LEOPO No Drilling Window AC Bracket
This heavy‑duty steel bracket expands from 31.5″ to 41.7″ and fits exterior wall thicknesses of 2″ to 11″. It supports 5000–24000 BTU units and is suitable for most single or double hung windows in bedrooms, living rooms, and offices. Best for long-term, tool-free setup in rental or traditional homes. A key limitation is its maximum weight of 300 lbs, which may require careful load assessment for larger units.
