This adjustable and expandable straight shower curtain rod features a length that can be flexibly adjusted between 47 and 84 in. It fits different bathroom layouts and easily meets the installation needs of most bathtubs and shower areas. Crafted with a 304 stainless steel rod, solid brass brackets, and full-metal concealed screw flanges, it comes with a matte black finish. This not only ensures long-lasting rust resistance for durable use but also complements various bathroom decoration styles. With a 1 in. diameter rod, it is installed via screw drilling and fixing. Compared to tension-mounted shower rods, it offers stronger load-bearing capacity and never falls off, making it suitable for long-term use with all types of shower curtains or shower curtain lines. The installation process is simple: just mark the drilling position, drill a hole with a 1/4 in. drill bit, and fix the bracket. The package includes a full set of mounting hardware and an instruction manual. Additionally, it can be flexibly used in scenarios such as bathrooms, kitchens, bedrooms, and balconies as a shower curtain rod, window curtain rod, or closet hanging rod to meet diverse home needs. It is recommended to check if all parts in the package are complete before installation.
