ABSTRACT:
A test core clamp comprising a first longitudinally split tube comprising a split portion having opposing ends and attached to a base, and a tightening device for moving the opposing ends towards each other. The tightening device comprises two brackets one affixed to each of the opposing ends and both having apertures therein. One of the bracket apertures is threaded to engage one end of a clamping bolt inserted through and rotating freely within the other bracket aperture such that rotation of the clamping bolt causes the opposing ends to close or open. According to a preferred embodiment, an insert comprising a second longitudinally split tube having a plurality of fins extending radially from its outer surface is slideably located inside of the first split tube with the fins frictionally engaging the inner surface of the first split tube such that closing and opening of the first split tube results in opening and closing of the second split tube.
