Securely held in place by barbed anchoring stakes, ALUM-EDGE is made of an aircraft-grade aluminum alloy with a minimum lifespan of 27 years, with no need for painting, maintenance, rust, or replacement. ALUM-EDGE is lightweight and easy to handle, comes in extended lengths, and features a unique telescopic design for clean, quick, and easy installation. The ALUM-EDGE profile has a rounded top, eliminating the need to cut off protruding edges that could cause injury. It also prevents damage to lawnmower blades, providing a reinforced area that supports heavy machinery.
