Galvanized steel Projection frames
Lateral Lever galvanized iron projection frames are recommended for windows up to 1400 mm in width.
Beyond this measurement, up to a maximum of 3000 mm, we recommend the central lever model which includes a rod and a handle installed on the window sill. A double handle will be installed on projection frames from 2300 to 3000 mm in width, unless otherwise indicated.
Projection frames LL have arms with traditional arms with spring-loaded closure (arms length: 570 or 470 mm).
Galvanized iron projection frames LC are produced without welding between arms and rod: they are connected by a nylon axle box to avoid damaging the galvanization of various components.
On request, they are made with the traditional arms welded to the rod.
