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 installed with just one hand. Square corners surrounding the locking pin area deploy built-up debris.
As part of your climbing system, any karabiners should be visually and manually inspected before use and after any significant incident e.g. a fall, to ensure they work as intended. Any maintenance including cleaning should follow the manufacturers guidelines. If you are in any way concerned about the condition or action of the karabiner you should retire it from use immediately.
