Double grids, offering a combination of mesh support values, are used primarily in metallurgical applications for supporting thin metal foils. Two grids are joined by a thin 'hinge', allowing one grid to be folded on top of the other, trapping the specimen between them. The grids have a curved securing tab which folds to the curvature of the doubled grid.
