When the temperature falls a heavy spring pulls the window closed. No electricity is needed!
A manual opener that works like a large threaded screw - for Royal or Junior Victorians (please note if the long handle is needed)
Mounted underneath roof window. Includes a slot/brush "seal" opening for the window opening device'
20 Stainless Steel hammerhead bolts and nuts - can be inserted in the channels in any of the aluminum frame profiles - turned 90º - these to attach accessories such as shelving later.
