Our take on the Custom Portable AC Window Kit for Casement Windows

This is a custom-cut acrylic panel that lets you vent a portable air conditioner through a casement (crank) window. Each panel is CNC machined from 1/4-inch clear plexiglass to the window's measurements, so it seals the opening instead of leaving gaps around a universal fabric or plastic insert. A quick-attach vent plate locks into the panel for hose hookup, and installation is non-permanent, so it comes out without damaging the frame. It suits renters and owners with crank windows who want a cleaner, more rigid seal than a one-size-fits-all kit.

Questions and answers

How do I measure my casement window for this kit?
Measure the window opening the panel will sit in, following the seller's measuring guide, and account for the crank hardware. Custom panels are cut to the numbers you supply, so double-check before ordering.
Will it work with any portable AC hose?
The quick-attach vent plate is designed for standard portable AC exhaust hoses. Check the hose diameter against the plate opening before ordering.
Can I remove it in winter?
Yes. The installation is non-permanent, so the panel lifts out and the window closes normally when the AC is stored.
Does it fit sliding or double-hung windows?
No. It is made for casement (crank) windows; other window types need a different kit.
Does the clear acrylic block heat or UV?
It is plain acrylic, not insulated or UV-treated glass, so it blocks airflow and rain but still lets light and some heat through.
