Aluminum Dual Pipe Support for Aluminum Beams

The Aluminum Dual Pipe Support for Aluminum Beams works with the Coastal Series overhead boat lifts. Slides on the aluminum structural beams. Fits 6 in. Web x 4 in. flange beam. The two welded sleeves include 1/4 in. grease fittings at the bottom of the sleeves. Allows for easier greasing.

The sleeves prevent the pipe from walking up the side. Guarantees a truer alignment. Allows plenty of room for an optional cable winder. More than 19 inches between each sleeve. Includes stainless steel fasteners.

Dual pipe supports, with or without hoist hanger, is best used in a center mount configuration. A 4,000 lb. maximum rating per hoist hanger when used correctly in center mounting. Side mounting greatly reducts the dual pipe support and hoist hanger capacity. A 1,000 lb. maximum rating when used correctly for side mounting. See the attached guide for more information and limitations.

Center-mount pipe supports are only recommended for center mount or twin mount installations. It is not recommended to use pipe support on a side mount installation. Never attempt to straight-line lift any more than 4000 lbs on a side mount overhead lift or straight line more than 6000 lbs on center or twin mount lifts. Only use the full length of the pipe to connect both pipe supports. 

Do not attempt to use two short pieces of the drive pipe. If designing or engineering your overhead lift, you must download and read the BH-USA overhead boat lift guide that can be found on this page. Also available in the tech guide section. BH-USA makes available complete engineered and rated lifts and highly encourages choosing this option over designing and engineering a boat lift on your own. 

The above ratings of the dual pipe supports are only valid if installing or using the pipe supports with the BH-USA overhead boat lift guide. The Side Mount and Twin Mount ratings are based on straight line pull. Rating is based on per pipe support and not per boat lift. When considering the weight of your boat, you must use full wet weight plus the weight of the boat cradle. (wet weight + boat cradle weight = total lifting weight)

BH-USA engineers and manufactures factory-rated complete boat lifts. We highly recommend purchasing one of these boat lifts instead of building your own. If you, or your installer, buys parts and pieces to engineer your custom boat lift, it will no longer be considered a Boat Hoist USA engineered boat lift.
