The inner rail is 11/64" tall. Low-friction UHMW strips in the bottom of the track let the plane glide smoothly. Screws for mounting the track to a shooting board are included.
The 16" track provides ample travel for most end-grain shooting. The extra length of the 24" track is useful for jointing work or making a two-sided miter shooting board that lets you handle any grain orientation.
Made in Canada.
