Spiral Duct Access Door.

The spiral or circular access doors manufactured by AJS are as standard produced in galvanised steel, however can be finished in both 304 and 316 stainless steel. An additional chain can be added for extra safety whilst removing the door and trying to gain access to the duct system - the chain is fitted to the outer door panel and into the main duct itself. Additional rubber edging can be cut to size and provided to cover rough edges on the duct to lower the risk of injury. Conical springs have been added between the outer and inner panels, to help in installation and inspection of the ductwork.
