A traditional window opener or screw jack is threaded brass rod that when twisted using an opener pole or handle extends to open your window or roof vent. Screw jacks are particularly popular in conservatories, orangeries and skylight windows on a pitched roof but are also used in other situations such as flat roof vents and low level windows on a vertical wall.
