Measure the distance between your fence posts where the gate will be and subtract 2 inches. Cut five 2-by-4 boards to that length. Measure the height of the posts, subtract 4 inches, and cut three 2-by-4 boards to that length.
Lay two boards on the ground spaced far enough apart to cover the height of the fence post. Place a vertical board perpendicularly over each end of the horizontal boards. Make adjustments to the horizontal boards as needed to form a rectangle with the corners flush.
Drill two evenly spaced holes into each corner through both boards where they intersect. Slip the lag bolts up through the holes of the horizontal board and the vertical board. Secure the bolts with nuts to hold the rectangular frame secure.
Square the frame. Lay the remaining vertical board over the horizontal boards in the exact center of the gate. Drill two holes through each end of this board and into the horizontal boards and secure with lag bolts.
Flip the unit over and place the three remaining horizontal boards over the frame spaced evenly between the top and bottom horizontal boards. Drill a screw through each of the horizontal boards where they intersect with the three vertical boards.
Determine which side of the gate will hold the hinges. Align a caster under the bottom of the vertical board along the opposite end and attach it with screws. If you want added support, align and attach a second caster under the middle vertical board.
Lay the two hinges spaced evenly along the height of the gate opposite the caster end. Secure one side of the hinges to the gate with screws. Lift the gate and take it to the fence post.
Hold the hinge end of the gate to the post and lift or lower the end to make the gate level. Secure the hinges to the post with screws. Align and attach a gate latch to the opposite end of the gate and the opposite fence post.
