Large anchor post is 43.30 inches in length. (For use with 15.75" and 22")
Small anchor post is 18.50 inches in length. (For use with 9.5" only)
Anchor posts tek screw to the side of the rib (bracket) on the back of the edging. A minimum of 2 per section is recommended. Additional anchors can be secured at the ends of the panels and at each join.
The anchor post (no rib needed) works to use if you need additional posts for the 9.5" edging and does not require the use of a rib.
