The Heart of Precision Elevation Control HOW TO USE: Draw string line to finished elevation. Repeatable. Accurate. Fast. Eliminates elevation guesswork. |
Its patented internal "fins" in each MAKO screed chair hug the mounting structure so the chair will not bounce off rebar or rod during concrete placement.
Using MAKO Screed chairs with the FinStand®, CoilStand®, and Base Plate assemblies, contractors can create fully adjustable support systems that sit securely on the vapor barrier while supporting screed rails, lumber screeds, anchor bolts, embeds, threaded rods, and other structural elements. The Base Plate distributes load across the surface, preventing punctures while maintaining precise elevation control during concrete placement.
SPECIFICATIONS:
Packaging: 100 pieces per bag - Approximately 3,000 sq ft coverage per bag
Spacing: Typically every 3-4 feet (1 meter) depending on screed weight, pour span and subgrade. Always test conditions prior to placement.
Mounting Structure Compatibility: 1/2" 13 thread for the FinStand, 1/2" x 6 thread for the CoilStand
Material: Impact-resistant medical grade polypropylene
Minimum Slab Thickness: Varies by chair and mounting structure
