The flat, elongated design will not rotate, ensuring perfect alignment for both edge and face gluing. Suitable for both plywood and solid wood applications, the dense Sipo tenon will not expand or telegraph through material, leaving you with clean, flat, and consistent surfaces. The Sipo Tenon is embossed with glue pockets, and is approximately 2mm shorter than nominal length, allowing space in the mortise for glue. Sipo Mahogany For Outdoor Use, 5 x 19 x 30mm, 900-Pack.
