Grab bar mounting brackets made specifically for fiberglass installation have discs that safely distribute the weight of a person and prevent the fiberglass from cracking. By attaching the brackets to wall studs with bolts, you ensure that the grab bar will not pull out from the tub or shower wall when in use.
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.
