Im going to be getting some heat wrap for my header. I was just curious as to how it stays wraped. Do you have to clamp the end of it. or does it just some how not come unwraped. ????

 

different brands have different methods of wrapping around and staying. none that i know of have a clamp however. some are self-adhesive, others just tend to stick to itself without the need of adhesives... static/small fibers maybe?

this site has some info you might read through
