The threshold section is in two separate parts to facilitate fixing.
The rear section, BDB, extends from the frame & is fitted tightly against the back of the stops. It acts as a barrier across the threshold, making a conventional water bar unnecessary.
Any small amount of water which gets past the seal is caught by the trough.
The holder BDWB (BD Weather Board) is screwed to the front of the door through oversize holes which permit fine sealing adjustment. It contains two blades, a storm seal, BDD, at the front which seals on the BDA, & the main seal, BDC, which seals on the inside of the trough BDB when the door is closed. BDWB also forms a rain water deflector.
