The adjustable angle of the hook allows the user to fine-tune and adjust the size of the retaining ring they need to remove. The XLC TO-S100 is designed to be particularly robust and durable, so it can easily withstand being thrown in a toolbox and living a hard life in the workshop - an ideal buy and use forever tool. The easy-grip vinyl-coated handle allows you to have a strong purchase for those tough to undo threads.
