Barbell Spinlock Collars HMS ZG1500 for 5 cm Bars, Pack of 2

Barbell Spinlock Collars HMS ZG1500 for 5 cm Bars, Pack of 2 are spinlock-style locking collars designed to secure weight plates on Olympic-style bars with a 50 mm (5 cm) sleeve diameter. Each pack contains two metal spinlock collars with an internal rubber insert that improves grip on the bar and helps stabilise plates during lifting. These HMS ZG1500 collars are intended for use in strength training, powerlifting and general gym work where rapid, tool-free plate fixing is required.

Advantages

The spinlock mechanism provides quick and intuitive tightening by hand, eliminating the need for additional tools. An internal rubber part increases friction between the collar and the bar sleeve, reducing plate movement and noise during exercise. The collars are manufactured from durable materials to withstand repeated use and provide long service life in home or commercial gym environments.

Suitable for

• Securing weight plates on 5 cm (50 mm) diameter Olympic-style barbell sleeves
• Home gyms where fast plate changes are needed
• Strength training and powerlifting sessions
• Commercial gym stations requiring reliable plate retention

Key specifications

• Locking type: spinlock (hand-tightened)
• Compatibility: bars with 5 cm (50 mm) sleeve diameter
• Pack contents: 2 collars
• Material: metal body with internal rubber insert for stability
• Finish: corrosion-resistant surface treatment for extended durability

How to use

Slide the collar onto the bar sleeve until it rests against the outermost weight plate, then rotate the spinlock until it is hand-tight and the rubber insert contacts the sleeve. Ensure the collar is snug enough to prevent plate movement but avoid excessive force that could damage threads or the rubber insert. To remove or adjust, rotate the collar in the opposite direction until loose and slide it off the sleeve.

Usage recommendations

Check collars for wear of the rubber insert and secure fit before each training session. Clean the sleeve and collar contact surfaces periodically to remove dust and chalk. Replace collars if metal threads or the rubber insert show significant wear to maintain safe plate retention.
