Enstall FlatFix Fusion Ballast Holder 2100mm

The Enstall FlatFix Fusion ballast holder is a 2100mm-long container designed for flat roof PV system installations. It is installed beneath solar panels, between long mounting elements, and holds concrete paving stones or gravel to secure the PV array without roof penetration.

The ballast holder is constructed from Magnelis ZM310-coated steel (material 1.0242 S250GD, 0.75mm thickness) for corrosion resistance. Always install two roof supports under each long mounting element when using ballast containers. Recommended ballast consists of concrete paving stones no larger than 21 × 21cm; if using gravel, place paving stones on the left and right edges to prevent spillage.

Part of the FlatFix Fusion system, a lightweight flat roof mounting solution backed by a 20-year manufacturer warranty and designed for quick installation on nearly all flat roof types.
