a movable anti-shear mechanism coupled to the base, the anti-shear mechanism including a carrier, a first shear pin and a second shear pin coupled to the carrier for movement with the carrier relative to the base; and
a keeper extending through the face wall and coupled to the carrier, the keeper arranged to extend along a first axis,
wherein the keeper and anti-shear mechanism are movable together relative to the base between a retracted position and an extended position, the keeper extends outward from face wall and the first shear pin and second shear pin are substantially received into the base relative to the face wall with the anti-shear mechanism in the retracted position, the first shear pin and second shear pin extend outward from the face wall with the anti-shear mechanism in the extended position, the first shear pin is arranged to extend along a second axis substantially parallel to and spaced apart from the first axis, and the second shear pin is arranged to extend along a third axis substantially parallel to and spaced apart from the first axis opposite the second axis.
