George Risk Industries 20RS 3/8-Inch Recessed Stubby Closed-Loop Contact

Provide concealed open/close monitoring for doors, windows, cabinets, and access panels with a 3/8-inch recessed magnetic contact. Its stubby body installs within a drilled mounting opening rather than on the surface of the protected frame. This approach keeps the sensing hardware less visible while preserving a clean finish on residential, commercial, and light-security installations. The closed-loop contact supports supervised alarm-loop wiring where opening the protected point changes the circuit state at the control panel. A 12-inch lead length gives installers wire for splicing within the frame, wall cavity, or nearby junction point. The white housing is appropriate where the contact must blend with painted wood, light aluminum, vinyl, or similar light-colored mounting surfaces. George Risk Industries 20RS-12-W is the specific recessed stubby configuration for applications requiring a 3/8-inch contact body, closed-loop operation, and attached 12-inch leads. Select it when the opening can accept a recessed sensor and the protected device needs a compact contact rather than a surface-mounted housing. Pair the contact with the corresponding magnet placement on the moving door, window, or panel so the circuit changes when the opening moves away from its secured position.
