Mini split wall sleeve alternatives?
I feel like installing a mini split is a little like learning to mud drywall. Once you’ve got the job done, you know enough to do the job.
New question: most of the DIY kits include a wall sleeve which seems like a good idea for protecting the lines as they traverse the wall. However, with all my insulation/rainscreen whatnot, those sleeves are too short.
Is anyone aware of a longer sleeve (9”) or have you created your own alternative?
