An Australian friend and concrete contractor, developed the patented “peg” puller for the Australian market. Construction Accessories’ initial product offering, the JackJaw® 100 concrete stake puller, was based on the peg puller. Since then, Bob has designed over 40 additional models to extract not only concrete form stakes, but also T fence posts, sign posts, ground rods, tent stakes, real estate signs, drill rods for nuclear density gauges, erosion control mat anchors and more!
