One-piece Parting Bead that weatherstrips both top and bottom sashes.

Normally used exclusively in Refurbishment where larger toerances are encountered, (measuring 16mm from wingtip to wingtip)

Looks exactly like traditional Parting Bead - the fins are almost undetectable when installed.

Will never rot - made from UV-Stabilised PVC.

Unaffected by accidental contact with paint.
