Glass infill panel railing system is designed to work with Speed-Rail and Interna-Rail aluminum handrail systems. Made of 3/8 in. thick tempered glass, panels attach to handrail using 2-piece panel mounting clips that are made of corrosion-resistant, anodized aluminum and hold glass panels firmly in place from top and bottom to eliminate downward sagging or slippage. Panel promotes flexible design options for builders and architects.
