Solid Support

• Grab Bar ends must be mounted with both end positions over a wall stud. A stud finder can be used to locate wall studs. Contractor is responsible for installing Grab Bar to wall studs as instructed.
• Secure through wall board or tile to the wall stud so as to hold a minimum of 250 pounds of force.
• At least two (2) of the three (3) wood screws provided must be used on each end of the Grab Bar, top and bottom, to properly secure. Standard size wall stud limits using more than two (2) wood screws.
• If using a drill to install wood screws, a drill bit extension must be used to avoid damaging the Grab Bar.

Installation (Wall & Wall Studs)

1) Place Grab Bar at desired position. Slide covers over bar to reveal flanges. Mark drill hole locations with pencil at each end on inner side of flanges.

2) Remove Grab Bar from wall. Use drill with 7/64" drill bit to drill holes into wall and wall studs at the marked positions.

3) Align mounting holes on Grab Bar with drill holes. Insert wood screws into pilot holes for wall and wall studs. Hand tighten wood screws.

Installation (Wall & Wall Studs) Cont.

4) Tighten all wood screws using a phillips head screwdriver, securing Grab Bar to wall.
