Spanning an impressive 1206mm, this block is built with high-grade 18mm block board panels to resist bowing under heavy weight. The interior is divided by robust middle panels equipped with dedicated door holes, allowing you to split the massive shell into multiple distinct cabinet zones. The perimeter panels feature our signature hole placement array—drilled a quarter-way from adjacent ends and halfway from one another—ensuring perfect alignment when building asymmetrical or stair-stepped partition layouts. A continuous 10mm groove pattern runs along the side, top, and bottom panels, leaving a precise (18+18) mm un-grooved clearance area at the back to safeguard the inset French cleat system.
