A clevis and drawpin apparatus has a top strap defining a top pin hole, and a bottom strap defining a bottom pin hole having a diameter less than a diameter of the top pin hole. The top and bottom straps are fixed together such that a gap is formed between them and hole centers are aligned. A drawpin has a head that rests on the top strap, and a top pin portion with a diameter equal to the diameter of the top pin hole, a bottom pin portion with a diameter equal to the diameter of the bottom pin hole, and a middle pin portion extending through the gap. The middle pin portion has a diameter equal to the diameter of one of the top and bottom pin holes. A handle on the drawpin and a lock member are configured to prevent upward movement of the drawpin. |
