Barbell collars are small accessories that play an important role in strength training. Designed to secure weight plates to a barbell, collars help prevent plates from shifting during lifts, improving both safety and stability. Whether you're performing heavy squats, Olympic lifts, bench presses, or general strength training, the right collars can help keep your setup secure and your focus on the lift itself.
With several types of collars available, choosing the right option depends on your training style, equipment, and preferences. This article explains the different types of barbell collars and the factors to consider when selecting them.
What Are Barbell Collars?
Barbell collars are devices that attach to the sleeves of a barbell to hold weight plates in place. While some lifters may occasionally train without collars, using them is generally recommended, particularly when lifting heavier weights or performing exercises that involve dynamic movement.
Collars help:
- Reduce plate movement during exercises
- Improve balance and stability on the bar
- Prevent plates from sliding off the sleeves
- Enhance safety during training
Do You Need Barbell Collars?
For most strength training setups, the answer is yes.
During exercises such as squats, deadlifts, bench presses, overhead presses, and rows, collars help keep plates securely positioned. They become even more important during explosive movements such as cleans, snatches, and high pulls, where the barbell experiences greater acceleration and impact.
While some lifters may occasionally skip collars for lighter lifts or quick plate changes, collars are generally considered a standard part of a safe training environment.
Common Types of Barbell Collars
Spring Collars
Spring collars are among the most common and affordable options. They use a simple spring-loaded mechanism that compresses when squeezed and grips the barbell sleeve when released.
Pros:
- Affordable
- Quick to install and remove
- Widely available
Considerations:
- Can become difficult to squeeze over time
- May not hold plates as securely as premium designs
- Less ideal for heavy or highly dynamic lifting
Clamp Collars
Clamp collars use a locking lever or latch mechanism to secure the collar around the sleeve.
Pros:
- Strong holding power
- Quick to install and remove
- Helps minimize plate movement
Considerations:
- Typically cost more than spring collars
- Quality can vary between manufacturers
Threaded Collars
Threaded collars are commonly used on 1" standard barbells and dumbbell handles with threaded sleeves. Rather than relying on a spring or clamp mechanism, these collars are tightened onto the threads to secure weight plates in place.
Pros:
- Secure fit on threaded bars
- Affordable
- Common on standard 1" size equipment
Considerations:
- Slower to install and remove than spring or clamp collars
- Only compatible with threaded bars
- Not intended for Olympic barbell sleeves
Verify Barbell Compatibility
Before purchasing collars, confirm that they match your barbell's sleeve diameter.
Most modern Olympic barbells use 2" sleeves (approximately 50 mm) and require Olympic collars. Standard-size barbells use smaller sleeves and require collars designed specifically for those dimensions.
Consider Your Training Style
For exercises that involve more movement and bar speed, such as cleans, snatches, and high pulls, many lifters prefer quality clamp collars because they typically provide a more secure hold than standard spring collars.
General Strength Training:
For traditional strength training, including bench presses, squats, rows, and machine-loaded barbells, quality spring collars are usually sufficient for keeping plates secure during workouts.
Olympic Weightlifting & Dynamic Training:
For exercises that involve greater movement and bar speed, such as cleans, snatches, and high pulls, many lifters prefer quality clamp collars because they typically provide a more secure hold and help minimize plate movement during explosive lifts.
Choosing the Right Barbell Collars
Barbell collars help keep weight plates secure, improve stability, and support safer training. When choosing collars, consider your barbell's sleeve design, training style, desired level of security, and ease of use.
Whether you choose spring collars, clamp collars, or threaded collars, selecting the right option can help create a safer, more stable, and more efficient training experience.
