The NOR510 Astragal Seal offers an elegant acoustic solution specifically for single action double doorsets fitted with a requisite door selector. The seal utilises the Norsound unique ‘dual air pocket technology’ which is proven to give greater noise attenuation.
Screen colour may differ from actual product colour. All technical information is given as guidance only. Due to the technical nature of our products they are designed to be installed by a professional.
You require a door selector simply because the product actually strides both door leaves so creates a primary and secondary leaf. If no door selector is present the secondary door may not close fully.
