And if there's already a megalug and/or thrust block on the 90 below, they're superfluous code-wise. Only need 1 of the 3 methods of joint restraint.

Has the floor already been poured @ the run-in? Lamar Vaughn ---- Chris Cahill <[email protected]> wrote: > I don't know much about UG, looking for a little help.
