V rail - slotted - 10 1/2"

I was pleasantly surprised when the v rail that was shipped to me was black in color instead of the brown one that is depicted on the website. It was also nice that both sae and metric fasteners were supplied with it.

This is a well-designed and executed rail. The slots let you position the rail conveniently relative to your telescope rings, and it is long enough to enable balancing your scope while the mount fully grips the rail. It seems to be machined from a solid block of Al, is very solid (no flex), and is finished nicely.
