These grab rails from Z-Tec are made from Steel and have a "knurled" chrome finish on them to give extra grip. They are available in three designs. Two straight rails measuring 12" or 18" (from centre of either fixing point) and an angled rail. The angled rail is two rails of 12" length separated at 45 degrees. Once fitted to the wall the gap between the back of the rail and the wall is approximately 66mm (2.5").
All these rails are supplied with screws and plugs however you may need to purchase different ones depending on the type of wall these are being fitted to.
