Abstract: A hand powered tool for installing a removable fastener of the type having an elongated shaft, a fixed support and a plunger. The plunger is biased relative to the fixed support for installation and removal of the removable fastener in a pre-drilled hole of a workpiece by applying force to the plunger relative to the fixed support. The elongated shaft is operably connected to the plunger whereby movement of the plunger relative to the fixed support varies the diameter of the elongated shaft such that the diameter of the removable fastener can be decreased to permit insertion of the elongated shaft into the hole of the workpiece, and increased to prevent removal of the elongated shaft from the hole formed in the workpiece. The tool is provided with a barrel assembly, a fastener assembly and a handle assembly. The barrel assembly has an elongated barrel, and an anvil supported by the elongated barrel such that the anvil is movable in a first direction and a second direction.

Abstract: A system and method for use in the installation of cable between support poles and other structures is provided including brackets, support rollers, clamps, pins, and pulleys that are used to support, guide, and pull such cables during the installation process. The installation tools also allow for the securement of the communication cables to messenger cables which support the communication cables during mid-span runs. The system also utilizes a series of modular pulleys that allow for installation of the cable along pole lines including inside and outside corners. A rope is simply threaded through the various components and the cable is then pulled in using a standard winch, without the necessity of a lift truck that requires a worker to work for extended periods of time at an elevated height. Such installation practices as performed by the present invention allow copper and fiber-based communication cables to be installed safely to reference to the cable integrity as well as to the worker.
