The Pro Series Power Cage is a ruggedly built piece of equipment that is designed to give you the most space possible, while providing a safe environment to exercise. Get your strength and conditioning work done with multiple types of training that include – strength training, body weight training, resistance band training, and circuit training. Competitors have released Power Cages with a less stable frame that feature 2” x 2” upright poles. We directly responded by adding thicker gauge steel and increased the width and depth of the upright poles by half an inch. This rack now features a 2.35” x 2.35” frame. The complete set of upgrades include – a more stable frame with 2.5” x 2.5” upright poles, a higher gauge steel, and we included more accessories – 2 x Circle Dip Bars, 1 x Multi-grip Pull Up Bar, 2 x Safety Bars with J-hooks or 2 x Safety Straps with J-hooks. You can add larger attachments like the Cable Crossover and Lat Pulldown machine, which we specifically designed for the 2.35” x 2.35” upright poles. You can add more accessories to the rack – Olympic style barbell holders, J-hooks, Spotter arms and Weight plate holders. Safety bars or straps are absolutely necessary when weightlifting without a spotter. Safety straps inherently provide more safety because of its ability to absorb shock during weight drop. The non-rigid design of straps allows shock to be spread across the length of the strap vs bars, which take a majority of that impact at the point the bars meet.
