    ISC Oval Supersafe Carabiner 3 Pack

    $77.95
    In stock

    The KL121  Oval is a standard size oval karabiner with an effective working length of 85mm (3.4”).  Many industrial Oval Karabiners have an offset shape, in order to bias (offset) the load towards the spine (the strongest part of the karabiner), to achieve additional major axis strength.  The KL121 however is ideal when load centralisation, correct orientation and optimal loading are the top priorities, to enable balance in a system.

    The KL121 is the first ISC karabiner that is available with the option of a screw-in/screw-out captive pin.  The screw-in captive pin can easily be installed/removed as required, using a standard 2mm Alen/Hex Key, making it quick and easy to swap lanyards etc., as and when they need to be replaced.

    Nice carabiner. Tight fit in certain places

    Bought these as a cheaper alternative to the DMM Ultra O. The have worked out well, though I think I still prefer the Ultra O slightly, mainly due to the fact that I have found the ISC ones to be a bit snug in certain applications.
