An incredibly nice feature of the F'tech CF-series speaker bananas and coax/RCA adapters is they can be loosened or tightened. Loosen to remove or install then tighten when fully seated... all by hand, no tools necessary. All CF series adapters have a threaded collar/sleeve assembly that the CF body tightens around the OD of the RCA/coax jack and the speaker bananas use a threaded CF body collar that threads a pin up/down thru the center of the cross-cut banana plug expanding it after fully seated in the binding post. When I first saw these at shows around the country 6-7 years ago the F'tech reps were installing them then swinging small components around over their heads by the cables. Yes, they hold fast when tightened tho no way I'd attempt lassoing with my gear. Yours maybe but not mine ;-) I do suspect each cable adapter when fully tightened capable of holding probably +/- 20-30 pounds pretty easily.
