Innovative, lightweight aluminum ell that turns 90° within a 4 1/2" space. Great for use in tight turn locations like exterior walls with a Dryerbox. Also used in tandem with aluminum flex for a painless transition hose installation due to the swivel ends (two needed for this).  Not as efficient as the regular goose-neck adjustable Ell or our Long Turn Ells.
