Refurbishment Cavity Tray 450mm

Refurbishment Cavity Tray 450mm is designed to provide protection where a new horizontal roof abutment meets an existing wall. It can also be used where the original system has been found to have degraded or even left out of the wall construction. The tray has a unique front mortar clip that can be removed at any time once the mortar has set leaving a 25mm deep aperture into which the lead is inserted and secured with lead wedges.
