Automatic door bottom, mortised, 14 x 34 mm aluminium, 15 mm drop, bulb seal, for pivot doors

Automatic door bottom, mortised. The U-section body sits inside a groove routed along the bottom edge of the leaf, out of sight. 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.

Made for pivot doors: leaf-spring mechanism with a long actuating screw. 6063-T5 aluminium housing. Body section 14 x 34 mm, 15 mm drop. Rubber bulb seal. The mill does not name the seal compound. Supplied with two end plates of 22 x 60 mm and a 25 x 25 mm strike plate.
