Introducing the completely new, fully featured stay from DGS.
For fire escape, easy clean and child safety.

Does your current fire-escape stay offer:

• Full egress to BS 5588?
• Child safety restriction to BS 6375?
• Super smooth EasyClean operation?
• Basic Egress Stays without a restrictor function risk the possibility of children opening a window and falling out or even climbing up to an already open window.

It has always been our recommendation to use DGS Restrictor Stays as a safety precaution.

The main difficulty with Egress Stays is cleaning of the window from an internal position. Up to the present, we have only been able to offer Egress Stays with either EasyClean or restrictor functions, never both.

The new DGS Tristay overcomes this problem combining, as it does, all of the three required elements.
