Resideo 958 — a surface-mount overhead door magnetic contact with an adjustable magnet, from the Resideo high-security wired contact line.
The contact body mounts to the floor or frame and the magnet rides on the door, so the circuit changes state when the door leaves its closed position and a panel sees it. The magnet is adjustable because an overhead sectional or rolling door does not return to exactly the same place twice.

The number sits in a close family and the differences matter. Resideo titles the 958-2 as the Form C (SPDT) version of the same contact; the 959 is the XTP overhead door contact for positions exposed to moisture or corrosion; the MPS52 is a third overhead door contact in the same catalogue; and the 4959SN is the V-Plex addressable version, reporting on a polling loop rather than a conventional zone.
