Cutting a 4-Foot Gate Opening into an Existing Woven-Wire Garden Fence with Bolt Cutters: Braced 5-Inch Posts First, Staple Before You Cut, and Six Tight Wraps per Line Wire

Set and brace both gate posts before touching the wire, staple the fence to them, and only then cut. With 24-inch bolt cutters, snip the vertical stays between the line wires, cut each line wire at the center of the opening, and wrap each tail around its post and back onto itself with six tight wraps.

Can you cut a gate into a stretched woven-wire fence without losing tension?

Yes, if the new gate posts carry the load before any wire is cut. Set two braced posts, staple every line wire to them, then cut. The staples and posts hold the stretch, so the rest of the fence stays tight and only the opening goes slack.

The USDA NRCS Washington woven wire fence specification requires every line wire to be dead-ended on gate, corner, or pull posts. At an end point, you remove vertical stays, cutting them between the line wires, then double wrap each line wire around the post, staple it, and twist it back on the stretched wire with at least six tight wraps.

The USDA NRCS Iowa barbed and woven wire fence standard calls for wood gate posts at least 5 inches across the top, set at least 36 inches deep, or 2-1/2-inch steel pipe. It requires bracing on both sides of gate openings and says gates under 100 pounds can hang from single properly installed end posts with at least two hinges and a latch.

Gate Opening Spec for a 48-Inch Gate

Part	Spec	Why
Gate posts	5-in. top, 36 in. deep	Iowa NRCS minimum
Bracing	Both posts	Required at gate openings
Staples	45°, not driven tight	Washington NRCS spec
Line wire tail	About 22 in. each side	From a center cut
Tie-off	1 wrap plus 6 tight wraps	Fits the tail length
Gate weight	Under 100 lb.	Single posts can carry it

A center cut gives each side half the opening, about 24 inches minus clearance, which covers one wrap on a 5-inch post (about 16 inches) plus six tight wraps. The spec's double wrap needs longer tails, so splice on extra wire if you want it.

Materials and Tools

• 24-inch bolt cutters for the line wires and stays
• Two 5-inch treated gate posts and bracing lumber or brace wire
• 9-gauge galvanized fence staples, 1-3/4 inches or longer
• A 48-inch gate with two hinges and a latch
• Fencing pliers, a post-hole digger, a tamping bar, safety glasses, and gloves

Cutting Steps

1. Mark the opening. Measure the gate plus the hinge and latch gaps your hardware calls for, and mark both post centers along the fence.
2. Set and brace the posts. Dig both holes at least 36 inches deep beside the fence, tamp the backfill, and brace each post away from the opening.
3. Staple the fence. Drive a staple at 45 degrees over every line wire on both posts, leaving room under the crown.
4. Cut the stays. With the bolt cutters, cut each vertical stay inside the opening between the line wires and pull the pieces out.
5. Cut the line wires. Hold each line wire and cut it at the center of the opening so both tails are the same length.
6. Wrap the tails. Wrap each tail once around its post, staple it, and twist it back onto the stretched line wire with six tight wraps.
7. Trim the ends. Snip any loose ends so nothing points into the opening.
8. Hang the gate. Mount the hinges on one post and the latch on the other, then swing the gate to check clearance.

Wear eye protection for every cut, since a tensioned wire can spring back when it parts.

Gate Retrofit Mistakes

• Cutting the wire before the posts are set and stapled, which drops tension on the whole run
• Skipping the braces, so the gate posts lean in within a season
• Cutting stays at the line wire knots, leaving sharp stubs on the tails
• Hanging a heavy gate on light posts

Hole depth and backfill are covered in digging 48-inch gate post holes by hand. To build the gate itself, see building a 36 x 42 inch 2x4 garden gate frame, scaled to the wider opening.

To screen the gate's lower half against rabbits, check the hardware cloth mesh size and gauge guide.

If a tail comes up short, add length with a Western Union splice on a broken woven-wire line wire.

FAQ

Can I use T-posts as gate posts?

It's not a good idea. Iowa's standard calls for wood posts at least 5 inches across or 2-1/2-inch steel pipe at gates.

What size bolt cutters do I need?

A 24-inch pair cuts common fence line wires and stays; check the jaw rating against your wire gauge.
