Product details:

Durable die-cast zinc posts and a stainless steel bar for a rust-resistant, top quality strength that's built to last. Straight forward installation into studs with included instruction sheets and wood screws. Assistance for up to 500 pounds, double the ADA grab bar requirements. Brushed nickel finish to complement matte nickel faucets and bathroom hardware. The 36-in grab bar is perfect for the long wall of the tub or anywhere you need leverage and support, and will meet ADA commercial bathroom requirements when installed behind the commode. 1-1/4-in bar diameter which is better for gripping. Cover snaps over grab bar mounting flange to hide screws. Installs easily with a grab bar wall anchor (included) if no studs are available.
