Hinge composed of two rectangular plates articulated by a knuckle and secured by an iron pivot pin. The elements are formed from a single sheet, extended at the ends to create the lateral loops of the knuckle in one plate and the central loop in the other. The pin, made from a cylindrical rod, has its ends hammered and expanded to secure the circular elements forming the hinge. The plates were fixed using quadrangular-section nails, one of which remains in place. Each plate has two square perforations aligned along the centre. The nail is complete, although bent at the lower end, and has a quadrangular section with a trapezoidal head.
