Overview
The Rogue Infinity Socket Pull-up Curl Bar is a specialized pull-up station that integrates the ergonomic benefits of a cambered (curved) barbell into your Rogue rig or rack. Featuring the same 28.5MM diameter and precision-formed curves as the standard Rogue Curl Bar, this attachment is designed to alleviate wrist strain and offer a variety of hand positions. Specifically built to fit a 43" span on an Infinity Series unit, it uses a modular socket system to ensure a stable, zero-rotation pulling experience.
Key Features and Specifications
Construction: Solid round steel, precision-formed in the USA.
Bar Profile: Cambered design based on the Rogue Curl Bar for ergonomic grip variance.
Compatibility: Optimized for any 43" space on a Rogue Infinity Series rig or rack (2x3” uprights with 5/8” hardware).
Diameter: 28.5MM.
Knurling: Battle-tested Ohio Bar knurl pattern; extended to the inside portion of the bar to facilitate close-grip chin-ups.
Finish: Shaft features a Black E-Coat—a high-durability, automotive-grade finish known for its superior adhesion and corrosion resistance.
Product Weight: 17 LB (total for bar and sockets).
Hardware: Includes (2) textured black mounting sockets and (4) 0.625" x 3.5" bright zinc bolt assemblies.
Spin Control: Features two button-head set screws to lock the bar into the sockets, preventing rotation (7/32” Allen wrench required).
Manufacturing: Proudly Made in the USA (Columbus, Ohio).
Performance Benefits
Ergonomic Joint Relief: The cambered curves of the Rogue Infinity Socket Pull-up Curl Bar allow for semi-supinated or semi-pronated grips, which help reduce the linear stress on the wrists and elbows common with straight-bar pull-ups.
Custom Grip Widths: With knurling that reaches the inner camber, athletes can transition between wide-grip pull-ups and neutral-style close-grip chin-ups with a secure, consistent feel.
Enhanced Texture: The Ohio knurl provides a "medium" level of tackiness that is effective with or without chalk, ensuring a secure grip during high-volume gymnastic sets.
Superior Finish Protection: The electrically applied E-coat creates a uniform, chip-resistant surface that offers significantly better protection against moisture and oxidation than standard powder coating.
Maintenance and Care
Knurl Cleaning: Regularly use a synthetic or nylon bristle brush to remove sweat, chalk, and skin debris from the knurling. This prevents moisture entrapment and keeps the E-coat finish in optimal condition.
Hardware Check: Periodically inspect the 5/8" mounting bolts and the 7/32” Allen set screws. Dynamic kipping and pulling can cause hardware to settle; ensuring the set screws remain tight is critical to preventing the bar from spinning.
Drying and Storage: Wipe the bar dry after intense sessions. For garage gyms in high-humidity areas, regular cleaning with a damp cloth followed by drying will extend the "like-new" aesthetic of the bar.
Surface Protection: Although E-coat is exceptionally durable, avoid metal-on-metal impact from weighted vest buckles or dip belt chains. Touch up any deep scratches with a rust-inhibiting paint.
Warranty Information

Frequently Asked Questions
Q: Will this bar rotate while I am doing pull-ups? A: No. The Rogue Infinity Socket Pull-up Curl Bar includes a locking socket system with set screws that fix the bar in place, ensuring it remains stationary during use.
Q: Can I mount this on a 3x3" Monster Lite rack? A: No. While the hole spacing is similar, this version uses 3.5" long bolts intended for 2" deep Infinity uprights. For 3x3" racks, you will need the Rogue Monster Lite Socket Pull-up Curl Bar.
Q: Is the knurling too aggressive for high-volume work? A: The knurling is borrowed from the Ohio Bar, which is considered a "medium" texture. Most athletes find it provides a secure grip without causing excessive hand tearing during high-rep sets.
Q: Why would I choose a cambered bar over a straight bar? A: Cambered bars allow your hands to sit at a more natural angle, which can significantly reduce joint strain for athletes with previous injuries or those looking for greater training variance.
