BR-GK003 Double Sided Glass Door Knob, 304 Stainless Steel Grooved Tapered Frameless Shower Door Handle with Mirror Polish & Satin Brushed Finish

Manufactured from high-purity 304 stainless steel, the BR-GK003 glass door knob delivers exceptional structural strength, outstanding corrosion resistance and long-term durability in humid bathroom and shower environments. Different from the smooth cylindrical profile of BR-GK001 and BR-GK002, this model features an elegant tapered waist silhouette with multiple concentric ring grooves, adding rich layered texture and a subtle luxurious touch that elevates the overall look of glass door systems. It offers two premium surface finish options: a highly reflective mirror polish that enhances the grooved details with crisp light reflections, and a matte satin brushed finish that softens the lines, resists fingerprints and maintains a clean contemporary appearance with minimal upkeep. Designed for through-glass installation on frameless toughened glass panels, this double-sided knob fits securely without complex frame modifications. It is fitted with precision silicone gaskets on both mounting sides, which evenly distribute clamping force, eliminate direct metal-to-glass contact, and effectively prevent glass urface 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 decorative grooved glass door knob is perfect for high-end frameless shower rooms, bathroom glass partition walls, boutique interior glass doors and small glass entry doors, combining reliable functionality with a distinctive refined aesthetic for both residential and commercial spaces. Bulk wholesale orders and OEM customization services are fully supported.
