The Series 9300 lift rolling steel doors have a revolutionary new design that reduces installation time without compromising security. They're equipped with the exclusive Smart-Lock System, which allows end users to engage the lock at a convenient height and then close the rolling steel door to the floor.
Two standard mounting options are available: E-Mount or Z-Mount.
Aluminum mounting angles may utilize a hollow, double-wall design to completely hide guide fasteners.
Tubes are mounted into a sleeve cup on the slab and attached to the steel joists at the top. This allows for the grille/closure to be installed first before any walls are built eliminating the difficulty of working around studs, HVAC and plumbing.
