What Is the FinStand® and CoilStand®?
MAKO FinStand and CoilStand assemblies combine stay-in-place screed chairs with threaded rod adjustment to provide precise, vertically adjustable elevation control for slab-on-grade and elevated slab construction. They are designed to hold the FinCap® and all JAWS® screed chairs when setting grade for elevated slabs on wood or metal decks.
