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.

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.
