Abstract
A power transfer unit is disclosed. In a first implementation of the disclosed power transfer unit, a tubular assembly of the power transfer unit includes an encapsulated elbow hinge design with a reduced profile that permits substantially off-center installation of the housings of the power transfer unit. In a second implementation of the disclosed power transfer unit, the tubular assembly includes an inverted, telescoping tubing design that does not come apart during installation and use, and in some implementations may act as a stop for a closable member.
