Heat shrink tubing 6.4mm
An essential component if you've used copper shielding or conductive shielding paint inside the control cavities of your guitar.
Especially useful to insulate the braided ground wires in guitars such as Les Paul and SG models, and for covering the solder joints on the output jack.
The 6.4mm tubing is also great for tidying up and protecting the three braided wires from your Les Paul/SG toggle switch.
Simply slide the tubing over your wire, and use a heat gun or the shaft of a soldering iron to shrink to the correct size.
6.4mm tubing shrinks down to 3.2mm
