Esinplast has created a system for manual fastening of the casement window through a fully retractable arm to be applied both laterally and under the casement window.
The opening of the retractable arm, being the reversible accessory, can be oriented to the right and left according to the type of the door/window which is used.
Once used it can remain between the casement window and frame.
Can be easily applied on the casement window
