FinCap product data sheet
 
The patented, non-metallic MAKO FinCap fits mounting structures from 3/8″ (10 mm) to 5/8″ (16 mm) making it the most versatile screed support chair available. It will not bounce off your mounting structure because the “fins” inside hug the mounting structure.

The FinCap supports a nominal 1-1/2″ (40 mm) – schedule 40 or higher – galvanized pipe (1.5″ ID/1.9″ OD).  The FinCaps are virtually indestructible and have a 100% no breakage money back guarantee that they will not break, snap, or crush under a screed during normal placement conditions.
