Overview
The Proloc™ Camber Bar Attachment is a versatile set of steel sleeves that slide onto any standard Olympic barbell to convert it into a cambered bar. Created by the makers of Proloc™ Collars, this attachment drops the center of gravity of the weight plates, forcing the athlete to stabilize the load and improve their overall form. This tool is particularly useful for athletes with shoulder mobility issues, as well as home gym owners with low ceilings who need to perform overhead presses without hitting the overhead structure.

Performance Benefits
Joint Relief: Dropping the weight several inches below the main shaft takes significant pressure off the shoulders during squats, making it a valuable tool for rehab or lifters with limited mobility.
Stabilizer Recruitment: The "swing" or oscillation created by the cambered design introduces a chaotic element to the lift, forcing the core and smaller stabilizer muscles to work harder to keep the bar in a straight line.
Low Ceiling Solution: For home gym owners training in basements or garages, the cambered drop allows the plates to clear the floor while the bar shaft stays lower, enabling standing overhead presses in spaces with as little as 7-8 feet of clearance.
Portability: Unlike a dedicated 7-foot camber bar, these attachments can easily fit into a gym bag, allowing commercial gym members to bring specialty bar functionality to their local facility.
Installation and Assembly
The Proloc attachments are designed to be "locked down" to your barbell sleeves.
Slide on: Place the attachment over your barbell’s Olympic sleeve.
Secure: Use the included Proloc™ Strongman Collars to tighten the attachment in place.
User Tip: Some athletes prefer placing a small rubber micro-plate or a 5lb plate on the outside of the attachment and using their own heavy-duty collars (like Rogue Aluminum Collars) to ensure zero slip during heavy sets.
Maintenance and Care
Powder-coat Upkeep: Clean the black powder coat with a damp cloth and mild soap. Avoid metal brushes, which will scratch the finish.
Oxidation Prevention: Periodically apply a light coat of 3-in-1 oil or machine oil to the 12" loadable sleeves to prevent surface rust, especially in humid environments.
Hardware Check: Inspect the tightening stars on the Proloc collars regularly to ensure they are not stripping and provide a secure lock.
Warranty Information
The Proloc™ Camber Bar Attachment is typically backed by a Construction Warranty against manufacturing defects.
Coverage: Applies to the original purchaser.
Exclusions: Does not cover finish wear or damage caused by negligent use (e.g., dropping the bar directly onto the attachments).
Frequently Asked Questions (FAQ)
Q: Will these scratch my barbell? A: Because they are steel-on-steel, there is a risk of minor surface scuffing on your barbell's sleeves. To minimize this, ensure the attachment is tightened securely and not "sliding" during use.
Q: Do I need special plates? A: No. The 12" sleeves are standard Olympic diameter (50mm), compatible with all standard iron, bumper, or change plates.
Q: How does this compare to the Rogue CB-1 Camber Bar? A: The CB-1 is a dedicated, solid-welded 85 lb bar. These attachments are a more affordable, space-saving alternative that allows you to use your existing high-quality barbell.
Q: Can I use these for deadlifts? A: No. Cambered attachments are not designed for deadlifting as they would hit the floor before a full range of motion is achieved. They are optimized for squats, presses, and benching.
