Best tape on the market!



Seriously good tape

Sean from St Louis, MO on 2/5/2018

If you think "any ol' electrical tape is electrical tape", this tape will prove you wrong. It's stretchier, more resilient to temperature changes, and longer lasting than cheap stuff by a long shot. Totally worth it in any application that you will be dealing with again. I've used this for a broad range of applications, and it holds up better than cheaper products. Quality adhesive and the tape itself resists becoming brittle and cracking like cheap tape. You won't regret the few extra dollars for the roll.

Pros: Stretchy, durable, UV/temp resistant


The definition of electrical tape.

Crutchfield Customer Review (What's this?)

The real deal. Sticky, Non-conductive. Comes in a decent case so it won't get dirty/grungy. If you are thinking of electrical tape, you are probably thinking of exactly this.



Great Tape
