DUO in action

Maximised durability and manoeuvrability

DUO’s lightweight design makes it easy to handle on-site with good finish.
Ease of use

PERI has designed DUO to be simple to use and intuitive as possible. When forming the slab, work is completely carried out from a safe position below; the panels are simply hooked in and then pivoted upwards.
