The present invention relates to a device and a method associated with the device. With respect to the device, it is a work holding and clamping device, which increases the usable span to almost twice its stored length. This device has an inner and outer assembly. The inner and outer assemblies are nested or telescopic. Each assembly is made of a square or rectangular tube that has a jaw affixed to one end. The inner assembly contains a locking mechanism to allow for length adjustment. When arranged so that the jaws are on the same side of the respective assemblies, the clamp is capable of a span that is almost equal to the length of the inner assembly. When arranged so that the jaws are on opposite sides of the respective assemblies, the clamp is capable of a span that is almost equal to the sum of the length of the inner assembly and outer assembly.
