JAWS RailFin   JAWS RailFin Screed Chairs are designed for to fit a 1/4” flat rolled steel rail. All the JAWS chairs fit rebar or rods from 3/8″ (10mm) to 5/8″ (16 mm). The “fins” inside the barrel hug the rebar or stake so it will not bounce off during placement.

FinStand   The FinStand is made of impact resistant material and is virtually unbreakable. The FinStand supports with a 1/2″ all-thread. The stand can be adjusted 1.75″ (45 mm) using a nut and washer to accommodate any variation in the deck. See the chart below for rod length needed for the desired floor depth.
