Description

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

The Harmer Roof Detail Gulley outlet is for use in roof constructions incorporating formed drainage channels. It is specially designed to suit restricted width gulleys which are too narrow for standard outlets. It directly connects to cast iron pipework via suitable coupling or to PVC O-ring socketed pipe.
