Guard rails on 2-inch posts still use everyday glass, and the 816/2 lets them. Its curved back seats on 2-inch OD round tubing and the single-piece radius clamp takes 1/4 or 3/8-inch tempered glass, one part for either panel. Bolt it to the post, seat the glass in the gasketed jaw, and tighten; no drilling of the panel. It suits a stair guard, a balcony rail, or a partition on the larger post. Three finishes cover the likely rails. 304 stainless comes polished or satin for interior use. Clear-coated polished brass matches a brass railing and keeps its shine without a polishing routine. The same grip is offered for 1-inch and 1.5-inch posts and as a flat-surface version, so mixed runs can carry one hardware profile end to end. Ships from US inventory.
