Miller Sensing Edge MGS20 / MGR20 – 3-Sided Safety Edge for 2" Gate Posts
The Miller Sensing Edge MGS20 (square post) and MGR20 (round post) are 3-sided safety edges designed for motorized slide and swing gates. They provide added protection by wrapping around the leading edge of the gate and instantly signal the operator to stop or reverse upon contact.
These edges mount directly to a 2" post — no mounting channel required — making installation fast and clean.
