Harmer Detail is a range covering all the awkward detailing situations that occur in new building design and refurbishment.

The Harmer Roof Detail Two Way outlet is for use where an angle is formed by the intersection of vertical and horizontal surfaces. It is installed to provide either vertical or horizontal take-off. It directly connects to cast iron and PVC pipework by means of a Harmer screw threaded adaptor and appropriate coupling.
