We sell two styles of heat shrink tubing, with and without an adhesive lining. For general rig making the regular tubing is the most economical solution while for making heavy duty stiff single and double hook rigs we recommend the adhesive lined clear tubing.
Adhesive lined sold by the 300 mm (12"), Non adhesive tubing sold by the metre (39 inches).
Spike's tip
If you don't have a hot air gun you can use your wife's hairdryer to shrink the tubing, make sure you put it back before she finds out!
