The Access SST is a 100% stainless steel door – frame and panel – available in 304 or 316 stainless.

Stainless construction – including hinges and screws – allow this door to last longer in harsh environments. Our proprietary EPDM gasket is lab tested and customer approved for a lifetime of high performance sealing. Mitered frame corners are welded and passivized, providing a great looking door.  As with our other access doors, the Access SST is available with window options framed in stainless steel.
