The cheapest piece of safety equipment in any gym, and the one most often skipped. Spring collars clamp onto a 50mm Olympic sleeve in a second, holding plates in place so a slightly uneven press does not send weight sliding off one end of the bar. KEY FEATURES Fits Olympic 2-inch (50mm) barbell sleeves One-handed squeeze-and-slide operation Sprung steel construction with a protective coating Fast enough to use between every warm-up set Essential for bench press, overhead press and rows Supplied as a pair PRODUCT OVERVIEW Spring collars are the fastest collars to use, which is precisely why they get used. A quick-release lever collar is more secure, but if changing it takes ten seconds per side, people skip it during warm-ups, and warm-ups are exactly when uneven loading tends to happen. A collar you will actually fit on every set is worth more than a better collar you leave on the floor. Their limitation is grip force under dynamic loading. Spring collars hold well for controlled work but can creep slightly under repeated impact, so for Olympic lifting or anything where the bar is dropped, a lever or locking collar is the better choice. For squats, presses, rows and deadlifts performed under control, spring collars are entirely adequate. TRAINING APPLICATION Fit collars for every set involving a loaded bar, without exception. The risk is highest on unilateral or slightly asymmetric movements: single-arm work, uneven bench press, overhead press with a drifting bar and bent-over rows. A plate sliding off one sleeve mid-rep instantly transfers the entire remaining load to the other side, which is how bar-related injuries usually happen. HOW TO CHOOSE? Choose spring collars for speed and everyday use. Choose quick-release lever collars where maximum clamping force matters, particularly for heavy or dynamic lifting. Most home gyms benefit from owning both: springs for warm-ups and accessory work, lever collars for heavy working sets. Note that these fit 50mm Olympic sleeves only, not standard one-inch bars. FAQs Will these fit a standard one-inch bar? No. They are sized for Olympic 50mm sleeves. Standard spinlock bars use threaded collars instead. Are spring collars secure enough for heavy squats? For controlled squats, yes. For dropping the bar or Olympic lifting, a quick-release lever collar provides more clamping force. How many do I need? Two, one per sleeve. They are supplied as a pair. Do they scratch the barbell? The coating limits marking, but any collar clamping onto a sleeve will show some wear over time. This is normal and does not affect function.
