Holes are pre-drilled for High Light boards but will also mount standard Quantum Boards with extra drilling.
Will not accommodate driver mounts.
Designed for remote drivers.
Heatsinks include 5mm mounting holes at each corner and in the middle of the heatsink (6x total) for ratchet hangars or aluminium tie bar connectors etc, plus an 8mm cable hole in the middle.
These are basically a heavier version of a Slate 2 triple heatsink.
