitored.

Reliable Protection for Overhead & Roll-Up Doors

Overhead doors and roll-up doors present unique challenges for intrusion detection systems due to vibration, movement, and larger operating tolerances. The GRI 4405-A is designed to accommodate these environments with a dependable magnetic switch assembly capable of maintaining reliable operation even in high-cycle applications. Its surface mount design allows for straightforward installation on large doors and uneven mounting surfaces where recessed contacts may not be practical.

This makes the 4405-A an excellent solution for loading docks, shipping facilities, fleet maintenance buildings, storage facilities, and industrial garages where dependable monitoring is essential to protecting inventory, equipment, and restricted areas.

Flexible Integration with Security & Access Systems

The GRI 4405-A Industrial Surface Mount Switch Set integrates seamlessly with a wide range of commercial intrusion detection systems, alarm panels, access control platforms, and perimeter security applications. Security integrators frequently deploy these contacts alongside professional-grade systems from manufacturers such as Bosch, DSC, Honeywell, DMP, Alarm.com, Kantech, and other leading security platforms.

Its universal magnetic contact design allows the switch set to function as part of both standalone intrusion systems and fully integrated access control environments. This flexibility makes it a valuable component for both retrofit upgrades and new commercial construction projects.

Surface Mount Design Simplifies Installation

The surface mount configuration of the GRI 4405-A allows installers to secure the contact directly onto doors, frames, gates, and structural surfaces without extensive drilling or modification. This is especially beneficial when working with metal doors, concrete structures, rolling steel doors, or locations where recessed mounting is difficult or impossible.

Its visible mounting profile also serves as a visual deterrent in some security environments, helping reinforce perimeter protection while simplifying future inspection and maintenance procedures.
