    Black Diamond RockLock Screwgate

    I am a Paraplegic wheelchair User and I needed a secure “cleet” for all my keys, car fob, beer openers , Disability radar key, torch and numerous other charms etc.
    The climbing Black Diamond RockLock Screwgate, is absolutely secure and looks after all my important keys, security gate fobs etc.
    I have had NO ISSUES whatsoever with this piece of equipment.
    I did not realise how strong and “chunky” it is until I received it in the post along with another of my choice.
    Very fairly priced too, I will be back for other items of secure keepers.
