Barbell collars might seem like a minor detail in your home gym setup, but choosing the wrong ones can lead to frustrating workouts, wasted money, and even potential safety hazards. A good set of collars will keep your weight plates securely in place, allowing you to focus on your form and push your limits. A bad set will constantly slip, interrupt your flow, and potentially lead to uneven loading and injury. This barbell collars buying guide covers the common mistakes people make and how to avoid them.
Mistake #1: Choosing the Wrong Size Collar

Phone Case GiftThey pick the model · 2 minutes Code FIRST15GIFTThis is the most common, and easily avoidable, mistake. Barbell collars are not one-size-fits-all. You need to match the collar to the diameter of your barbell sleeve. Here’s what to look for:
Olympic vs. Standard
- Olympic Barbells: These have a 2-inch (50mm) sleeve diameter. Almost all Olympic-sized collars are designed to fit this standard. If you’re buying a collar described as “Olympic,” you’re 99% likely to be fine. However, always double-check the product description to confirm the 2-inch compatibility.
- Standard Barbells: These have a 1-inch (25mm) sleeve diameter. These are less common in serious home gyms, but still widely used. Standard collars are not compatible with Olympic barbells.
Threaded vs. Smooth Sleeves
While less common now, some older or very inexpensive barbells use threaded sleeves and spin-lock collars. These are not compatible with any of the clamp-style collars we’ll discuss below. You’ll need collars specifically designed for threaded bars. We strongly recommend upgrading to a barbell with smooth sleeves for versatility and safety.
How to Avoid the Mistake:
- Know Your Barbell: Before you even start browsing, identify whether you have an Olympic or standard barbell. Measure the sleeve diameter if you’re unsure.
- Read the Specs: Always, always, read the product description carefully. Look for the sleeve diameter compatibility. Reputable manufacturers will clearly state this.
- Check Reviews: Skim through customer reviews. If there are consistent complaints about fit, steer clear.
Mistake #2: Prioritizing Price Over Functionality
Barbell collars are one of those items where spending a little more upfront can save you a lot of headaches (and potential injuries) down the road. The cheapest collars are often made from flimsy materials, have weak clamping mechanisms, and wear out quickly.
Spring Collars: A Budget Option, But Limited
Spring collars are the most affordable option, and fine for very light weight or beginners. However, they have several drawbacks:
- Weak Clamping Force: They don’t provide a very strong grip, especially as the spring weakens over time.
- Easy to Damage: They can be easily bent or distorted if dropped or mishandled.
- Limited Lifespan: The spring tension degrades with repeated use.
Clamp Collars: The Superior Choice
Clamp collars offer a much more secure hold and are generally more durable. There are several types:
- Plastic Clamp Collars: These are a step up from spring collars. They’re lightweight and easy to use, but can still be prone to cracking or slipping under heavy loads. Look for models with a robust locking mechanism.
- Metal Clamp Collars: These are the most durable and secure option. They provide a rock-solid grip and are built to withstand years of heavy use. Aluminum is a popular choice for its combination of strength and light weight.
How to Avoid the Mistake:
- Set a Realistic Budget: Don’t skimp on safety. Budget at least $20-$40 for a decent set of clamp collars.
- Read Reviews Carefully: Pay attention to reviews that mention slippage, durability, and the quality of the locking mechanism.
- Consider the Material: Opt for metal clamp collars if you’re lifting heavy or plan to use them frequently.
Mistake #3: Overlooking the Locking Mechanism

Types of Locking Mechanisms
- Cam Lock: This type uses a cam lever that, when tightened, applies pressure to the barbell sleeve. Cam locks are generally very secure and easy to use. Look for models with a smooth, positive locking action.
- Screw Lock: These collars use a screw to tighten the clamp. They can be very secure, but require more effort to tighten and loosen.
- Snap Lock: These collars have a spring-loaded snap that engages with a groove on the barbell sleeve. They’re quick and easy to use, but not as secure as cam or screw locks.
Key Features to Look For
- Solid Construction: The locking mechanism should be made from durable materials, such as steel or aluminum. Avoid plastic mechanisms, as they’re more prone to failure.
- Positive Engagement: The locking mechanism should engage firmly and securely. There should be no play or looseness.
- Easy to Use: The locking mechanism should be easy to operate, even with sweaty hands.
How to Avoid the Mistake:
- Examine the Mechanism: If possible, inspect the locking mechanism in person before buying. Look for solid construction and positive engagement.
- Read Reviews: Pay close attention to reviews that mention the ease of use and security of the locking mechanism.
- Test the Lock: If you’re buying online, check the return policy. When you receive the collars, test the locking mechanism thoroughly before using them with weight.
Mistake #4: Ignoring Collar Weight and Profile
While the primary function of a barbell collar is to secure the weight plates, its weight and profile can also impact your training experience.
Collar Weight
Most collars add minimal weight, but the difference can be noticeable, especially when working with lighter loads. If you’re performing exercises where precise weight increments are crucial (e.g., linear progression in strength training), consider the collar weight. Metal collars will weigh more than plastic or spring collars. Look for models where the weight is clearly stated.
Collar Profile
The collar’s profile (how far it extends from the barbell sleeve) can also be a factor. A bulky collar can interfere with your grip or range of motion, particularly on exercises like deadlifts or cleans. Low-profile collars are less likely to cause interference.
How to Avoid the Mistake:
- Consider Your Training Style: If you’re a competitive powerlifter or Olympic weightlifter, collar weight and profile are more important.
- Read the Specs: Check the product description for collar weight and dimensions.
- Look at Photos: Examine product photos to get a sense of the collar’s profile.
By avoiding these common mistakes, you can choose barbell collars that will enhance your training experience, improve your safety, and last for years to come. Remember to prioritize functionality, durability, and a secure locking mechanism. A good set of collars is an investment in your home gym and your fitness journey. Consider upgrading your barbell as well if you’re still using one with threaded sleeves.
