About these itemsAll barbells are constructed from high - strength solid steel. They are designed to bear extreme weights, with load capacities ranging from 500 lbs to 1000 lbs, offering excellent load - bearing and high tensile strength for various training needs.Feature rotation systems (either 360° rotating sleeves or a combination of needle bearings and brass bushings) that reduce friction. This ensures smooth, snag - free movement during fast lifts like snatches and clean & jerks, enhancing training efficiency and safety.The handles have an ergonomic 1.1 - inch diameter with 1.2 - mm deep diamond knurling. This provides a firm grip, prevents slipping, distributes wrist and forearm pressure, reduces fatigue, and improves stability during high - intensity workouts.Designed with a 2 - inch sleeve diameter, they are fully compatible with mainstream weight plates. A high - strength collar lock system is included, which is easy to install and secures the plates tightly, enhancing workout safety.Suitable for a variety of strength - training exercises, including explosive lifts and stability - focused powerlifting moves. They are also great for cross - training, catering to users at different fitness levels.Key DifferencesItem Model NumberOB - 47, RS1200, OB - 72, RS1800, RS2200.Load CapacityOB - 47, RS1200, OB - 72: 500 lbs / 227 kg (approx. 226.8 kg for RS1200).RS1800: 700 lbs / 317.51 kg.RS2200: 1000 lbs / 453.59 kg.Bar LengthOB - 47, RS1200: 4 ft / 1200 mm.OB - 72, RS1800: 6 ft / 1820 mm (1800 mm for RS1800).RS2200: 7 ft / 2200 mm.Sleeve LengthOB - 47: 7.48 inch / 190 mm.RS1200: 6.69 inch / 170 mm.OB - 72: 12.6 inch / 320 mm.RS1800: 12.01 inch / 305 mm.RS2200: 16.34 inch / 415 mm.Knurling WidthOB - 47: 7.87 inch / 200 mm.RS1200: 7.48 inch / 190 mm.OB - 72: 15.94 inch / 405 mm.RS1800: 7.48 inch / 190 mm.RS2200: 7.68 inch / 195 mm.Grip Spacing/WidthOB - 47: Grip Spacing 9.37 inch / 238 mm.RS1200: Grip Width 11.42 inch / 290 mm.OB - 72: Grip Spacing 9.84 inch / 250 mm.RS1800: Grip Width 13.78 inch / 350 mm.RS2200: Grip Width 16.54 inch / 420 mm.Bar and Sleeve FinishOB - 47, OB - 72: Chrome - plated finish for bar and sleeves.RS1200, RS1800: Ceramic coating and electrophoretic finish.RS2200: Red ceramic coating for bar, electrophoresis coating for sleeves.Net WeightOB - 47: 16.4 lbs / 7.44 kg.RS1200: 22.05 lbs / 10 kg.OB - 72: 25.68 lbs / 11.65 kg.RS1800: 33.07 lbs / 15 kg.RS2200: 44.09 lbs / 20 kg.SpecificationsOB - 47Item Model Number: OB - 47Bar Finish: Chrome PlatedSleeve Finish: Chrome PlatedBar Length: 4 ft / 1200 mmSleeve Length: 7.48 inch / 190 mmKnurling Width: 7.87 inch / 200 mmGrip Spacing: 9.37 inch / 238 mmPlate Compatibility: 2 inch / 50 mmPSI: 92,000Max Capacity: 500 lbs / 226.8 kgGrip Diameter: â1.1 inch / 28 mmMain Material: 45# SteelNet Weight: 16.4 lbs / 7.44 kgItem Dimensions (LxWxH): 47.24 x 2.56 x 2.56 inch / 1200 x 65 x 65 mmRS1200Item Model Number: RS1200Bar Length: 4 ft / 1200 mmSleeve Length: 6.69 inch / 170 mmKnurling Width: 7.48 inch / 190 mmGrip Width: 11.42 inch / 290 mmPSI: 94,000Load Capacity: 500 lbs / 227 kgNet Weight: 22.05 lbs / 10 kgItem Dimensions (LxWxH): 47.24 x 2.95 x 2.95 inch / 1200 x 75 x 75 mmOB - 72Item Model Number: OB - 72Rod Length: 6 ft / 1820 mmSleeve Length: 12.6 inch / 320 mmKnurling Width: 15.94 inch / 405 mmGrip Spacing: 9.84 inch / 250 mmNet Weight: 25.68 lbs / 11.65 kgItem Dimensions (LxWxH): 72.05 x 2.76 x 2.76 inch / 1830 x 70 x 70 mmRS1800Item Model Number: RS1800Bar Length: 6 ft / 1800 mmSleeve Length: 12.01 inch / 305 mmKnurling Width: 7.48 inch / 190 mmGrip Width: 13.78 inch / 350 mmPSI: 94,000Load Capacity: 700 lbs / 317.5 kgNet Weight: 33.07 lbs / 15 kgItem Dimensions (LxWxH): 70.87 x 2.95 x 2.95 inch / 1800 x 75 x 75 mmRS2200Item Model Number: RS2200Bar Finish: Red Ceramic CoatingSleeve Finish: Electrophoresis CoatingBar Length: 7 ft / 2200 mmSleeve Length: 16.34 inch / 415 mmKnurling Width: 7.68 inch / 195 mmGrip Width: 16.54 inch / 420 mmPlate Compatibility: 2 inch / 50 mmPSI: 120,000Max Load Capacity: 1000 lbs / 453.59 kgGrip Diameter: â1.1 inch / 28 mmBushings: 2 Brass BushingsBearings: 2 Needle BearingsMain Material: 45# Steel with Quenching TreatmentNet Weight: 44.09 lbs / 20 kgItem Dimensions (LxWxH): 86.61 x 2.95 x 2.95 inch / 2200 x 75 x 75 mmPackage ContentAll Models1 x Barbell Bar2 x Electroplated Spring Collars1 x Color Workout Poster (Workout Guide Poster for RS1200, RS1800, RS2200)
