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. 
 
Base Plate 4.5 
The Base Plate 4.5 is used with the FinStand to expand the uses of the system to vapor barriers, concrete overlay, rock or sand plus any other type of substructure. The FinStand snaps and securely locks into the Base Plate. The assembly can be secured into place either by using screws, nails, construction glue or other adhesives.
 
The Base Plate is made of impact resistant material and is virtually unbreakable. The bottom of the Base Plate is textured to easily grip adhesives for extra staying power. It also provides a suitable surface for patching when used in tilt-up applications. 
 
The stay-in-place form can be easily setup by inserting a 1/2″ (13 mm) rod between the bottom of the FinStand and Base Plate 4.5.
