The GA1-10 universal cavity tray is a polypropylene bridging piece for managing water at roof abutments. Its design helps divert moisture from junctions where pitched roofs meet cavity walls in brick, block, or timber-framed construction, reducing the risk of damp ingress.
Supplied flat with pre-creased folds, it can be shaped on site to suit catchment, left and right hand, or ridge tray applications. The adaptable tray covers cavity widths from 50mm to 100mm, making it suitable for a range of standard wall constructions and roof pitches up to 60 degrees.
