Summit 2 Rooftop AC Extension Kit

This extension kit is designed for the OutEquipPro Summit 2 rooftop air conditioner when installed on RV, van, or trailer roofs thicker than 3.5 inches and up to 8.7 inches.

The standard Summit 2 fits roof thicknesses of 1.5–3.5 inches. For thicker roofs, the indoor panel and outdoor unit cannot fully connect without an extension. This kit bridges the gap and ensures a proper, sealed air duct connection between the indoor and outdoor units.

Features:

ABS vehicle-grade air duct spacer – factory molded to precisely match the AC air duct.

Insulation foam wrap – surrounds the spacer for improved thermal insulation and efficiency.

Lightweight construction – air duct spacer weighs only 12.6 oz (356 g), easy to handle and install without adding stress to your roof.

Stainless steel threaded rods and screws – durable, corrosion-resistant, and sized specifically for thicker roofs.

What’s included:

Air duct extension spacer x 1

M8 threaded rods x 4

M4 screws x 4

With this kit, you’ll have everything needed to achieve a safe, airtight, and professional-grade installation of your Summit 2 unit on thicker roof builds.
