The FinCaps supports 1-1/2″ (40 mm) Pipe (1.5″ ID/1.9″ OD). A 1-1/4” or 2” pipe may also be used. Minimum height using a 1-1/2” ID pipe from the bottom of the FinCap chair to the finished elevation of concrete is 3-5/8” (92 mm).
The “fins” inside the screed chair hugs rebar, threaded rod, conduit, metal stakes, or PVC pipe from 3/8" (10mm) to 5/8" (16mm.) The FinCap holds up to 1,000 lbs making it the most versatile screed support available.
Use with the MAKO Driver for accurate elevation control of concrete slabs and structural elements for a fast and easy setup.
The stay-in-place forms are designed to stay in the slab and are corrosion resistant, even in extreme environments. They are non-metal and non-conductive which makes the chairs perfect for bridge decks, waterways, and power plants.
