How to Install a Tensar Polygrid Fence

Measure the length of the two wooden end posts you are using for the fence. Dig two post holes one-third the length of the posts plus an additional 3 to 4 inches, using hand-held post-hole diggers, or jobbers.

Place 3 to 4 inches of gravel into the post holes with a shovel. Set one of the posts in a hole. Hold it straight up and down as you check it for plumb with a carpenter’s level. Then add enough dirt into the hole to hold the post. Tamp the dirt around the post with a hand tamper. Finish filling the hole and tamp the dirt firmly into place. Set the second end post in the same manner.

Tie string around one of the end posts. Pull the string taut as you tie the other end to the other post. Use the string line to help you keep the fence line straight as you set steel fence posts in the next step.

Measure 6- to 8-foot intervals between the two end posts. Mark these intervals with spray-painted "X's."

Set steel fence posts at least 18 inches into the ground on the X's you marked in the previous step. Use a post driver to position them. The flange on the bottom of the post must be below grade level.

Cut 1-by-3-inch furring strips or similarly sized lumber to fit the length of the posts, using a circular saw. You need two boards per post.

Wrap Tensar Polygrid fence fabric around one of the end posts. Place a furring strip over the top of the fence fabric on the front side of the post. Using screws long enough to penetrate through the furring strip and at least 1 inch into the post, secure the furring strip and Tensar to the fence post. Secure another furring strip to the back of the post with Tensar sandwiched in between. Do not insert screws into the fabric.

Pull the fencing material tight to the first steel fence post. Sandwich the Tensar between two vertical furring strips. Attach the furring strips and Tensar to the post with wire ties wrapped around the furring strip. Insert ties through openings in the Tensar, but do not poke holes in it. Twist the ties as tight as possible with pliers. Tuck the ends of the wire ties back onto themselves so the ties cannot scratch an animal.

Continue hanging the Tensar on the remaining steel fence posts in a similar manner. Keep the fabric pulled taut as you work.

Wrap the Tensar around the remaining end post. Attach a furring strip to the front and back of the post as you did in Step 7. Cut any excess Tensar with a utility knife.
