NOTES Total vertical space is the distance from the top surface of the base plate to the bottom surface of the crosshead.

The standard base plate features four hole patterns for mounting fixtures; M4, M6, M10 and M12. An optional imperial base plate features #10-32, 5/16-18, 1/4-28, and 1/2-20. The base plate can be easily positioned to ensure correct sample alignment.

Two mounting blocks are available for attaching a Starrett force gage or the BLC Load Cell. The blocks attach easily and securely to the crosshead and ensure correct center line alignment.

A stainless steel clevis set is included with the FMM test frame base. The clevis will accept 15.9mm diameter test fixtures. The clevis set includes the clevis, locking rings, grip pin and a spanner wrench.
