Part # : SPNYSP - Support System Chairs w/ Drive Tool

Improve concrete flatness, increase screeding accuracy, and make setup easier with the MARSHALLTOWN Spin Screed® Support System Chairs with Drive Tool. Designed to work with the MARSHALLTOWN Spin Screed® system, these support chairs help maintain consistent screed height and grade control, allowing contractors to achieve more uniform concrete surfaces with less adjustment and rework.

The Spin Screed® Support System helps remove common challenges associated with long concrete pours, including maintaining proper elevation, controlling screed movement, and achieving consistent slab thickness. The chairs provide stable support points for the screed rails, helping crews establish a reliable reference plane before placing concrete. This improves workflow efficiency and helps operators produce flatter, more accurate slabs with reduced physical strain.

The yellow Universal Bypass Chairs have a double profile (a ¼” and ½” gap) that can fit either a single rail or two rails side-by-side on the same chair, thus bypassing each other and allowing the Screed to pass seamlessly from one Screed Bar to the next. Our green Heavy Duty Chairs have a stronger, single rail (¼” gap) profile that can support heavier screeds.

The included drive tool makes installation faster and easier by allowing crews to quickly secure the support chairs into the concrete base. By simplifying setup, contractors can spend less time preparing the screed system and more time focused on efficient concrete placement. The durable construction is designed for professional jobsites and repeated use across a variety of flatwork applications.

Compatible with MARSHALLTOWN Spin Screed® Pipes, Power Heads, Screed Rails, and other system components, the Support System Chairs with Drive Tool help create a complete concrete leveling solution that improves productivity from setup through final finish.
