  • Patent number: 4195827
    Abstract: Set out herein is an improved conduit cutting guide including a longitudinally hinged handle formed in the manner of a trough and lined with segments of rubber or plastic for grasping the surfaces of a spirally wound flexible conduit therein. One end of the handle is attached to a first set of J-shaped end plates, each end plate being respectively fixed to one of the hinged portions of the handle, the first set of end plates extending above the handle trough to form two outwardly and downwardly directed end tabs. A second set of J-shaped end plates is attached to the respective first set, the second end plates being similarly conformed in plan form and include an offset for receiving the hacksaw blade therebetween. Thus, a conduit may be placed into the interior of the hinged handle and may be grasped thereat by the user. A hacksaw is then insertable into the space between the first and second sets of end plates for cutting the conduit.
