Concrete Ballast Brick 3kgs

This is a solid, dense 7.3N concrete brick measuring 215 x 102.5 x 73mm and weighing approximately 3.0-3.32kg, used as a smaller ballast unit in non-penetrating flat roof solar mounting systems. Made from secondary and recycled concrete materials with a natural grey finish, its brick-sized format suits fine-tuning the total ballast weight in a mounting frame or tray in smaller increments than a larger ballast block would allow. It stacks and packs alongside other ballast units to resist wind uplift without fixing through the roof membrane. This brick is a standard builders'-merchant dense concrete unit rather than a solar-specific product, and is supplied for this purpose by Travis Perkins.
