All our carcasses are constructed with 'Festool dominio' dowels. These are perfect for bespoke cabinets as we can place them without being constrained by manufacturing guidlines. This means we can produce any cabinet, any way.
We reinforce our domino assembled cabinets with pocket hole screws, these allow us to make a cabinet that is both very strong and easy to reassemble. They require a special driver bit, but we make sure every kit has one.
Where it is unseen or where a small fitting is required, we may supply screws and glue. but everything will have been prefitted first.
