Angle-iron Posts and Extenders |

Angle-iron Posts and Extenders Metal angle-iron posts provide suitable support for plypropylene fencing. If alternated with our round metal posts they also provide adequate support for metal hexagrid fencing. These posts are suited to any type of soil. It may be helpful to use a pry bar (item 15-03PB) in addition to a manual post driver (item 15-05) to get them in. If your soil is heavy clay, the frost line is over 2 feet down, and you are concerned about frost heaves, use 10-foot posts (like 15-01B30 below) or else use our handy 4-foot extenders (item 15-02K below) to get the bottom of your post below the frost line. The 9 and 10 footers we offer (items 15-01 and 15-01B30 below) have black, 12-gauge 1.25-inch sides at 90 degrees to one another, with holes located along one side at 2-inch intervals. They do need periodic inspection for rust and touching up with rust-preventive paint (item 15-08). These posts are made of high-carbon rail steel and are able to absorb an impact of 50,000 pounds per square inch without breaking, so they provide more strength per unit of weight than the average steel posts used for fences. For instructions on how far apart to space these posts and how to set them in, go to our written installation instructions or see our video on installing angle-iron posts. Our 4-foot angle-iron post extenders (item 15-02K) can be used to make a fence taller. Each of these sturdy extenders is identical in horizontal cross-section to our 9 and 10 foot angle-iron posts, and each comes with 2 nuts, bolts, and washers for attaching it to a 9 or 10 footer. By adding this extender, your angle-iron posts can go 3 or more feet into the ground and still stand plenty tall enough to support deer fencing with an effective working height of up to 10 feet. However, it is not recommended that polypropylene or hexagrid deer fencing be attached above the fence’s normal height. Rather, 11-gauge nylon monofilaments (see Deer Fence Installation: Monofilament Lines for Deer Fence) should be hung and tightened using zip-lock ties (item 17-04), circular wire tensioners (item 16-09), and monofilament line terminators such as items 16-08 and 16-081. These zip-lock ties should be strung through the holes in the angle-iron posts, arranging things so that there is a 4 to 6-inch space between each pair of lines. In this way the fence’s effective height can be extended up to 3 feet.
