 Ground Wire Reel is made in stainless steel, so that it can be used in the area where high corrosion resistance is required, and it can be mounted directly to the grounded surface.

The stainless steel housing is the most significant.  The action of the retracting mechanism is much smoother and, the fact that your reel is rebuildable gives us an edge over the other reels.
