Hi Pinenot,
Yes, i though this was some sort of vent but I think you're right. It's a multi slotted panel for the handle to engage with. I've taken the two screws out on the handle bracket and the handle doesn't turn anything - it's just a push/pull by the looks of it. I don't want to push...
I've just moved into a house with a skylight in the upstairs landing. However, the handle from the skylight seems to be missing. Excuse my ignorance, but how do I open it. Do i just push (or pull)! How do I tell if it does open. many thanks. Pete...
