Abstract: A metal fence post protective cap made of a flexible plastic material to fit snuggly on top of a T shaped cross section and uniformly spaced studs extending from one surface. The cap is formed with channels to receive the T shaped cross section and the studs with all of the channels being closed at the top. The T shaped cross section receiving channels are completely open at the bottom of the cap but the bottom of the stud receiving channel is partially closed with a retainer portion which engages and outer portion of a stud to resist accidental removal of the cap from the post. The retainer portion merges with a small lead in opening acting as a guide to align studs with the stud receiving channel during installation of the cap on the post.

Abstract: A unitary insulator of plastic material for supporting an electrified conductor wire in a horizontal position when the insulator is fastened to either a vertical post or is rotated slightly and is fastened to the diagonally extending wires of a chain link fence.

Abstract: A plastic insulator for holding an electrified conductor, and particularly a conductor of a tape configuration, in insulated relation to a fence post and in elevated position above the ground. The insulator includes a clamping arrangement releasably holding the conductor against axial or radial movement by a pair of conductor engaging members hinged together for movement between a tape receiving and a tape clamping position. The clamping arrangement includes a latch mechanism with a coating finger and a deflectable tab with an opening to receive the finger to prevent relative movement of the conductor engaging members and inadvertent opening of the clamping arrangement.

Abstract: An adaptor for converting an electric fence post insulator from a wire electric conductor support to a tape conductor support. The adaptor connects to the wire holding fingers of the insulator.

Abstract: An insulator and wire mounting structure for supporting an electrically conductive fence wire from a metal fence post having a generally T-shaped cross-section. The insulator and wire supporting member has a pair of leg portions which are deformable relative to each other to receive an intermediate portion of the T-post and after being brought into parallel alignment with each other receive a nut which threadably engages a thread set to tighten the mounting structure in position for supporting the wire.

Abstract: An electric fence insulator cap for mounting on U-posts of varying flange tip to flange tip widths and varying bight to flange depth in either of two 180.degree. oriented positions. The electric fence wire is held in a pair of slotted lugs for simple installation. The cap top is generally sloped to deflect rain with a central flat surface for impacting installation on the fence post.

Abstract: An electric fence insulator cap for mounting on various weight and flange configuration T-posts in any of four 90.degree. spaced positions. The electric fence wire is held in a pair of spaced slotted lugs for simple installation. The cap top is generally sloped to deflect rain with a central flat surface for impacting installation on the fence post.

Abstract: A molded one-piece electric fence post insulator which can be installed on a flat or round wood post with a single nail. A forward planar post engaging panel has a vertically extending wing at each lateral side. The wings extend forwardly of the panel plane from vertical hinge lines so that as the insulator is nailed against a round post, the wings engage the post to firmly hold the insulator against twisting, and as the insulator is nailed against a flat post, the wings fold rearwardly along the hinge lines presenting planar contact of the insulator with the post.
