Sparcraft S Mast Sections


Sparcraft S Mast Sections are designed as approximate replacements for some discontinued Sections.
Please note that Sparcraft has recently relabeled some of its' existing Sections with the S- prefix. For example, what for many years was called an FM-305 they now refer to as an S-305, what was called an IM-180 they now refer to as an S-180, though in all these cases nothing physical has changed. For simplicity, convenience, and as historical convention, we only refer to new Sections with the S- prefix as S-Sections. Even the S-622 & S-830 were originally (for a short time), referred to as I-622 & I-830, but, as these are New shapes falling into no previous categories, we use the S- prefix. All other renamed Sections will be found under their Original designation, See FM Mast Sections, and IM Mast Sections.

Though Sparcraft uses a number of common components in their Spar Assemblies, many Mast Parts are specific to a particular Mast Section. For these parts you must determine which Mast Section you have by measuring its' maximum Outside Dimensions. Click on individual Mast Sections, below, to see hardware commonly used with those Sections.

For common replacement Mast Parts, See Sparcraft Mast Components, below.
For complete Mast Assemblies, contact us with details.
