This versatility ensures a perfect fit for your window, regardless of its dimensions.

Crafted from durable, high-grade steel, the air conditioner support bracket is coated to prevent rust and rot, and features a matte finish to prevent the air conditioner from falling out of the window. This robust construction guarantees long-lasting support for window units weighing up to 220 pounds.

Installing the GNILLKO Air Conditioner Support Bracket is a straightforward process that can be completed from inside your home. No tools, drilling, ladders, or hardware are required to secure the bracket in the window frame, ensuring that there is no damage to the exterior walls or window sills. Detailed installation instructions are included in the package to guide you through the process.

The upgraded support structure, featuring support legs and extension beams, provides extra support both inside and outside the window. The integrated rubberized feet add stability, ensuring a secure and level placement of your air conditioner.

The adjustable support leg design allows for a seamless fit between the air conditioner and the window sill, eliminating any gaps. Furthermore, the included bubble spirit level with a magnetic bottom attaches smoothly to the bracket during installation, enabling you to easily verify that the bracket has been leveled. This feature allows you to find the perfect angle for your air conditioning unit, ensuring optimal performance and efficiency.
