Unlike 3 hole flanges that limit screw placement, HealthCraft"s innovative 9-hole Easy Mount flange design allows for greater mounting flexibility to structural studs. * Also compatible with specialized grab bar fasteners and anchors that mount directly behind drywall, tile and other surfaces should stud spacing not permit direct mounting. See website for details. * All HealthCraft grab bars meet or exceed the guidelines of the Americans with Disabilities Act (ADA). * Stainless steel construction ensures that these grab bars will never rust. A simple wipe with a damp cloth is all that is required to maintain a clean attractive finish. * Flange covers conceal the screws creating a more seamless and attractive look.
