The MAGNASPHERE CORP HSS-1451-L2S-011 is a rollup door bracket kit configured for left-side premount installation. Bracket kits in this category are used to mount sensing or alarm hardware to rollup door frames, providing a stable, repeatable mounting position for the associated sensor or switch assembly. This kit ships as a single unit and is intended for professional installation in commercial or light-industrial door security and access-control applications.
This bracket kit is suited for rollup door installations where left-side premounting is required. Typical applications include commercial warehouses, loading docks, storage facilities, and any secured rollup door entry point where a sensor or switch must be precisely positioned. It is generally installed by security system technicians, electricians, or door hardware professionals during initial system setup or replacement service.
Designed as an OEM-style mounting bracket kit for rollup door sensor and switch assemblies requiring a left-side premount configuration. No specific compatible model numbers were provided in the product data.
Installation should be performed by a qualified security technician or licensed electrician familiar with door hardware and low-voltage sensing systems. Disconnect power to any connected alarm or access-control system before mounting or wiring the bracket assembly. Follow the door manufacturer and sensor manufacturer guidelines for mounting clearances and fastener requirements. Local building and electrical codes may apply depending on the facility type and jurisdiction.
