MEGADUCT 220 FLAT CHANNEL CONNECTOR WITH DAMPER
Please note that the Domus / Megaduct DOM927 is designed for use with Domus ducting – most other 220×90 plastic ducting systems are compatible but may require some manual adjustment on-site to ensure that the damper valve opens and closes.
Please note that this product is not designed to be airtight.
Horizontal use only.

Ok, but flap tends to jam when ducting not quite square
