Complete Pedestal Assembly with Base & Head

 

 

Base
The piece that's attached to the sub-floor by a mastic or mechanical fastener.  The base's height and pedestal head determine the finished floor height.

 

Flat Head
Inserts into the base and includes holes to fasten panels and stringers. There's usually a leveling to allow fine adjustments to the desired finish floor height.

 

Stringer
A metal channel or square tube that's attached to the pedestal head that forms a grid and provides lateral stability. May either be snapped into place or fastened from the top with a screw.  Stringer are available in 2’ and 4’  lengths allowing for standard (2' x 2'), (4' x 2') or (4' x 4') installations.

 

Rigid Grid System

Offering great lateral support,  this system is generally used where panels are gravity held on the understructure.
