A hook gate or hoist hook having a hook gate that is designed to prevent dynamic rollout. The lockable gate includes one or more release mechanisms that allow the gate to unlock and open upon actuation of the release mechanisms. The release mechanisms reside within a circumferential guard that extends outwardly from the gate. The guards preferably extend at least as far as the release mechanism or beyond the extension of the release mechanism. The hook gate further includes anti-snagging flanges extending generally in the vertical direction from both the top and bottom portions of the guard. The circumferential guard and the anti-snagging flanges in combination make it nearly impossible for an attachment mechanism to become improperly oriented under a load and effectively eliminate the possibility of dynamic rollout.
