Hampton Fitness is an American Made 28.5" diameter Olympic Power Bar made from high tensile strength steel with a PSI rating of 185,000. A medium diamond knurling pattern offers a secure grip when performing heavy pulls such as deadlifts and the absence of center knurling is less abrasive when performing power cleans. Self lubricating bronze bushings make for consistently smooth rotating weight plate sleeves to lessen torque on the wrists. The plate sleeve assembly includes an integrated snap ring design for maximum strength and maintenance free performance. And the entire bar from shaft to sleeve is finished in a durable nickel plated hard chrome. The IB-86 is an ideal general purpose weightlifting bar for commercial clubs, school weight rooms and sports performance centers and is also appropriate to be stocked in cross-training facilities for use with bumper plates. Olympic plates, bumper plates, and olympic collars NOT included.
