Abstract
The frictional grip tool holder includes an extruded plastic housing (A). The extruded housing defines an integral, first mounting channel (12) and a facing second mounting channel (14) which define a planar region therebetween. The housing further defines an integral stabilizing channel (20) which is disposed directly above the midpoint of the planar region. A first resilient finger array (B) is mounted in the first mounting channel extending along the planar region; and a second finger array (C) is mounted in the second mounting channel extending along the planar region. The first and second finger arrays terminate in free finger ends (40, 42) contiguous with each other below the stabilizing channel. A bolt-like threaded member (50) extends through the housing adjacent the first and second mounting channels. A threaded knob (52) is received on a threaded end of the bolt-like member for selectively urging the first and second mounting channels toward each other against the resilient biasing of the plastic material of the housing and for selectively permitting the resilient plastic material of the housing to urge the first and second channels further apart.
