There are several ways to reinforce a fence gate to keep it from sagging. A section of preassembled fencing can be used as a gate as long as extra reinforcement is used. Here’s how to go about it:
- Cut the panel to the correct size for the gate opening.
- Rip 2” thick pressure treated lumber to the width of the existing rails (stringers) on the gate.
- Lay the gate on a flat surface, and square it up.
- Measure the distance between the top and bottom rails.
- Cut the boards to length so they are a tight fit between the rails on each end of the gate.
- Secure the two vertical framing boards even with each end of gate using corrosion resistant screws.
- Measure and cut a diagonal support board to fit snuggly inside the opposing corners of the gate frame.
- Screw the diagonal support in place to transfer the weight of the gate to the hinge side and keep the gate from sagging.
- Screw the pickets to the diagonal gate support to provide more support strength.
- In addition, wide gates can be reinforced using an anti-sag kit consisting of two corner brackets, a steel cable, and a turnbuckle to tighten the cable as needed.
