Assembly – Part 1 (Steps 1‑3)

1
Position & Plumb Legs (A1‑A4)

Mark the concrete along the fence at 0 ft, 4 ft, 8 ft, and 12 ft. Stand each leg (letter facing forward) on those marks.

  1. Use the 4 ft level on the front face of A1. If the bubble drifts, slip a cedar shim under whichever corner fixes it.
  2. Repeat on the side face, then on A2‑A4.
  3. They do not need to be perfect – within ¼ in is plenty.
⚠️ Don’t skip shimming
Poorly plumb legs translate into a tilted bar top that will slide drinks.
2
Attach Front Top Rail (B)
  1. Clamp B flush to the top of A1‑A4 on the front faces.
  2. Check level from A1 to A4.
  3. Predrill two ⅛ in holes through B into each leg, 1 in from top edge & 2½ in below.
  4. Drive eight 3 in screws.
3
Attach Back Top Rail (C)

Repeat Step 2 against the fence side using rail C, keeping it flush with leg tops.

Assembly – Part 2 (Steps 4‑6)

4
Install Foot Rail (D)
  1. Measure 12 in up from concrete on each leg front and draw a line.
  2. Clamp D so its top edge aligns with that line.
  3. Predrill and drive eight 3 in screws – two per leg.
5
Add Blocking (E1‑E3)

Stand each 14 in block between rails B & C with top edges flush.

  1. Position E1 at 2 ft, E2 at 6 ft, E3 at 10 ft from the left end.
  2. Screw through rails into block ends (2 screws per end, 12 total).
6
Install Kickers (E4 & E5)

Kickers stop the bar from rocking forward.

  1. Place E4 at the 4 ft leg: long point on rail C, short point on a solid fence stud ≈ 16 in above.
  2. Predrill through both ends and fix with 3 in construction screws (2 per end).
  3. Repeat with E5 at the 8 ft leg.
💡 Removal later
Back screws out and the kickers lift free – no marks left but two small holes in the fence stud.

Assembly – Part 3 (Steps 7‑8)

7
Attach Bar‑Top Boards (F1 & F2)
  1. Lay F1 & F2 flat, edges touching, centered front‑to‑back.
  2. Clamp the pair together to keep the seam tight.
  3. Starting at the left, pre‑drill every 24 in along rails and blocks (one screw line per board).
  4. Drive 3 in screws – approx 24 total.
⚠️ Face‑screwing tips
Angle screws slightly toward center of the rail to reduce risk of splitting.
8
Sanding & Staining

Sanding

  1. Grinder: knock sharp corners off legs & top.
  2. Orbital sander: 120‑grit over entire top until smooth; wipe dust.
  3. Switch to 180‑grit; quick pass for buttery finish; wipe again.

Staining (after PT lumber dries ≈ 7 days)

  1. Stir stain – do not shake (bubbles).
  2. Brush a thin coat with the 3″ brush, following grain. Keep wet edge.
  3. Wait 10 min, then back‑brush drips.
  4. Optional second coat after 2 h for richer color.
  5. Light use after 24 h; full cure 72 h.
💡 Disposal
Lay stain rags flat to dry before trash – prevents spontaneous combustion.

Done! 🥂

Kick back and enjoy your new outdoor bar. Removal is as easy as undoing the fence screws and walking it away.
