Prevent falls, not freedom. The Duomode sashless window’s patented locking system allows its large, frameless panes to be used as either a counterbalance window or a servery window. So you get the largest possible view, along with unmatched flexibility.
You also get peace of mind, because you can restrict the Duomode’s bottom opening to 125 mm while the top pane remains fully operational. Live uninterrupted. aneetawindows.com
