The Manthorpe Diamond Weep Vent Black is a high-quality drainage vent designed to promote self-cleaning and removal of debris build-up. Its unique diamond shape profile helps to increase the drainage flow rate along the base of the channel.

Product Features:

• Diamond Shape Profile: Increases drainage flow rate and promotes self-cleaning.
• Ribbed Outer Walls: Create a robust mortar key for a secure fit within the outer leaf construction.
• Flush Face: Finishes flush with the brickwork for quick detailing into the mortar joint.
• Tapering Outlet: Designed for easy cleaning.
• 65mm Rear Opening: Ensures optimum drainage inlet from within the cavity, as per NHBC Technical Extra 17 guidance.
• 4mm Minimum Opening: Ample for water drainage but small enough to prevent entry of large insects.

Available in clear and a range of colours to match various wall and mortar finishes.
