Marshalltown Concrete Screed Rail Support System Chairs w/ Drive Tool

Spin Screed® Support System Chairs are designed to work with a Screed Rail to section off large pours so you can easily screed form-to-rail or rail-to-rail for flatter finished surfaces. These Chairs come in two styles: Universal Bypass and Heavy-Duty. 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. Both options reduce your required fill by 85% compared to other pipe-style screed rail systems. Simply push, pull, and shake a Bull Float over the surface to create a strong, aggregate interlock. Drive Tools are included with each purchase of either a pack of 100 or 500 Chairs. All our Support System Chairs are Made in the USA with Global Materials.
