Sipo Tenon stock for outdoor use in sections made to be cut to length. Made from solid, rot-resistant Sipo mahogany stock, Domino Tenons form the basis for strong joints that will last a lifetime and beyond. Tenons should be cut 2 - 3 mm shorter than the mortise depth to create a glue pocket. Serves as a true floating ten Tenon in mortise and Tenon applications. Flat, elongated design will not rotate, ensuring perfect alignment for both edge and face gluing.
