1) If your deer fence is polypropylene and less than 500 feet long, and you see no need to defend it against falling tree branches, then you need nothing along the top.
2) If your deer fence is a polypropylene fence over 500 feet long, plan on putting a single line along the top for support. The line should not go around corners, across gates, or over 300 feet in a straight line. So when you have gone 300 feet, reached a corner, or reached a gate, terminate your run of line and start again. If any of these runs of line are very short (less than 50 feet) or go around a curve, use metal tie wire; otherwise use nylon monofilament --11 gauge for polypropylene fencing, 8 gauge for metal hexagrid fencing.
3) If your deer fence is a metal hexagrid fence, proceed as in (2) above, regardless of whether the fence is shorter or longer than 500 feet.
4) If you anticipate heavy deer impacts on a polypropylene fence, put one or two additional runs of nylon monofilament and/or tie wire through the mid-section of the fence, following the same rule for selecting monofilament versus tie wire that you used along the top of the fence.
5) Based on the above, calculate the number of feet of nylon monofilament (8 or 11 gauge) and/or metal tie wire that you will need. This calculation will tell you how many of the various spools should be added to the list of items in your shopping cart.
Line Terminators and Tensioners
1) The metal tie wire requires no special terminators or tensioners because it is tightened manually, it doesn't stretch, and it can be terminated by twisting it several times around itself. However, when a "run" of nylon line (either at the top or through the middle of the deer fence) extends 300 feet or reaches a deer fence corner, end, or gate, you need accessories to terminate this run. Plan on using two terminators for each run of nylon deer fence line, one of which will be placed at the beginning of the run and one at the end.
2a) If you are using U-bolt cable clamps, which are inexpensive and come in packs of 10, you will need one circular wire tensioner for each "run" of line in addition to the two cable clamps, and should also get one handle tool for tightening the circular wire tensioners, which are left on the deer fence and can be re-tightened if and when the nylon line stretches. Please note that the handle tool's design has been changed since our installation videos were made (it now has only one handle), but it works.
2b) If you are using oval metal sleeves (also inexpensive and also sold in packs of 10) you will need one circular wire tensioner for each run of deer fence line in addition to the two sleeves, and you will also need a special crimping tool for the sleeves as well as the handle tool (see note in paragraph 2a) for the circular wire tensioners.
2c) If you are using gripples you do NOT need any circular wire tensioners or handle tool, but you do need a gripple tensioning tool. In general, the gripples provide the most elegant but also the most expensive deer fencing solution, while the U-bolt cable clamps are the least expensive choice.
3) Using the information above, calculate the number of terminators you will need (two per run), adding any circular wire tensioners (one per run) and special tools that you may need, and enter these in the shopping cart..
Plan on attaching the nylon monofilament line and/or metal tie wire to the deer fencing with hog ring staples, using a hog ring stapler. (Alternatively, you can use strong 8-inch zip-ties, which are cheaper but which take much longer to fasten.) If the fencing is polypropylene use one staple or zip-tie per 1.5 feet of monofilament line or tie wire, while if it is metal hexagrid fencing use one staple or tie for every foot of monofilament line or tie wire.
