How to Install a Prefab Fence

Lay out the area you wish to enclose with your prefabricated fence. Mark the area on the grass with spray paint. Measure the posts' width. Start on one end of the laid-out area and mark a fence post width on that end. Then, measure the width of the fence panel and mark that on the spray paint line. Add the post and panel widths together and work your way along the spray paint marking. Each mark indicates a post location.

Dig post holes at each post mark along the spray paint line, using a post hole digger. Make the holes approximately 12 inches wide and 30 inches deep. Fill each hole with 6 inches of gravel, then insert a post in each hole.

Measure down 2 inches from each posts' top edge and mark it with a pencil. Make this measurement on each side of the post, to which a panel bracket will be mounted.

Measure from the panel's top rail to the panel's middle rail and transfer this measurement to the panels. Measure from the middle rail's top to the bottom rail's top and transfer this to the posts as well.

Line up a bracket's top edge with the top mark on a post. Secure it in place with the provided screws. Line up a second bracket's top edge with the middle mark on the same post and secure this bracket in place with the provided screws. Line up a third bracket's top edge with the bottom mark on the same post and secure that bracket in place. Repeat with the remaining posts and brackets, lining up one bracket on each mark.

Mix concrete according to the manufacturer's directions. Pour the concrete into the first post hole, filling it up to about 3 inches below ground level. Measure the length of the post sticking up above ground level. Make sure each post extends up to the same height as you install them. Hold a level against the post and adjust it so it stands straight up and down.

Set the panel's rails in the appropriate brackets on the first post. Ask a friend to hold the panel's free end up while you drive the supplied screws through the brackets' screw holes and into the panel.

Position the panel's free end in the second post's brackets. Hold a level against the second post and adjust it so it stands straight up and down. Drive screws through the second post's brackets and into the panel. Pour concrete into the hole, stopping once it is 3 inches from ground surface.

Lay the second panel's rails on the second post's other set of brackets. Drive screws through the brackets' screw holes and into the panel. Set the panel's rails into the brackets on the third post. Level the post and secure the panel in place. Pour concrete into the post hole. Continue to work your way around the prefabricated fence layout until you reach the end.

Push a fence post topper onto each fence post. Once the concrete hardens, finish filling in the post holes with soil and spread grass seed over it.
