In at least eight places, including product specs with material type, they are referred to as "rubber" when they are just cheap vinyl caps. The fact that 'Vinyl' work is also used, albeit less frequently, does not alter the fact that THIS IS NOT RUBBER and should not be mentioned anywhere, especially in the 'Material' spec!
