Developed to help contractors and installers get a firm anchorage for steel lawn edging in poor ground conditions, this Pin and Sleeve Accessory can be easily fitted to Classic, Heavy Duty, and Pro-Edge Steel Lawn Edging without any modifications. The sleeve is a small plastic piece that fits on the spike portion of the edging. A piece of 10mm diameter rebar (not included) is then slipped through the opening on the sleeve. This system considerably reduces the need for haunching, and is not necessary in normal ground conditions.  You can use as many as needed.
