Page fencing is the standard fence used for a variety of animal control. We use 949-12 Hi-tensile page fencing, 9 being the number of horizontal wires, 49" is the the height, and 12" is the distance between the stays or vertical wires. 

      It is a 12.5 gauge wire, which though smaller diameter than the older 949-16 which is a 9.75 gauge wire, is a stronger wire with "spring" to absorb the shock of an impact and is also triple galvanized which makes it much less prone to rusting. It is also more economical than the older 949-16 so you get a better quality page fence for less money.
