Joints
An oblique, housed (dadoed) and rabbeted scarf joint. The upper and lower pieces are exactly the same but reversed. The upper part is fitted into the lower part from the side and two pins *sen 栓 are driven through the two mortises. The result is a very tight and stable joint used to join ground sills and various beams that must withstand great stress and strain. Okkaketsugi 追掛継 is identical to okkake daisentsugi except that pins are not inserted.
