N1178T SHK

1” RECESSED STUBBY DOOR CONTACT WITH SHARK MAGNET

Nascom’s N1178T SHK Series is a 3/4” recessed stubby door contact couple with the patented SHARKTM magnet. The set is designed for residential, commercial and industrial steel and wood door applications.

The N1178T SHK is the installer’s choice of contact configuration because the contact set is designed to cut installation times .. just a pinch of the springs installs the SHARKTM magnet permanently and the powerful rare earth magnet helps to prevent false alarms caused by shifting or warping doors.
