Quantity of white Crittall secondary glazing. The frame fits into the window reveal and then the sliding panels fit into the frame. The various parts are screwed together so could be made smaller to fit your window if you can wield a hacksaw, drill and screwdriver
Quantity of grey 3 inch guttering pieces
Two old oak timbers 7cm*11cm*201cm
I live near Bury St Edmunds
