Aquamac 21 is inserted into a groove cut into the rebate of the door frame. The groove can be cut using this specially made Axcaliber spindle moulder disc. The disc has 2 tungsten carbide teeth and is available with either 30mm or 1.1/4" bore. The disc is 150mm in diameter. Aquamac 21 is a very simple but effective wiping seal which reduces draughts to a minimum. Inserted into the side of the rebate the seal is quick and easy to fit, taking up any discrepancies between the door and the frame. Available in white or bronze in 10 metre or 25 metre packs.
