They are extremely easy to operate and fold to approximately 15% of its secured position. Each sash can turn through 180 degrees to maintain access. Different lock options are available depending on the application.

trackless barrier

Trackless barrier system:

These barriers are an ideal system for access control or restricting access in shopping centres, factory units, car parks, loading bays, or simply partitioning and isolating areas off. The system is completely trackless and operate on a series of steel reinforced trolleys that allow complete mobility. They can be temporarily fixed in place with shoot bolts locking each trolley into the floor. If required, locking devices on the end posts allow them to be secured to walls. Spanning any width and heights of 2 and 2.5 metres.

emergency exit doors

For Emergency Exit doors:

We can also supply expandable barriers that have been specifically designed for securing emergency exits and vulnerable glass doors. The design enables occupants to unlock the gate from inside the premises by rotating a thumb-turn lock. This keyless operation ensures that a quick and safe exit can be achieved at all times. As with our other expandable barriers there are no tracks and the grille hinges aside as standard.

 

 

lock shield

The attack side of the gate retains a key operated lock to restrict access.

The tight double diamond pattern combined with a shielding plate, prevents intruders from reaching through the lattices to unlock the gate.
