Dryer-Ell 45-Degree Long-turn Dryer Elbow overcomes length of run issues and increases efficiency. The Dryer-Ell has a longer radius and smooth interior that reduces friction. It can be measured the same as straight pipe, eliminating the run-length reduction currently required for other elbows in most building codes. This is for 4" dryer duct.
Technical note: A pair of mated 45s will provide 6.25" of offset.
Tip: Any sheet metal screw will work to mate the sections, but the easiest are the black Pro-Twist Pan Head Framing Sharp Point Screw #7 x 7/16″, which are common with HVAC tradesmen.
Screws are not included.
