Name: Edgeworks Usa. Descripton:The Knucklehead Edging product lines consists of our standard lawn and garden edging, garden decor, and custom designs series such as logos and other promotional images for landscape application. Made from HDPE plastic, Knucklehead edging will out last all the other curbing and edgings on the market today! Our patented product has optional features that include a weed barrier retaining system, housings for drip irrigation tubing and housing for low voltage wiring. Knucklehead edging products are preformed for quick and easy installation, has reinforced connecting joints and is available in a 3” profile and 5” profile. Staking is only required to hold the edging down and when the weed barrier option is added stakes may be eliminated all together. The Knuckle feature alone makes our product far superior to other plastic edgings. Not only attractive but functional too. The knuckle provides a guide for string trimming and removes the “wobble effect” that is common when installing other plastic edging. Knucklehead Edging is a premium edging.
