What eye screws to use to hang heavy objects from ceiling
I want to suspend a pair of vintage Bose 901 speakers from a wood rafters ceiling using eye screws and chains. This is apparently a common way one used to mount them. Each speaker is quite heavy (35 lbs / 16 kg) so I would use four chains each. (See attached instruction manual that just shows how it would be done). But I always have trouble with this:
I would use 16lb capacity light #14 jack chains, four individual lengths. Maybe I can get slightly stronger gauge but since four chains I would think I don’t have to use super heavy duty.
what size eye screw would you recommend that I use? The speaker cabinets are a bit more than 1/2 inch walnut laminated particle board and each eye screw would go in there. Would I get heavy gauge ones?
same eye screw in ceiling as in speaker or longer ones in ceiling?
for each eye screw, what size pilot hole would I drill?
I’m so paranoid that they would pull out of the speakers or not get good enough grip there or in the ceiling timbers. I always have trouble figuring out pilot hole sizes for important eye screws like this. Any advice would be appreciated!
