Trend AQ21/B/10 Aqua 21 style brown 10M Aqua 21 stripStrip is fitted into the door frame rebate (head and jambs) as three cut pces forming a compression or wiping seal. The seal is butt joined at the corners. To seal the door bottom, a weather bar is mounted into the threshold section. It is important that the seal does not abut the weather bar but runs to the threshold section in front (weatherside) of it, to maximise water permeability resistance.Specification-Colour=Brownlng.=10mSeal size excl barb=11.5mmx9.8mm
