110mm Underground 90° Access Bend Double Socket

The Kalsi Group Double Socket Access Bend 110mm 92.5° Underground Fitting is a mid-brown uPVC push-fit drainage bend designed to redirect 110mm underground soil and waste pipework through a near-right-angle with a slight self-cleansing fall. Manufactured by Kalsi Plastics at their Birmingham plant, it is built for gravity drainage and sewerage applications in both domestic and commercial new-build and retrofit projects. The integrated access cap allows inspection and rodding without disturbing the surrounding pipework — a key requirement under current building regulations.
