Eightnoo Audio 1/4" Right Angle Plugs TS Mono Heavy Duty Style for Speaker Cables- Male 1/4 Inch Phono 6.5mm Phone Plug , Great for the DIYer (Pack of 5)

Overview: Excellent heavy duty construction. The maximum cable diameter is 7mm, about 0.28 inches. I would recommend using no more than 1/4 inch cable, and a few inches of heat shrink tubing as a strain relief. The tip connector has a hole to solder the wire. The ring connector does not have a hole, but there's plenty of room to wrap the conductor strands around it for soldering. The ring connector doubles as the cable crimp clamp, so having a hole would weaken it. There is an internal plastic isolator between the tip and ring solder contacts . Package included: *x adapter
