Our double-flanged restrictor is ideal where paired window vents sit close together.  It allows both sides of each opening vent to be restricted, preventing weak spots or twisting forces that could compromise security and service-user safety.

Fabricated from 3mm steel for strength and surface treated to prevent corrosion, our restrictors are designed for ease of maintenance.  They also match the discreet style of our single-vent restrictors for consistency and improved aesthetics.

Available in a full range of RAL colours, our restrictors fit vents of differing sizes.  Bespoke options can also be made for other window configurations, allowing protection of almost every style.

Double-flanged restrictors are appropriate for common areas where observation is possible, to minimise the risk of service users creating a ligature point by passing a cord round the frame between windows.

Suitable where the gap between vents is between 15 and 50 mm.
