I would want to install the elbow myself...would you access from the front, back, or underneath? I've never really inspected the dry.
I could shorten the length, but it was very difficult to install in the closet. I left a bit longer to ease in fastening the Periscope to the back of the dryer.
If installing the elbow won't be too difficult, I may re-order it and give it a shot. IIRC, it was about $40, which sounds like a rip for such a simple metal duct. Has anyone installed one of these on a SQ, or would know how to do so?
