Key Features & Specifications
Made in the USA: Precision CNC-machined from 6061 aircraft-grade aluminum.
Redesigned Mechanism: The 2.0 version features a refined lever system that provides a higher clamping force while remaining easy to engage and disengage with one hand.
Internal Protection: Includes a rubberized interior lining to prevent metal-on-metal contact, protecting your barbell's sleeve finish.
Weight: ~0.5 LB per pair (Lightweight yet extremely strong).
Width: 1.5” (Occupies minimal space on the loadable sleeve).
Compatibility: Designed for use with all standard 50mm Olympic barbell sleeves.
Finish: Available in multiple anodized colors (Black, Red, Blue, Silver, etc.) with laser-etched Rogue branding.
Performance Benefits
Maximum Grip Strength: Unlike plastic or spring collars, the aluminum construction does not flex, providing a consistent "lock-down" that prevents plate drift during high-rep sets or heavy drops.
One-Handed Operation: The lock-lever is designed for ergonomic, rapid transitions, making these ideal for timed CrossFit® workouts or competitive weightlifting sessions.
Durability: Aircraft-grade aluminum ensures that the collars will not crack or degrade over time, even in high-volume commercial facilities.
Low Profile: At only 1.5 inches wide, these collars maximize the available loadable sleeve length for heavy lifters using wide bumper plates.
Maintenance and Care
Cleaning: Periodically wipe the interior rubber lining with a damp cloth to remove accumulated chalk or dust, which can reduce the friction grip.
Pivot Point: If the lever becomes stiff over years of use, a single drop of dry lubricant on the pivot pin will restore smooth operation.
Storage: When not in use, store the collars in a dry environment. The anodized finish is highly resistant to corrosion but can be scratched if dropped repeatedly on abrasive surfaces (like concrete).
Frequently Asked Questions
Q: Will these fit my specialty bar (e.g., Axel bar)? A: These are designed for standard 50mm (2") Olympic sleeves. If your specialty bar has standard-sized sleeves, they will fit. They will NOT fit standard 1" bars.
Q: Do they stay on during heavy drops? A: Yes. The 2.0 mechanism was specifically tested to remain secure during high-impact Olympic lifting and functional fitness drops.
Q: Are they sold as a pair? A: Yes. All Rogue Aluminum Collars are sold and shipped as a pair.
