What desk thickness works with a clamp-mount monitor arm?

Standard C-clamp monitor arms accommodate desk thicknesses from 0.4" (thin glass) to 3.5" (thick solid wood or built-up laminate). Verify the maximum clamp jaw opening in the arm specs — most commercial desks are 1"–1.5" thick. For unusually thick desk edges (4"+), specify a grommet mount or a through-bolt mount. At OfficeFurniture2go.com, all clamp-mount arms list maximum desk thickness — call 1-800-460-0858 if you have a non-standard desk edge or need a mounting solution for thick surfaces.
