Spartite Mast Collar Covers - 102 Cubic Inches

Spartite provides a precise solution for bridging the spaces between the mast and partners on your boat. This two-part polymer system is pre-measured and simple to pour into the cavities, ensuring a snug fit. Each Spartite kit is complete with everything you need, including easy-to-follow instructions, modeling clay, foam support strips, a pouring cup, stirring sticks, and plastic gloves. Calculating the quantity of Spartite is straightforward: Simply measure the square inch area of the mast, subtract it from the square inch area of the partner opening, multiply by the desired depth (at least 2 inches), and add 1/4 inch. Should you need more, additional Spartite can be mixed and added at any time.
