I need to hide some cables under my standing desk, I tried duct tape and it lasted a couple of days, I tried gluegun...and that didn't work out either...anyone has this same issue and has figured out how to tape the cables (chargers, desk lamp, etc) to the table's undersurface firmly once and for all?
3M command adhesives are really great in my experience, I'm using their cord hangers [0] for cable management under my desk and haven't had any issues. The only thing that might be causing problems is if the bottom side of the desk is unfinished MDF, in that case any adhesive won't work since the fibers themselves are coming off. Painting the underside should solve that issue.
I ran into the same problem, and the main cause is that the downward force is able to slowly peel off any tape that is solely on the bottom of the desk. If the tape is extended onto the sides or top, it becomes much sturdier, because the tape would need to be dragged across the surface, rather than slowly peeled off. However, that makes the tape be much more visible.
I'd recommend instead adding some screw hooks to the bottom of the desk. The mechanical fasteners can be entirely on the bottom of the desk, and are sturdier I'm general than the tape.
For anyone wondering what "nuclear grade" means here, it's normal 8979 tape plus an assay for guaranteed low halogen content. This is desirable as halogens, particularly chlorine, are a major cause of metal corrosion. So guaranteeing your tape is low in them makes it better suited to uses where any corrosion that forms cannot be detected or repaired. Like a nuclear plant!
