Abstract: An overflash jig for pulling a cable along a support line via a tow rope such that when the tow rope is slack, the overlash jig does not retreat along the support line thereby slacking the cable. The jig includes a body having a pair of side plates and a pair of rollers rotatably mounted therebetween for engaging the support line. The overlash jig also includes fixed and movable brake shoes for frictionally engaging the support line and a coil spring for urging the movable brake shoe toward the support line. A plurality of pulleys interact with a rope attached to the tow rope to compress the coil spring when tension is applied to the rope. As the spring is depressed, the movable brake shoe moves away from the support line, and the overlash jig may be pulled along the support line. The tow rope may also be detached from the pulleys and attached to the body to apply tension to the cable while the overlash jig is maneuvered around an obstacle, such as a utility pole.

Abstract: An aerial block which is releasably mounted on a support cable either at a pole or in a span between two poles for installing coaxial aerial cable which then is secured to the support cable. The block has a frame formed by two spaced generally L-shaped members connected by a lower stabilizing bar. The vertical upstanding portion of each L-shaped member has a hooked end which suspends the block from the support cable at a pole location. The stabilizing bar abuts the pole to maintain the frame in a position wherein the leg members extend horizontally outwardly from the pole to provide two spaced points of support for a coaxial cable being installed to prevent kinking or bending of the cable. A spring-biased plunger mechanism is provided on each of the vertical leg members for releasably attaching the frame on the support cable between poles.
