WHAT IS BENDING RAIL? Bending Rail is designed for making curved railings on most curved staircases and balconies at the jobsite. Bending handrail comes in multiple layers (ply) and is glued together to form the new handrail. Each ply comprising the bending rail is designed and manufactured with a tongue-and-groove bead to create an alignment of the plys. When assembled, bending rail results in a match of a standard rail profile. Photo © affordablestairparts.com.
