Window Stays / Restrictors

Window restrictors provide safe ventilation and deter unlawful entry.

Window restrictors are the perfect complement to insect screens allowing you to enjoy the summer breezes & bring in the fresh air - without bugs!

The Safetystay is a non-releasable restrictor for awning and casement windows, for those with safety and security in mind.

Viking Security can also engineer window restrictors for homes and commercial premises using Stainless Steel bar or Aluminium Extrusion.
See the photos below with restrictors designed to prevent objects being removed through windows and others to prevent windows opening into pedestrian walkways where the usual safety stays could not be used.
