For anyone setting up office partitions or sneeze guards, these aluminum support clamps are seriously essential hardware! Made from strong aluminum alloy with a corrosion-resistant, rust-proof finish that won't fade over time. The heavy-duty construction provides steady support for your acrylic dividers, plexiglass shields, or privacy panels. The adjustable design fits desk, counter, or table thicknesses ranging from 0.67 inches to 2 inches (1.7cm to 5.1cm), making them versatile for various furniture types. Each clamp measures 1.65x1.3x2.36 inches with a C-shaped base of 2.05x2.05x3.62 inches - substantial enough for stability but compact enough to be unobtrusive. The package includes a set of 2 clamps with all necessary hardware: C-clamps, clamp bases, screws in two lengths (20mm and 25mm), a screwdriver, and non-slip rubber mats to protect your furniture surface. The two different screw sizes accommodate acrylic panels ranging from 0.079 inches to 0.59 inches thick (2mm to 15mm). The bead blasted finish gives them a clean, professional look that works with any office or commercial decor. Installation is straightforward with the included screwdriver, and the design ensures your partitions stay securely in place. For longer plexiglass shields, using 4 supports is recommended for maximum stability. These clamps are perfect for creating COVID-safe workstations, privacy dividers, or any situation where you need to mount clear shields on desks or counters. They provide that professional, finished look while ensuring your partitions remain stable and secure through daily use.
