The G.R.I. 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, wide and extra wide gaps, the 20RS series provides an easy answer to the difficult, high dollar window problems every installer encounters. *Note: Some versions are special order and can take up to 30 days to ship.
