Designed to fit casement windows and match the monkeytail window stays in the range. The product is handed and therefore care needs to be taken when choosing the correct hand. From the inside view, if your window is hinged on the left then a left-hand fastener is required. Suitable for use with weather-stripped windows. The handle is night venting and can be locked in the open position as well as the closed position allowing some ventilation.
