Lunmar I-Beam Mount Cradle Kit (4,500#, 6,000#, 7,500#, 10,000#,12,500# ,15,000#,20,000#)

The Lunmar I-Beam Clamp (IBC) cradle boat lifts are designed to clamp to the flange of an existing pair of I-beams located over the lift points of the boat. The I-beams in these I-beam mount kits can run across the boat or in line with the boat. The gearbox mount, sealed bearings, and offset hangers all clamp to bottom flange of beam and require no drilling. This is one of the easiest boatlifts to install and is available at great boat lift prices.

Please specify flange width of I-beam when ordering (how wide is the beam?). For example, most 8" beams have either a 4" or 5.25" flange, most 6" beams have a 3.3" or 4" flange.
