The N1175W-M from Nascom is a recessed 3/8" press fit mini NdFeb neodymium grade N35 nickel plated magnet, white. The N1175 Series, mini 3/8" recessed contact, protects all nonferrous (e.g. wood, aluminum and vinyl) doors and windows, in both residential and commercial settings. The N1175 is the installers's choice of contact configuration where drill depth is critical and excellent air and side-to-side gap are required to prevent false alarms caused by shifting or warping doors and windows.
