The G952 has been designed to provide retrospective ventilation to cavity walls where no or an insufficient amount of Weep Vents have been used. In addition the G952 can be used to ventilate rendered wall where standard weep vents are notoriously difficult to detail. The product is quick and easy to install and comes in a range of colours to suit all common brick and render finishes.

The protruding drip feature on the front face of product directs moisture away from wall rather than down onto it which could lead to unsightly stains and damp patches.
