Bath shower-screen bottom seal x 2 (Central Crouch End N8)

800mm long, to fit 6mm thickness screen (though it might work for a 4mm one).
It has a double flange, the lower one tightly against the bath edge to prevent any leakage, the other overhanging it to redirect most of the drips. See the second picture of the cross-section: the screen slides in along the gap at the top; the overhang flange is to the right below that and the bath-edge flange is visible at the bottom.

I have 2 of them, so if more than 1 person is interested I'll give one to each.
