George Risk Industries Inc. 400WG-G Surface Contact Wood Gray

Product Description

The GEORGE RISK INDUSTRIES INC. 400WG-G is a commercial hidden terminal surface contact designed for use in wood door and frame applications. Surface contacts are security detection components that signal an alarm panel when a protected door, window, or access point is opened. This unit is finished in gray, allowing it to blend with standard door and frame trim in commercial environments. It is typically installed by security technicians or low-voltage electricians as part of a commercial intrusion detection or access control system.

The 400WG-G is suited for commercial and light industrial installations where a concealed or low-profile contact point is required on wood surfaces. Its hidden terminal design reduces visible wiring at the contact face, making it appropriate for finished interior spaces. This component is sold individually and is intended for professional installation in surface-mount contact applications.

Key Features

• Hidden terminal design reduces exposed wiring at the contact surface
• Gray finish suited for standard commercial door and frame trim
• Designed for surface mounting on wood door frames
• Commercial-grade construction for intrusion detection and access control systems

Installation Notes

Installation should be performed by a licensed low-voltage electrician or certified security technician in accordance with applicable local codes and NEC low-voltage wiring requirements. Disconnect and de-energize the alarm panel or control loop before installing or servicing surface contacts. Mount the contact and magnet in proper alignment per the manufacturer data sheet to ensure reliable actuation. Do not overtighten mounting hardware into wood frames, as this may crack the contact housing or shift alignment.
