Magnasphere HSS-1671-L2D-010 Overhead Door Bracket with HSS L2D-010 Pre-Mounted Left Side with Embedded EOL Resistors

Protect perimeter openings with a rugged, install-ready magnetic contact engineered for high-security overhead doors. The Magnasphere HSS-1671-L2D-010 magnetic contact combines a pre-mounted left-side HSS L2D-010 assembly on an overhead door bracket with embedded EOL resistors to deliver supervised zone monitoring and faster field wiring. Built to UL-634 Level 2 standards, this magnetic contact resists magnetic defeat and switch welding caused by lightning, power surges, or directed electromagnetic attack, making it a strong choice for demanding security, surveillance, and monitoring applications.

Installation is simplified by the cross-hole mounting design that eliminates most L- and Z-bracket needs and requires no post-install adjustment. The rugged construction and armored cable options ensure reliable operation in industrial and commercial environments, while embedded resistors make the unit compatible with most alarm control panels that accept supervised inputs. Ideal for perimeter security, access control, and integration with intrusion monitoring systems—specify the HSS-1671-L2D-010 for projects that demand proven durability and tamper resistance, or contact our team to order and configure for your installation.
