Thermwell ACB160H Steel Ac Window Support 160 Lb

Product Description

The THERMWELL ACB160H is a heavy duty steel universal air conditioner window support bracket designed to hold window AC units weighing up to 160 pounds, covering units in the 12,000 to 24,000 BTU/h range. Built for all-weather durability, this bracket installs completely from inside the home, eliminating the need to lean out the window during installation. A precision bubble level is integrated into the unit to ensure the correct mounting angle for proper condensate drainage. HVAC technicians and experienced DIYers use this bracket as a standard part of window AC installation to reduce stress on the window sill and frame.

The ACB160H is suited for residential window air conditioner installations where a secure, long-lasting support solution is needed. Its universal design accommodates a wide range of window AC units in the 12,000 to 24,000 BTU/h class. The all-weather steel construction holds up in outdoor-facing conditions, making it appropriate for ground-floor and upper-floor window installations alike. The inside-only installation method is particularly useful in multi-story buildings where exterior access is limited or unsafe.

Installation Notes

Installation is performed by an HVAC technician or qualified installer working entirely from inside the structure. Power off and unplug the AC unit before mounting or adjusting the bracket. Use the integrated bubble level to confirm proper tilt angle before fully securing the bracket to ensure correct condensate drainage away from the window. Follow local building codes and the AC manufacturer guidelines for window support and load-bearing requirements.
