  • Tighten the cable clamps securely to prevent them from popping out.
  • Pull the cable tight before fully tightening the turnbuckle to reduce the amount of tightening needed.
  • Check the gate alignment and tension after initial tightening; you may need to make further adjustments after a few days.

Common Mistakes to Avoid

1. Incorrect Gate Alignment

Reason: The gate isn't perfectly aligned in its frame, causing uneven pressure and premature sagging.
Solution: Adjust the gate hinges and latches to ensure the gate hangs evenly and straight within its frame.

2. Using the Wrong Size Anti-Sag Kit

Reason: An improperly sized kit won't provide adequate support, leading to continued sagging or even damage to the gate or frame.
Solution: Measure the gate carefully and select an anti-sag kit specifically designed for its dimensions and weight.

3. Insufficient Tightening of Fasteners

Reason: Loose screws or bolts on the anti-sag kit or gate hinges will allow the gate to sag over time.
Solution: Ensure all screws and bolts are tightened securely, using appropriate tools and checking regularly for looseness.
