4 Feet of 3M NST Heavy Duty Black Heat Shrink Tubing 2:1 ratio 1-1/4" 1.25"

Description

This is for 4 feet of heavy duty 3M heat shrink tubing taken from a 50' roll.  Made of neoprene, this is thicker than most other heat shrink tubing on ebay. Think of bicycle inner tube thickness.  The shrinkage ratio is approximately 2:1.  The 1.25" is measured as the diameter when the tubing is opened into a round cylinder shape.  When it's laying flat it's about 2-1/8" wide.  I can provide continuous lengths up to 50 feet - just ask.
