(under subclass 135) Devices generally tubular in form, adapted to be placed around one or more conductors, and supported by the latter, to prevent an adjacent structure, such as a tree, from injuring the conductor or its insulation. The device is usually but not necessarily, formed at least in part of insulating material.
(1) Note. Compare this class, subclass 147, for mid-line spacers designed to prevent contact between two or more conductors which cross one another.
(2) Note. For similar structures designed to be placed about conductors for preventing accidental contact therewith by persons or animals, see this class, subclass 5.
(3) Note. For similar structures designed to protect flexible hose, rope, etc., from wear and abrasion, see Class 138, Pipes and Tubular Conduits, subclass 110, and Class 384, Bearings, subclass 24.
(4) Note. For bushings or lining thimbles, ferrules and rings having means for preventing abrasion of elements passing thereinto or therethrough but not limited to use with electric conduits, see Class 16, Miscellaneous Hardware, subclasses 2.1+ 108, and 109.
