WingIt Grab Bar Fastening Systems are made from 18/8 Stainless Steel and can be used in most hollow wall construction (see Installation Instructions). Typical straight Grab Bars use 2 GBW50s. WingIts become waterproof as they are installed into the wall. GBW50s can be installed into wall substrates (tile, drywall, etc.) from 1.5" to 2.5" thick. GBW50s use 3M's best waterproofing adhesive to install completely waterproof in minutes. 1.25" hole required for installation
Wingit Fastening System is not compatible with HEWI Nylon Grab Bars.
