Building a glass railing or fence? These DIICCYO clamps are your go-to solution for a clean, modern look without drilling holes in your glass! They're super sturdy, made from corrosion-resistant Stainless Steel 304 with a sleek matte black finish that looks great indoors or out. The 180-degree design lets you join two glass panels seamlessly edge-to-edge, perfect for creating corners on balconies, stair railings, or around your swimming pool. They're designed for glass that's between 3/8\ and 1/2\ thick (that's 10mm to 12mm). Installation is a breeze - you just align your glass panels, fit the clamp around the edges, and tighten the screws. No need for messy drilling or special tools. Each clamp measures about 3.46\ x 0.98\. The pack comes with 4 clamps, which is usually enough for a corner or a small section. They're super versatile for home offices, garden enclosures, shower screens, or any place you want that open, airy feel with glass. Durable, easy to install, and they give a really professional finish. Just make sure your glass is the right thickness, and you're good to go!
