Think Fencing has a technologically advanced design. Durable product that looks good, and forever eliminated painting. Presumably manufactured by laser as slots for pickets are clean with no salvages or errors in spacing. Once the first panel is erected, construction thereafter is repetitious but exacting with care needed to keep the spacing uniform and posts straight and true. Definately within the capabilty of a concentious handyman. The Kookaburra design has the wow factor and the community universally expressed admiration.
