The Defender Restricted friction stay combines two safety features in one mechanism. The built in child resistant mechanism limits the initial opening of the window to 100mm. A quick release function allows with window to be opened fully for easy cleaning and maximum ventilation. The restrictor automatically relocates and resets when the window is closed.

As with other friction stays in the Defender range, the restricted variant offers enhanced weather sealing from the extended enclosed end cap.
