The COAST H40 Aluminium Roof Mount H-Frame is designed to provide additional structural support when installing a roof-mounted air conditioner on caravans, motorhomes, and gooseneck trailers. By spanning across the roof structure, the H-frame helps distribute the air conditioner’s weight evenly, reducing roof flex and improving long-term durability.

Manufactured from heavy-duty aluminium RHS (50 mm × 25 mm), this H-frame is supplied flat and may be trimmed to suit the roof width of your vehicle. It is specifically designed to suit 400 mm × 400 mm roof openings, making it compatible with most European-style roof air conditioners.
