Quoted from ForceFlow:The ones I have are metal.
The 12ft I linked to is the same model I have and it's a metal one. I didn't have the 25ft at my fingertips to grab the model number off of it, but I'm pretty sure the one I linked to is metal too.
That's the first time I heard about them using chromed plastic.
I haven't seen a metal 25' Stanley in 20 years. I've purchased 70-100 of them in that time. Only 25' for me, for the 3" stock.
