ADT Door/Window Sensor Spacers (Door/Window Sensors are not included, and are sold separately) help offset deep door or window molding when setting up our Door/Window Sensors so that Door/Window sensor and magnet are no more than ½” apart when the door or window is closed. The spacer adds height to the sensor or magnet piece to help ensure the two are level for proper function. The thin plastic pieces fit under the sensor and/or magnet, and you can stack multiple spacers together to achieve the height needed for your molding. Each 4-pack includes 4 spacers for the sensor and 4 spacers for the magnet (8 total pieces). Dimensions: Door/Window sensor spacer: 76 mm x 23.5 mm x 3.95 mm (thickness includes double-sided tape) Door/Window sensor magnet spacer: 43 mm x 15.3 mm x 3.95 mm (thickness includes double-sided tape).
