Can I get the dimensions of the anvil plate used on MultiTest and OmniTest stands ?

Answer: 

You can download the technical drawings for the anvil plates used on Mecmesin's single-column and twin-column test frames here. They contain both the overall dimensions and also the details of the fixing threads available to attach grips and fixtures.

Drawing 408-477 covers the anvil plate used on single-column MultiTest and OmniTest stands having rated capacities between 0.5 - 7.5kN.
Drawing 408-459 covers the anvil plate used on twin-column MultiTest and OmniTest stands having rated capacities between 10 - 50kN.
Drawing 428-097 covers the base section used on twin-column MultiTest and OmniTest stands having rated capacity of 50kN.
Drawing 428-031 covers the base section used on twin-column MultiTest and OmniTest stands having rated capacity of 10 - 25kN produced from 2020 onwards**
Drawing 428-DW covers the base section used on twin-column MultiTest and OmniTest stands having rated capacity of 10 - 25kN produced before 2020**

** The first 2 digits of the serial number of the test stand provides the year of manufacture. Eg. 19-xxxx-xx  was manufactured in 2019.
