Presto’s three ATRA® Anchor types are designed for maximum anchorage strength, connection certainty, and installation speed. One-piece polymer ATRA Speed Stake anchors are engineered for optimal performance and resistance to corrosive environments. Glass-fiber reinforced polymer (GFRP) anchors also offer corrosion resistant. ATRA Stake Clips with rebar or straight rod form flat head ATRA anchors. All of Presto’s ATRA anchors are designed with flanged arms for secure connections with GEOWEB cell walls and resistance to sliding and uplift forces–and all drive faster and easier than curved J-hooks.
