The RB1 ballast blocks are designed to sit over the narrow rails of some roof-mounted solar racking systems.

RB1 ballast blocks are available in many sizes. The larger ones have threaded inserts cast into the top surface for machine-assisted lifting.

To help protect delicate roof surfaces, RB1 blocks can have optional neoprene strips adhered to the bottom of the block.
