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

Heavy Duty Universal AC Support Bracket by GNILLKO is designed for 12,000 to 24,000 BTU A/C units, supporting up to 165 lbs. Made of high-density material, it features a solid epoxy-coated thick steel plate with a matte surface to prevent the A/C unit from dropping out of the window.

The window air conditioner bracket requires specific window requirements to ensure proper installation. The window sill thickness cannot exceed 15 inches, must be a minimum of 1 1/2 inches deep for placing the base, and must be able to accept 3-inch long screws. The sliding window lip or window stool cannot exceed 2 1/2 inches. Please note that it cannot be used with slide casement or casement windows.

The product includes a block and spacer system with adjustable spacer to keep the balance of the brace on the window sill. Rubber mounts are designed to fit the siding wall securely without causing damage to the outside wall. An exclusive built-in bubble spirit level helps correct mounting slope position for accurate installation.

The universal design of the AC support bracket fits most window A/C units on the market and is suitable for solid window sills, brick, cement, and solid wood. The adjustable leg allows for flexible adjustment of the support arm length from 10 3/4'' to 15 3/8'', accommodating various exterior wall types and alleviating weight stress on window frames.

With a wall thickness range of 4'' to 15'', the window air conditioner bracket also includes a built-in bubble spirit level for precise mounting angle adjustments. Easy installation is ensured with the necessary hardware and instruction sheet included in the package, allowing for indoor installation by drilling into the window sill without the need to drill holes in the exterior wall or siding.

Constructed from durable, high-grade steel coated to prevent rust and rot, the air conditioner support bracket transfers stress and weight from the window sill and sash to the support and window frame for safety and stability. Upgrade your air conditioning unit with the reliable and sturdy Universal AC Support Bracket from GNILLKO.
