HammerBlow Corp. says its Bulldog 180 Series square jacks for tandem operations are designed to make tandem jack installation and operation more efficient and functional.

With Bulldog’s pin front design, the same jack fits in both the left and right position of a tandem setup. Ordering, inventory, and installation are made simple with only one part number where once there were two. Installers don’t need to reverse gears and can’t confuse one for the other because there’s only one model for both positions. The pin faces to the front instead of the side, giving more clearance and more options when choosing weld positions.

The company says the optional spring return drop leg makes Bulldog jacks the smoothest raising and lowering jacks in their class. Unlike ordinary drop legs, a Bulldog spring return drop leg allows quick and easy changes to the height of the leg. The spring bears most of the weight of the leg, allowing easy one-handed adjustments.
