How big of a hole do I need to install the Grab Bar WingIt?
1.25″ – don’t worry its all part of the engineering. If you are installing into Ceramic Wall Tile or any difficult material, use our Carbide Hole Saw (CTHS114) – one of the best bargains out there. The 1.25″ hole is part of the structural integrity of the WingIt. Remember that the WingIt incorporates the best waterproofing material from 3M and even seals over grout lines.
