GEAQUELLO® R 312 / R 380

The GEAQUELLO^® R 312 / R 380 formwork modules are used to construct end walls within cable sleeve firestops. One end wall is required for vertical sleeves; two end walls are required for horizontal sleeves. The modules serve as permanent formwork and as spacers between individual cables and the sleeve wall. After installation, they are treated with the impregnation fluid GEAQUELLO^® E 824, causing them to expand and become fire-retardant.
