1. A link for a chain, comprising:
a base;
a first wing connected on a first side of the base perpendicular to the base, wherein the first wing defines a first through-hole;
a second wing connected on a second side of the base perpendicular to the base and opposite to the first side, wherein the second wing defines a second through-hole aligned with the first through-hole; and
a header connected on a third side of the base perpendicular to the base, the first wing, and the second wing, wherein the header defines a third through-hole in a parallel plane to the first through-hole and the second through-hole and defines a fourth through-hole in a perpendicular plane to the third through-hole, and
wherein the fourth through-hole is located at a height above the third through-hole relative to the base along a first direction defined by the link, and wherein the fourth through-hole is spaced from the third through-hole along the first direction so that the third through-hole and the fourth through-hole do not overlap along the first direction, and
wherein the header has a wall that extends in a plane perpendicular to the first and second wings and to the base, and wherein the header has an extension extending from the wall in a direction opposite in which the first and second wings extend from the wall, and wherein the third through-hole and the fourth through-hole are both defined by the extension.
