GRI's recessed switches are most versatile for a variety of applications, but the switch and magnet installed, should never form a "T" configuration.
When the application calls for a wide gap switch, using a bare magnet, keep in mind that GRI's bare magnets are installed with the painted end towards the switch as they are polarity sensitive. When protecting steel doors, use the GRI PA-75 collars with our wide gap switch.
2020 Series Standard Features
The G.R.I. 20RS Series recessed "shortie" switch set is designed for applications where a 3/8" press to fit set is needed but space limitations will not allow for a full length set to be installed. With the 5/8" 20RS-12, or the .930" 20RS-T, the installer is able to protect openings that otherwise would have to be secured with more visible surface mount configurations.
Available in regular and extra wide gaps, the 20RS Series provides an easy answer to the difficult, high dollar window problems every installer encounters.
