My rails measure out at 15-1/8" long, 1" wide, and about 11/16" deep. There are two holes, drilled and tapped for 1/4-20NC screws, on 14-1/2" mounting centers. Not sure what you mean by length of peg - if it's the length of the footpad beyond the depth (11/16") of the rail, that's about 2-3/4". Hope this helps. Dennis

: Does anyone know the dimensions (mounting locations, length, depth of rail,
: length of peg, etc.) for the Yakima adjustable/non-sliding footbraces?

: I checked the Yakima site and although the mention other yak equipment, there
: was no sign of the footbraces. I'm trying to plan (first pass
: approximation) the location of the footpegs in my daughters yak, but
: without the dimensions there is not much I can do without the braces.
