The FinCap is design for a nominal 1.5” (1.5”ID/1.9”OD or 40mm screed pipe. Black iron or standard galvanized pipe is readily available in this dimension and is commonly used for a screed pipe.
A 1.25”ID or 2”OD screed pipe may be used however, the string line or laser needs to be adjusted to accommodate the different pipe size when using the MAKO Driver for setup. We recommend always testing the system when using a different pipe size.
