AGG2764N, F4 Finder Grids Nickel 3.05mm (Tube of 100)

A rectangular mesh grid with an effective 200/300 mesh, giving greater support than the other finder grids. 
Each grid rectangle is asymmetrical, with a different outline in each corner allowing the orientation to be observed at light microscope level. Indexing enables the position to be identified with reference to letters A - O along the horizontal axis, and the numbers 1 - 15 along the vertical axis. 
Gold grids are made to order only. 
Gold grids are supplied in tubes of 50.
