A Carabiner Designed for Extreme Environments
The O’SMITH 3-MATIC is a high-strength steel carabiner, ideal for pulley systems, anchors, and abrasive material connections. Its symmetrical shape ensures optimal positioning and even load distribution. Unlike aluminum, steel bends before breaking, providing greater resistance to shocks and heavy loads.
Enhanced Safety with Triple-Action Locking
Its 3-MATIC automatic locking system prevents accidental openings while remaining quick and smooth to operate. The Keylock system eliminates snagging issues, making it easier to detach from anchor points. For those looking for a lighter alternative, the O’LIGHT 3-MATIC aluminum carabiner is a great solution.
