Manthorpe Lintel Trays can be fitted above a door or window opening to remove rain water that has been rain-driven through the brickwork. The Lintel Tray is made from tough, durable polypropylene and will protect cavity wall lintels against corrosion from moisture. When teamed with Manthorpes Weep Vents and Stop-Ends, the flow of water is prevented from spilling over the ends of the lintel into the cavity below and redirected out through Peep or Weep Vents. The range of Lintel Trays is fabricated in three different sizes to fit cavity widths up to 150mm and lintel heights of 230mm. Each size is available in rolled lengths of 5 and 25 metres. The GW324 and GW325 cavity cloaks are designed for use around arched and round window openings to give 180 and 360 protection.Manthorpe lintel traysGW281:Width: 400mmLength: 5m roll and 25m rollGW282:Width: 463mmLength: 5m roll and 25m rollGW283:Width: 530mmLength: 5m roll and 25m roll
