Abstract: An improved gripping arm assembly including a two-piece gripper arm body construction which includes an arm clamp having alignment pins, and an arm main body with corresponding alignment holes for receiving the clamp pins, and a means for securably attaching the main body with the clamp. This two-piece gripper arm construction is simpler to remove than one-piece standard gripper arms. To replace a broken gripper arm with a new gripper arm only requires unscrewing fasteners holding the two-piece old gripper arm together allowing detachment of the broken gripper arm from the shaft, and clamping the two pieces of the new gripper arm together around the shafts and securing the screws and re-clipping an operating rod. The two-piece construction eliminates the need to remove a shaft from the machine or other gripper arms from the shaft when repairing or replacing one gripper arm or replacing or repairing a shaft having gripper arms mounted thereto.

Abstract: A routing clip for fixing a conduit to a support is integrally molded from a plastic material and includes a U-shaped channel having two substantially parallel walls extending therefrom.

Abstract: A hanger for attaching a length of a transmission line, such as, a coaxial cable or a waveguide to a supporting structure, such as, a crossbar on an antenna tower, includes two gripping elements. The elements have posts and openings to facilitate aligning of them with respect to each other. The posts and openings are arranged so that the posts in one element fit into the openings of the other element to help align the two elements when they are placed around a transmission line. Once aligned, the two elements are brought toward each other until they snap together to form a clamping structure which loosely grips the transmission line. The clamping structure can then be slid to the desired location on the transmission line. A bolt or a screw is then inserted through the aligned bolt or screw openings in the two elements and through the supporting structure.
