Made from solid hardwood stock, Domino Beech Tenons form the basis for strong joints that will last a lifetime and beyond. Rotation-proof, solid wood Domino tenons fit precisely in the mortise created by the Domino XL. All Dominos feature glue expansion slots that are designed into their surface to ensure a solid, long-lasting joint. Available in shorter, standard dimension lengths as well as longer 750mm (29-1/2″) long pieces that can be custom cut for any application.
