BR-GK004 Double Sided Glass Door Knob, 304 Stainless Steel Wide Flange Dual-Ring Frameless Shower Door Handle with Mirror Polish & Satin Brushed Finish

Manufactured from high-purity 304 stainless steel, the BR-GK004 glass door knob delivers exceptional structural strength, outstanding corrosion resistance and long-term durability in consistently humid bathroom and shower environments. In shape distinction from the sleek straight stepped profile of BR-GK001 and BR-GK002, and the fine multi-grooved tapered design of BR-GK003, this model features prominent wide flange rims at both ends paired with a dual-ring recessed waist, creating a fuller, more substantial silhouette with deep defined contours that bring a classic, substantial premium feel to glass door systems. It offers two premium surface finish options: a highly reflective mirror polish that accentuates the three-dimensional contours and wide rim details with crisp light reflections, and a matte satin brushed finish that softens the lines, resists fingerprints and maintains a clean understated appearance with minimal upkeep. Designed for through-glass installation on frameless toughened glass panels, this double-sided knob mounts securely without complex frame modifications. It is fitted with precision silicone gaskets on both sides, which evenly distribute clamping force, eliminate direct metal-to-glass contact, and effectively prevent glass surface scratches, chipping and stress cracking during installation and daily operation. Its solid one-piece stainless steel construction ensures a firm, wobble-free grip and long-term stability without loosening over time. Fully waterproof and rust-resistant, it is purpose-built for wet and humid bathroom environments. Installation is straightforward with standard included mounting hardware, suitable for both new construction projects and glass door renovation upgrades. This wide-flange glass door knob is perfectly suited for frameless shower rooms, bathroom glass partition walls, residential interior glass doors and small glass entry doors, combining reliable daily functionality with a distinctive robust classic aesthetic for both residential and commercial spaces.
