| Spreaders |
| Spreaders are used on most Rigs to improve Mast support by increasing
Upper (and Intermediate) Shroud angles. Spreaders are specific to particular Spreader Bases
(or Spreader Bars), which, in turn are specific to individual Mast Sections. A variety of extruded
Aluminum Spreader shapes are listed below.
For Spreader replacement applications, it is necessary to determine the Outside diameter (for Round Spreaders), or the specific Spreader Section (for Airfoil Spreaders). Rig-Rite stocks a large selection of replacement Spreaders, most are listed below. If you require
Spreaders not listed here, please forward details on your Spreader, including a tracing
of your Spreader
Section with maximum Outside dimensions, wall thickness, and boat model and year.

| Airfoil Spreader Sections |
| Extruded Aluminum Airfoil Spreader Sections are produced by different
Manufacturers and are usually quite specific to the bases or inboard attachments provided by those
Manufacturers. For Airfoil Spreader replacement applications (and parts), it is necessary to determine the specific Spreader Section you have. If you know the Manufacturer of your Spars this process can be simplified. If not, look through the Manufacturers listed below to see if you can find your Spreader Section.
