Stove-top type pole guards have been around for ages. Robert was the first to design and manufacture one for the consumer. Pole guards work, as long as you place them high enough on the pole. Your pole guard should be placed no lower than 48-inches at the top of the guard. This also means your rope winder will need to be placed above the guard. Two styles available, for the 2-inch square pole, and the round, which fits a variety of size poles thanks to Roberts ingenious adjustable plate design. This product has been improved by the Troyers with the new "snake sniffer" holes which are placed on the top plate. The idea of these holes is that a snake climbing the pole, will stay inside the guard, reaching the top, and not being able to get thru will abandon.
