Mounted this grab bar for the three stairs in my garage. Mounted onto a hollow concrete block wall with 4 3/8" bolts. Had to order the bolts separately and could not find them locally. Used Toggler bolts.
My father used the bar and it was much easier for him to get up and down the stairs.
I would have given this item 5 stars if they would include screws or bolts and washers or even recommend an installation method. There is nothing included nor was I able to find anything on line. Other than that, it is a quality product.
