Securistyle Defender Standard

A high performing friction stay, the Defender Standard achieves enhanced weather sealing by means of an extended enclosed end cap and asymmetric location system for reliable weather sealing to BS 6375-1. The handed 'profiled' vent arm further enhances weather sealing.

Smooth operation is ensured by a patented lipped slider, as well as easy friction adjustment without metal to metal contact.

The Defender has a long and reliable working life tested to 30,000 cycles. A unique patented, robust cam friction device eliminates any risk of friction screw misuse.
