GN 315.1 Snap Locks by Elesa feature an integrated retaining pawl (with a width of 7mm), which enables its locking function. This pawl is triggered radially by means of a spring. By the press of a button, and because of the spring's provided pressure, the pawl is then disengaged. The pawl, as well as the knob, is manufactured out of a techno-polymer material, and is finished off with an RAL black color, as well as a matte polish.
