Supplies for Installing T Posts
- T-posts (6.5–8 ft, with anchor plate) – quantity = fence length ÷ spacing
Example: 100 ft at 10 ft spacing ≈ 10–11 posts - End/corner assemblies (recommended): treated wood posts + brace rails or H-braces
- Gate hardware (if a gate is planned)
- T-post caps (safety, highly recommended around horses)
- T-post driver (manual “pounder”) or sledgehammer
- Measuring tape & marking paint/flags
- String line or laser for straight runs
- Digging bar (to probe/pilot in rocky soil)
- Gloves (leather)
- Eye protection
- Hearing protection (when driving many posts)
- Steel-toe boots
- Soil tamper (firm up around loose posts)
- Portable water (soften hard ground)
How to Install a T Post
- Gather tools: T-post, measuring tape, string line, T-post driver, level, gloves/eye/ear protection, optional post cap.
- Mark the line & spacing: Run a tight string for a straight fence. Mark post locations (common spacing: 8–12 ft; closer for high tension).
- Set orientation: Point the studs/lugs on the T-post toward the fence wire (usually the livestock side) to help hold wire in place.
- Start the post: Stand the T-post on the mark with the anchor plate at the bottom. Press or tap to seat it.
Tip: In rocky ground, pre-pilot with a digging bar; in very soft ground, tamp soil around the post after driving for a tighter set. - Drive the post: Slide the T-post driver over the top and drive straight down until the anchor plate is fully below grade (often 18–24″ in the ground, or to local code/frost depth).
- Plumb it: Check with a level; correct by tapping from the side if needed.
- Cap it (optional but safer): Add a T-post cap/insulator to protect humans and animals.
- Attach fence: I won’t get into the details of this because it’s dependent on your type of fence, but this is what you’ll do next! If you
