Rated 3 out of 5 by from 1000ft spools not sturdy enough for shipping Lately every time I order a 1000ft spool it is cracked in have when I receive it. I try to order only 500ft spools for this reason.
Date published: 2021-01-06
Rated 5 out of 5 by from Good Wire This is very good wire. The one thing I would change is making the insulation on the red conductor more visible. It looks too clear.
Date published: 2019-03-29
Rated 5 out of 5 by from Solid Thermo Wire Bought for industrial purposes, works great. Stripping can be messy as it is cloth insulation.
