Purpose-designed for the base of vertical soil stacks, this long-radius 87.5° rest bend provides a stable, controlled transition to the horizontal drain while supporting smooth hydraulics and easier maintenance. The integrated rest foot offers a secure bearing in the excavation, improving positional stability and aiding correct alignment. Its ring-seal push-fit sockets enable rapid, watertight jointing with plain pipes or spigots, avoiding hot works and solvent use. Recent product updates include a larger, deeper rest foot for stability, an EPDM Blue Ring Lock Seal that resists distortion thanks to a rigid support ring, and a single-piece moulded body for long-term integrity. It meets UK requirements for use at the foot of the stack and carries the BSI Kitemark to BS EN 1401-1.
