GNILLKO Window Air Conditioner Support Bracket, Universal for 12,000 to 24,000 BTU AC Units

The GNILLKO Window Air Conditioner Support Bracket is a heavy-duty universal AC support designed for 12,000 to 24,000 BTU units, capable of holding up to 165 lbs. This bracket is engineered to provide a secure and stable mounting solution for your window air conditioner.

The window requirements for this bracket are as follows: the window sill thickness cannot exceed 15 inches, the sill must have a minimum depth of 1 1/2 inches to accommodate the base, and the sill must be able to accept 3-inch-long screws. Additionally, the sliding window lip or window stool cannot exceed 2 1/2 inches, and the bracket cannot be used with slide casement or casement windows.

Constructed with a solid epoxy-coated thick steel plate and a matte surface, the GNILLKO bracket is designed to prevent the air conditioner from falling out of the window. The spacer can be adjusted on the block according to the inclination of the window sill, ensuring the brace remains balanced and the bracket is properly installed.

The full-rubber mounts on this bracket are designed to provide a secure and stable fit, conforming to the siding wall without causing any damage to the exterior. The exclusive built-in bubble level ensures accurate mounting slope positioning, allowing for easy and precise installation.

This universal design air conditioner support bracket is compatible with most window AC units on the market, suitable for various window sill materials such as solid, brick, cement, and solid wood. It can also adapt to tilting installation surfaces, providing a versatile solution.

The innovative leg extender design allows for flexible adjustment of the support arm length, from 10 3/4 inches to 15 3/8 inches, accommodating a wide range of exterior wall thicknesses, from 4 inches to 15 inches. This feature helps alleviate weight stress on the window frames, ensuring a secure and reliable installation.

The package includes all necessary hardware and an instruction sheet, allowing for easy indoor installation by simply drilling into the window sill, without the need to drill holes in the exterior wall or siding. This eliminates the hassle and potential damage associated with outdoor installation.

The GNILLKO Window Air Conditioner Support Bracket is built to last, with a durable, high-grade steel construction coated to prevent rust and rot. The matte finish further ensures the air conditioner remains securely in place, as the bracket transfers the stress and weight from the window sill and sash to the support and window frame, providing enhanced safety and stability.
