Designed to fit casement windows and to match the products in our Monkeytail range. These fasteners are handed, so it's important to make sure you choose the correct hand. From the inside looking out, if your window is hinged on the right hand side then a right hand fastener is required and vice versa. Suitable for use with weather-stripped windows. This handle is night-venting and can be locked in a closed position as well as two open positions to allow some ventilation. Overall Length: 157mm Handle Length: 140mm Fixing Plate Size: 64mm x 16mm x 5mm Keep Projection: 27mm
