Industrial WB1A Wall Box Assembly

The Sloan WB-1-A Easy Access Wall Box is an industrial wall box assembly for concealed flushometer installations, designed to fit a 12" x 12" wall opening with a 13-1/2" x 13-1/2" #304 brushed stainless steel wall panel (16 gauge) and a steel frame. It includes four spanner screws with a spanner bit and grouting pins to anchor the frame to the wall and is compatible with Sloan Royal, Regal, Naval, and hydraulic concealed flushometers. The wall box and flushometer are ordered separately; when pairing with a Sloan flushometer (non-hydraulic), specify the WB variation (Model 152-WB) to ensure the correct push button/handle assembly, and for hydraulic models order HY-33-A Fixture Wall or HY-108-A MBPM actuators.
