The ISC Twister karabiner is a strong and lightweight karabiner that has a captive eye and built-in swivel. It is ideally shaped to use with a flip line or side lanyards and the smooth ball bearing swivel system eliminates the need for a second separate swivel in the climbing system. The acute angle of the basket helps any captivated rope or sling gravitate towards the strong spine of the karabiner.

The drop forged body is manufactured from high quality aluminium. An anodised coating is added to the smooth rumbled body and the ISC innovative blind nose design helps minimise the risk of any snagging or plucking damage to your climbing line.

The patented ISC triple lock gates utilise stainless steel springs to ensure a long life under extreme conditions and are almost impossible to open accidentally, yet once mastered they can easily be installed with just one hand.
