Jointing Blocks

Jointing blocks - also known as modesty blocks, assembly blocks, or KD blocks - are the plastic corner connectors used to join panels at right angles in self-assembly and flat-pack furniture. At the DIY Hardware Store, our jointing blocks cover the most commonly used types for kitchen unit carcasses, shelving units, wardrobe frames, and DIY panel furniture projects.

A jointing block screws to both panels at the internal corner of a joint, holding them square and rigid without the need for glue, dowels, or more complex cam lock hardware. The two-part rigid joint with cover plate gives a clean finished appearance on exposed internal corners, while the simpler modesty block format suits hidden joints inside carcasses. KD (knockdown) assembly blocks allow the joint to be dismantled and reassembled, making them ideal for furniture that may need to be moved.

Quick to fit with a screwdriver and very forgiving of minor panel misalignment during assembly, jointing blocks are the accessible solution for anyone building their own furniture or repairing existing flat-pack units at the DIY Hardware Store.
