The main construction lemma in Calegari and Gabai's proof of Marden's Tameness Conjecture can be replaced by an applicable version of our theorem.This is the version published by Geometry & Topology on 12 September 2006Geometric Topology57M50, 30F40Existence of ruled wrappings in hyperbolic 3-manifoldstext
