The Pyro-Chem Tyco surface mount fire extinguisher cabinets have a durable polyester powder-coated finish over a tough galvanized steel welded box. Stronger than aluminum cabinets and less expensive than aluminum or stainless steel cabinets, these cabinets provide exceptional life and reasonably priced fire extinguisher protection. The injection-molded clear "break-glass" pane has no sharp or rough edges like other custom cut panes; making replacement or extinguisher servicing easier and safer for the fire extinguisher technician. Improved pane retaining hardware provides easier installation and removal of the pane for servicing the extinguisher. The cylinder tumbler locks are keyed-alike giving technicians easy access to the extinguisher inside the cabinet without carrying and trying multiple keys.
