ACO HP two-way screw outlet
Description

The two-way outlet is designed to be used at the junction of roofs and parapet walls, or wherever a horizontal and vertical surface meet. Available to fit pipe sizes of 50, 75 and 100 mm. This flexible design of outlet allows either horizontal or vertical outflow take-off.

Screwed rainwater outlets are recommended where connection to the outlet occurs within the thickness of the slab, and threaded connections will form a completely gas-tight seal. Two-way screw outlets have a female parallel thread to BS 21 for connecting directly to threaded tubes conforming to BS 1387. This ensures a completely watertight seal when screwed fully home into the outlet body.

A range of PVC adaptors are available to allow connection to aluminium pipework, socketed and socketless cast iron pipework and PVC pipework.
