Automatic door bottom, mortised, flanged, 25 x 44 mm aluminium, 15 mm drop, fin seal, wide flange

Automatic door bottom, mortised, flanged. The body sits in a groove routed along the bottom edge of the leaf, and two aluminium flanges cover the groove edges. As the door closes, the plunger at the end of the bar meets the frame and drops the seal onto the floor; as it opens, the seal lifts clear and does not drag. The mill states it keeps out dust, odour, insects, draughts, noise and light at the door bottom.
