Grab bar shall have 18-gauge (1.2mm) wall thickness and 1–1/4 in. (32mm) outside diameter. Flanges shall be 3/16 in. (5mm) thick stainless steel plate, 3" (75mm) diameter, and equipped with three screw holes for attachment to wall or floor. Swing-up grab bar shall be manually raised for approach or departure and lowered to horizontal position for support; counterweighted design shall prevent grab bar from falling back down to full horizontal position once grab bar is raised more than 45 degrees from horizontal position. Swing-up grab bar can support loads in excess of 250 pounds (113kg) if properly installed, complying with barrier-free accessibility guidelines (including ADAAG in the U.S.A.) for structural strength.
Caution: Grabs bars are no stronger than the anchors and walls to which they are attached and, therefore, must be firmly secured in order to sustain the loads for which they are intended. Swing-up grab bar is manually raised for approach or departure and lowered to horizontal position for support; once grab bar is raised more than 45 degrees from horizontal position, counterweighted design prevents grab bar from falling back down to full horizontal position.
