Hijacker TM Pier Bolsters
The HijackerTM Pier Bolster is made of 7,500 psi high-strength grout, is disk-like in shape and contains 12 gauge galvanized looped tie wires for installation.The high-strength grout supports the weight of the cage and will not shatter should the cage strike the casing or some other object. Because the bolsters are tied to the cage, the possibility of them becoming detached is eliminated.
This product has been well received by the structural engineering and construction communities. It achieves a result that has long been sought by structural engineers.
