Gunnebo Johnson Corporation midget models OB-3JEM-28-4 and OB-3JEM-28-7 have an advantage in size, as well as capability. They are unusually short in overall length, the basic eye-top unit being only 13-7/16 inches. Other units in this low profile series include jaw types and the versatile wedge socket types.
