Nascom N505AU/STK N505AU Universal Flip Set with 1913 Bracket and Screws

For reliable man-door protection and uninterrupted access control, the Nascom N505AU/STK Universal Flip Set delivers field-ready performance. This magnetic contact set combines Nascom engineering with a flip-mount option so installers can run the cable in either direction without compromising the gap — reducing install time and site rework. Built for security and surveillance systems, the N505AU uses a powerful N35 NdFeB magnet and a 2.75" standard gap to ensure consistent door state detection, while the No Dead Spot closed-loop contact reduces nuisance alarms caused by door misalignment.

Rugged construction includes an extruded anodized aluminum body and armored cable lead protection to resist tampering and environmental wear. Each kit ships with a universal 1913 L-bracket, screws and 36" 22 AWG wire leads to speed deployment in access control, monitoring and alarm applications. Whether upgrading perimeter doors or specifying components for a new security system, the Nascom N505AU magnetic contact offers dependable performance and easier installs.
