    hi,the trick to having hang off a wall is to realise that the weight is mostly tear weight and not shear weight,to fix a weighty item to a wall you must first assertain if the wall can carry or hold the weight first,when the situation of tear weight comes into play the top fixing simply pulls out of the holding substrate,this is common due to underestimating the load capabilities of the backing ,shear weight is a lot more as the weight has to be over 50 times the weight of force downwards to directley cause a fault
    kind regards

    Hi,

    Can you get Tapcon fasteners? I've use them for any application where I need to fasten something block, brick, concrete to mount heavy shelving, conduit, junction boxes, etc.

    Hell, I've even used them to fasten a couple 2x's to a wall to use as a step up to work on wiring in a joist space where a ladder wouldn't fit.

    One of their strongest features is that you can easily remove them with a screwdriver or nutdriver/ratchet.

    Tapcons rock.
