Stone Harbor Hardware, Heavy Duty Handrail Bracket (Matte Black)

What is the length from the top of the bracket where the two screw holes are located to the bottom of the bracket where the one screw hole is located?

What are the spacing of the holes? (Top holes from each other, and top to bottom holes)

Do these come with the strap to attache the rail to the brakcet? there is no picture of the strap.

The title color says "antique brass" yet the color name says "black." Which is it?
