Field Guardian(R) Pipe Clamp Insulators (12-Packs) Install this insulator and get your horses' respect by mounting a scare wire. Our special insulator attaches to the side of your pipe panels without drilling a hole in the pipe. The clamp can be mounted on the horizontal or vertical section of the panel. The hot wire can be positioned as needed, a point midway up is preferred, although stallions may need a high wire to keep them from "necking" over the fence. Place it on both sides of adjoining pastures to reduce horse mischief to a minimum. We strongly suggest using polyrope or 1/2" tape to prevent injuries caused by hot wire. These insulators are an economical and practical way to protect your pipe panel fences. Sizes and specifications The pipe clamp insulators are 3.5" inches in length and they adjust for pipe diameters from 1 1/2" up to 1 5/8". (In order to make them fit 1 7/8" pipes, you will need to get 1.5" screws - not included in these). These sizes should fit most pipe panels, heavy duty fences as well as some cyclone fence posts. The pipe clamps are constructed of a high grade of poly plastic with UV inhibiters and flex agents added. This means that they will last for years without cracking; however, this also means that they cost a bit more than T-post style snap on insulators. Installation Instructions Select the location for the insulator. Snap the clamp over the pipe. If you are using the clamp on small diameter pipe, use the short screw in the top hole. If you are using it on a 1 7/8" pipe, use the longer screw in the bottom hole. Tighten the screw to fix the position on the pipe. Do not over-tighten.
