Securistyle has unveiled the NYCDoH-accredited Sterling Advanced Detachable Restrictor.

Its 15.5mm and 13mm brackets have been specifically designed for both standard and slim channels in aluminium profiles. When installed with Securistyle’s Sterling or Storm Balanced heavy-duty hinges, it can be used on either top-hung or side-hung vents.

The restrictor has been approved by the New York City Department of Health (NYCDoH) for compliance with its falls programme.

Suitable for 16mm-18mm hardware cavities, the solution features a crack stop design for a positive stop and a unique locking pin design that enables simple detachment and engagement of the restrictor stay via a key for authorized release only.

The product comes with a 12-year mechanical guarantee and a 12-year surface finish guarantee. It is also tested to EN 13126-5 for height windows, achieving Grade 1 in impact testing.
