Hot Dipped Galvanized Window Clamp for Door and Window Frame Fixing

This window clamp is specially designed for building curtain walls, door and window installations, and industrial frame fixing applications. Made of high-strength carbon steel through one-piece stamping, it features a uniform and dense hot-dip galvanized coating that provides excellent rust and corrosion resistance. It can withstand long-term exposure to outdoor humidity and temperature fluctuations without rusting or deforming, offering a much longer service life than ordinary galvanized fittings. The thickened and reinforced structure ensures strong load-bearing capacity. During installation, the bottom bolt tightly fits the profile, while the U-shaped slot on the top is compatible with various square tube profiles. It firmly secures the frame to prevent shaking, displacement, or even falling off caused by wind or external forces, providing reliable protection for building safety. Installation is quick and tool-free—simply insert the profile into the slot and tighten the bolt, allowing one person to complete the operation efficiently.
