The George Risk Industries 2020-T-W is a recessed contact with a press-fit terminal designed for low-voltage security and alarm system wiring. The unit features a 3/8-inch diameter body that installs into a drilled or pre-bored hole, creating a flush, concealed mount point for door and window sensing applications. A 1/2-inch terminal accommodates the press-fit wire connection, eliminating the need for screw terminals in tight installation spaces. This component is sold individually and is installed by alarm system technicians, electricians, and security integration professionals.
This recessed contact is suited for residential and light commercial security installations where a concealed sensor profile is required. Common applications include wood or hollow-core door frames, window frames, and cabinet doors where surface-mount hardware is not desirable. The white finish allows the unit to blend with painted trim and standard door frame finishes. Its compact 3/8-inch body diameter makes it compatible with standard drill-bit sizing used in security rough-in work.
Designed as an OEM-style replacement or new-installation recessed contact for low-voltage security and alarm system applications requiring a 3/8-inch press-fit terminal sensor.
Installation is typically performed by licensed alarm technicians or low-voltage electricians following applicable local codes. Disconnect or power down the alarm control panel before wiring any contact. Bore the mounting hole to the correct diameter to ensure a secure press fit and confirm the terminal connection is fully seated before closing the door or window frame. Avoid forcing the body into undersized holes, as this may damage the terminal leads.
