SP4 Spreader Bases SP4 Spreaders are normally used with a variety of welded SS Spreader Bases which are formed to fit specific Mast Sections. On some masts they are used with special welded Inboard Spreader Ends (listed above) that fit between (2) aluminum Spreader Base Plates welded to the mast. Spreader Bases and Spreader Base Plates used with SP4 Spreaders are specific to individual Mast Sections and are listed under the Mast Sections that they attach to, See Kenyon Mast Sections.

SP4 Spreader Bars SP4 Spreaders frequently use a thru-mast Spreader Bar, especially in High Performance applications. Spreader Bars are machined to snugly fit the interior of the Spreader, and require that the inboard end of the Spreader be cut or filed to approximate the curve of the mast section. Spreader Bar is installed through a slot in the mast, the Spreaders fit over the Bar and are pinned straight through the Bar, holding the Bar and Spreaders in place. Spreader Bars are available in a variety of standard sweep-back angles, other angles are available on a special order basis. *SP4 Spreader Bars are listed below, and* under the Mast Sections they are commonly used with (Kenyon 4066 & larger Sections), and are also suitable for use with other similar-sized Mast Sections.**
