A manually operated screw jack window opener is an elegant alternative to automatic window actuators. Using a traditional brass single thread screw jack lets you open and close hard to reach windows to allow natural ventilation of your rooms. The thread and handle hang down from your window or skylight so that adjustment is easy.
At Rocburn we have single thread screw jacks of various sizes available including brass versions with a thread of 300mm and maximum distance of travel of 255mm. The screw jack also acts as a locking mechanism on your window and holds it firmly in place when open and closed so there's no need for further locks and bolts.
Contact us for more details on the SST710-250 Single Thread Screw Jack 300mm in Brass.
