Store a barbell above your power rack, converting it into a useable pull-up station - for smarter storage AND a bigger back. The 3D-printed Hydra Barbell Holder Rack Attachment is made to fit perfectly on true 3" x 3" tubing with 5/8" holes but will fit smaller racks with a DIY shim. With a 500lb capacity, this versatile storage solution will hold barbells up to 32mm in diameter.Place your barbell across the power rack for a makeshift pull-up station, ideal for lifters with a Lat Pulldown attachment. We recommend mounting the holder toward the front or rear of your rack to avoid epic fail videos. Hardware NOT included. Sold in pairs.IMPORTANT: Avoid doing butterfly/kipping pull-ups from a barbell in the Hydra Barbell Holder Rack Attachment, as upward motion could cause it to jump out of the holder and cause injury.
