Barbell HMS Fitness ZG1000

The Barbell HMS Fitness ZG1000 is a pair of spinlock lock jaws designed for barbells with a 5 cm diameter. Supplied as a pack of two, these black lock jaws secure weight plates on the bar and contribute to stable load distribution during strength training sessions. Rubber inserts on the inner surfaces reduce slippage of plates and help maintain a firm hold during dynamic movements.

Advantages

ZG1000 lock jaws combine simple operation with durable construction. Their spinlock mechanism allows quick and secure weight changes while the internal rubber parts minimise movement between the collar and plates. Manufactured with attention to build quality, these collars are resistant to wear and provide reliable performance over repeated use.

Suitable for

• Home strength training with standard 5 cm diameter bars
• Commercial gym use for free-weight exercises
• Weightlifting, powerlifting and general resistance training
• Circuit training and classes that require frequent plate changes

Key specifications

• Type: Spinlock lock jaws (pair)
• Compatible bar diameter: 5 cm

How to use

Slide a lock jaw onto the end of the bar until it contacts the outermost weight plate, then rotate the spinlock mechanism clockwise to tighten and secure the plate. To remove or change plates, rotate the collar counterclockwise until loose and slide it off. Check the rubber inserts regularly for wear and ensure the collars are tightened before each set to maintain stability during lifts.

Usage recommendations

Use the ZG1000 collars with bars that match the specified 5 cm diameter and inspect the rubber inserts periodically. Tighten collars fully before performing dynamic or heavy lifts and replace worn collars to preserve safe and stable workouts.
