Aluminum PipeFor Sailors, the "Tower in a Box" Arch from Atlantic Towers is designed to mount to the deck, transom, hull sides or a combination. The approximate 30 degree angle, clears most existing biminis, back stays, and pushpits. Mounting hardware (feet) is shipped loose and epoxied and screwed into the legs at the time of installation. The legs may be trimmed for the best overall height, and at unequal lengths to facilitate installation. There is a choice of mounting hardware, with 3.5" or 2" diameter bases. Our proprietary pin and pad mounting system accommodates any angled mounting surface.
Telescoping design allows adjustment to fit many different transoms and applications.

High Strength welded frame of schedule 40 marine grade aluminum pipe nearly 2" in diameter, with secondary reinforcement of nearly 1 3/8" in diameter finished in durable salt resistant bright clear anodizing

The Arch has the appearance and strength of a custom welded unit when installed on your boat. It weighs less than 100 pounds, and is strong enough to support the weight of two persons for the installation of equipment.

Every Arch includes a large (approximately 12" x 12") radar plate, plus four 4" wide mounting plates which will accommodate up to six additional antennas. Radar cables, antenna cables and other wiring may be concealed inside the frame The Arch is mounted to your boat in four locations with our proprietary "Pin & Pad" mounting hardware. These fittings have nylon bushings which help isolate any vibration in the Arch from the fiberglass surface of your boat. The "Pin & Pad" fittings also allow mounting to any angled surface, and easy dismounting of the arch (just remove the four 3/8" bolts) for storage or transport. You have a choice of 3-1/2" 5 bolt bases click here for details, or 2" diameter 2 bolt bases click here (new page, Kit #6 detail) Cupped feet, to allow direct pass thru of electrical cables are available at additional cost.


Everything is included for a complete installation on most boats, even backing plates along with instructions and a video detailing all the steps of the installation.
