    cable clip, 7mm, mounted Cable clips - wide "C"-model, with extra rib.
    Available in various materials and/or colors, in a wide price range.

    Typically used to organize a length of power cable. Select your size, by rolling up the cable in a bundle and determine the "chamber room" needed.
    Use this to organize your cable, without needing to use knots or ties - which in the end could even damage the cable cores.
    Use 2-sided self-adhesive tape to attach a cable clip to a larger device.

    Cable clip, 7mm, 19x25x2Access our Cable Clips, for 7mm cable (approx), in 2 sizes.
    Shown here, is a cable clip for up to 7mm (thick) power cable, with 2 off 19x25mm storage chambers for the cable loops.
    (Larger size available and more sizes to follow).


    Door hook, sample Door hooks, for flat-top doors.
    Available in various materials and/or colors, in a wide price range.

    Typically used on plywood or "particle board" cabinet doors, as often used in bedrooms: contact us if you'd need a special size or model.

    Please note, that the top of the door needs to be a straight & flat door, due to the design of the hook: the back end of the hook is 6mm short - so that the door would be able to close, as long as it raises more than 6mm over the top of the cabinet (see the photo, on the right, for illustration).

    The wide top of the hook disperses the load over the relatively soft plywood material and prevents damage to the door, that you'd otherwise get from the metal hook of the clothes hanger, when that is hooked onto the door directly.

    Maximum load is relative to the chosen material (and the door in question).

    Givi case rack, with anti-loss rings mounted. Other items, that might interest you.
    Products for other uses, available in various materials and/or colors, in a wide price range.

    Cable clip, 7mm, 19x25x2Anti-loss ring for Givi rack's rubber bumpers.
    Anti-loss ring for Givi rack's rubber bumpers. You might recognize this, if you're an owner of a motorbike with a luggage rack.

    I've frequently lost those small rubber bumpers, intended for the top case, from the luggage rack of my motorbike. It's a Givi rack and it's perfect ... apart from the holes with which the Givi rubber bumpers are held in place: these are produced just too large & they hardly clamp the rubber bumpers at all.
    These anti-loss rings solved the problem.
