The last remnant of the West Roman Empire was conquered in 486 when Clovis defeated Syagrius who had ruled over northern Gaul. That part of the Frankish kingdom would be called Neustria (the New Land) as opposed to Austrasia (the Eastern Land), which was the original core territory of the Franks.
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.
Grab bars can be purchased in sets of two, which allow you to install a vertical grab bar in a one-piece tub and shower for standing assistance and a horizontal grab bar to help people rise up or sit down in the bath tub.
