All I found that was any use was the nut that slides into the extrusion. I would like to have found t-bolts but could not. I will probably just model a stud onto the nut and call it a t-bolt. I assume they must have something like that. I like to keep it real
They have a CD design library but it only works with AutoCad (as far as I can tell), which I have but do not use so I am avoiding it. I will take another look at that though.
I tried to download their catalog so I could just model from specs. Although I am on a very fast connection, the catalog is 44mb and was only downloading at about 40kb/sec so I abandoned that.
