LC-206 CK2 Steel Auto-Lock Twist Karabiner 25 kN
Karabiners & Connectors (EN 362)

The PGTEC LC-206 CK2 is a galvanised steel auto-lock twist karabiner built to EN 362 for the harshest industrial environments where aluminium hardware would be too easily damaged. Forged from heat-treated carbon steel and hot-dip galvanised, the CK2 delivers 25 kN along the major axis, 10 kN across the minor axis and 10 kN on the gate, comfortably above the EN 362 minimum for class A connectors. The gate uses a triple-action twist-lock mechanism: pushing the gate in and twisting the sleeve opens it, and releasing the gate causes the sleeve to spring back and lock automatically. That means the karabiner cannot self-open from vibration, snagging or contact with steel, which is why it is the default connector on offshore, petrochemical, shipyard and heavy-construction sites. The oval D-body gives good loading geometry and the tapered nose clips easily into anchor slings, scaffold hooks and steel eyes. The hot-dip galvanising provides years of corrosion resistance in coastal, salt-spray and chemical environments, and the steel body shrugs off side-loads that would bend an aluminium unit. The CK2 is commonly used as the harness-end or anchor-end connector on the EAL4 twin-leg stretch lanyard, on scaffold hooks, on self-retracting lifelines and on horizontal lifeline brackets. Every unit is proof-load tested, batch-marked and CE labelled.
