The super safe ISC HMS karabiner is lightweight but is still rated with an impressive breaking strength. Ideal on any climbing system its impressive breaking strength gives you additional confidence. The larger more rounded basket works well when using an advancing pulley under a hitch whilst the smaller crotch area helps prevent karabiner rotation and subsequent side loading. It is good for use on climbing lines up to 13mm.

The drop forged body is manufactured from high quality aluminium and an anodised coating is added to the smooth rumbled body. 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.
