Window Air Conditioner Support Bracket, Up to 165 lbs, Universal for 12,000 to 24,000 BTU AC Units

Introducing the GNILLKO Window Air Conditioner Support, a heavy-duty, universal AC support bracket designed to hold A/C units weighing up to 165 lbs, ranging from 12,000 to 24,000 BTU. This support bracket is constructed from high-density, solid epoxy-coated thick steel plate with a matte surface to prevent the A/C from dropping out of the window.

In order to ensure a proper fit, the window sill must be a minimum of 1 1/2 inches deep for placing the base, and the window sill thickness cannot exceed 15 inches. Additionally, the window sill must be able to accept 3-inch long screws, and the sliding window lip or window stool cannot exceed 2 1/2 inches. It is important to note that the support bracket cannot be used with slide casement or casement windows.

The GNILLKO Window Air Conditioner Support features an adjustable spacer that can be altered on the block according to the inclination of the window sill to maintain balance. Full-rubber mounts are designed to fit the siding wall and make the bracket stable and firm, without causing any damage to the outside wall. The support bracket also comes with an exclusive built-in bubble level to ensure correct mounting slope position.

This universal design is suitable for solid window sills, brick, cement, and solid wood, and is equipped with an innovative leg extender design that allows for flexible adjustment of the support arm length. It can accommodate wall thickness from 4 inches to 15 inches and comes with a built-in bubble spirit level for precise mounting angle adjustments.

Installing the GNILLKO Window Air Conditioner Support is a breeze, with all necessary hardware and an instruction sheet included in the package. All installation can be completed indoors by simply drilling into the window sill, eliminating the need to drill holes in the exterior wall or siding. Made of durable, high-grade steel coated to prevent rust and rot, this support bracket transfers the stress and weight from the window sill and sash to the support and window frame for added safety and security. Experience peace of mind knowing that your A/C unit is securely supported with the GNILLKO Window Air Conditioner Support.
