OBV Aluminium Adaptor for OBV restrictors.
An adaptor specially designed to be fitted with the OBV restrictors to allow them to be fitted to aluminium windows.
In the past it has not been possible to fit the extremely popular and widely specified OBV safety catch/restrictor to aluminium windows. To solve this problem, and to satisfy demand from the market, Winkhaus have purpose designed and developed an adaptor to enable the fitting of the product.
Manufactured with adaptability to suit the variable designs of aluminium Casement and Tilt-Turn windows the adaptor creates a solid and secure grounding for the OBV Safety Catch.
A choice of fixing holes provides the most suitable screw positions depending on profile design. Available in white powder coat finish (RAL 9016) or mill finish for self-coating.
Images are for illustration only, the main OBV restrictor part is sold separately.
