The collar for thousands of weight changes
You know the drill: Spring collars that slip from your hands when your forearms are pumped. Or cheap collars that give up after a few months of box operation. The Lock-Jaw Pro are built for exactly this constant use. The lever mechanism works with one hand – pull open, flip over, done. The plates sit rock-solid and don't shift, no matter how dynamic your training. Ideal for WODs, Olympic Lifts and daily athlete rotation.Built for box operation
The Pro version is our recommendation for CrossFit boxes and gyms with high traffic. The high-quality plastic withstands enormous pulling forces – the collars literally bite into the barbell sleeve. At the same time, the smooth inner coating ensures they glide cleanly over the bar when open. That saves time and nerves during quick weight changes. With 50 mm inner diameter they fit all Olympic barbells – long bars and dumbbells. Delivered in pairs, ready to use.Technical Specifications
