Safety clips, also called barbell collars, should be used on any loaded barbell where plates could shift or slide off during a lift. That includes squats, overhead presses, rows, deadlifts, and most other barbell movements. The one notable exception is the bench press when you’re lifting without a spotter, where skipping clips can actually be the safer choice.
Why Clips Matter on a Loaded Barbell
Weight plates don’t sit perfectly still on a barbell sleeve. Even small imbalances in your grip or stance can cause plates to drift toward one end. Once one side gets heavier, the bar tilts, more weight shifts, and within a second or two you’ve lost control of the load entirely. This is dangerous for you and for anyone standing nearby.
The National Strength and Conditioning Association (NSCA) requires athletes to use collars any time there is weight on the bar. That’s their blanket rule for supervised training facilities, and it reflects how seriously strength professionals take the risk of unsecured plates. Clips take a couple of seconds to fasten, and they eliminate a category of accident that’s entirely preventable.
Exercises That Always Need Clips
Any lift where the bar moves overhead or sits on your back is a high-priority situation for clips. Shoulder presses, push presses, jerks, and snatches all involve a barbell above your head. If plates slide during any of these movements, you’re dealing with a sudden, violent shift in load that can pull you sideways or send weight crashing to the floor. Squats carry a similar risk: the bar sits across your shoulders, and even a slight forward lean can start plates creeping toward one end.
Cleans, power cleans, and any Olympic lifting variation belong in this category too. These are fast, explosive movements where the bar travels a long distance in under a second. Plates that aren’t locked down will rattle loose quickly under that kind of acceleration. Children and newer lifters are especially vulnerable here, as injury data shows younger athletes have a higher incidence of weightlifting injuries related to dropping weight.
Barbell rows, lunges, and hip thrusts round out the list. Rows involve a forward-bent torso where gravity naturally pulls plates toward the ends of the sleeves. Lunges create side-to-side shifting as you step. Hip thrusts use a barbell across your lap, and if one side sheds a plate, the sudden imbalance can twist your spine. Even deadlifts, where the bar never rises above hip height, benefit from clips. You might get away without them on a slow, controlled pull, but the added security costs you nothing.
The Bench Press Exception
The bench press is the one major barbell exercise where many experienced lifters deliberately leave clips off, and there’s a good reason. If you get pinned under the bar with no spotter, your only escape route is tilting the barbell to one side so the plates slide off. This is sometimes called “dumping the weight,” and it only works if there are no collars keeping the plates in place.
This applies even when you do have a spotter. If the weight is too heavy for your spotter to help you lift off your chest, they can at least help you tilt the bar so the plates fall away. With clips locked on, that option disappears, and you’re stuck under a loaded bar with no way to reduce the weight. For solo bench pressing especially, leaving the collars off is a widely recommended safety practice.
If you bench inside a power rack with safety pins set at the right height, or on a bench with built-in spotter arms, this concern goes away. The pins catch the bar before it can crush you, so clips become safe to use again.
Types of Safety Clips
The three most common collar types are spring clips, plastic lock-jaw style collars, and screw-on collars. Each has trade-offs in grip strength, durability, and ease of use.
- Spring clips are the simple metal clamps you’ll find in almost every commercial gym. They’re cheap, nearly indestructible, and maintain consistent tension for years. Gyms report spring clips lasting a decade or more of daily use with no loss in grip. The downside is they require hand strength to squeeze open, which can be a problem for people with arthritis or grip limitations.
- Plastic lock-jaw collars (like the Rogue HG or similar brands) snap onto the bar with a lever mechanism. They grip well when new and are easier to operate than spring clips. However, the plastic wears down over time, especially in commercial gym settings. After a year or so of heavy use, many lock-jaw collars lose their grip and need replacing. For home gym use where they see less abuse, they can be a good option.
- Screw-on collars thread onto the barbell sleeve and tighten with a bolt or knob. They provide the most secure hold but take longer to put on and remove. You’ll see these more often on specialty bars or in powerlifting meets where maximum security matters and quick plate changes don’t.
When Clips Need Replacing
A collar that doesn’t grip the bar tightly is worse than no collar at all, because it gives you a false sense of security. Before you clip up, do a quick check. If a spring clip slides onto the sleeve without resistance, the spring has lost its tension and won’t hold plates in place under load. If the metal is bent, rusted, or visibly deformed, grab a different pair.
For plastic collars, the lever should snap firmly into the locked position and the collar shouldn’t rotate or slide when you push on it. If it wiggles or feels loose even when locked, the internal gripping surface has worn smooth. At that point, the collar is decorative, not functional. Most gyms cycle through plastic collars faster than spring clips for exactly this reason.
Machines and Dumbbells
Cable machines, plate-loaded machines like leg presses and hack squats, and Smith machines typically have their own built-in mechanisms to secure weight. You don’t need barbell clips on these. Dumbbells come as a single fixed unit or with their own threaded collars, so standard barbell clips don’t apply.
The one exception is adjustable dumbbells or loadable dumbbell handles where you slide plates on yourself. These absolutely need collars, just like a barbell. A plate falling off a dumbbell mid-curl or mid-press creates the same sudden imbalance and injury risk as an unsecured barbell.
