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.Manthorpe lintel traysGW281:Width: 400mmLength: 5m roll and 25m rollGW282:Width: 463mmLength: 5m roll and 25m rollGW283:Width: 530mmLength: 5m roll and 25m roll
