This suction cup retractable towel bar is made of stainless steel, with a length adjustment range of 17-29 in. fitting wall spaces of different widths. It adopts a snap design paired with thickened silicone suction cups, which provide stronger adsorption force and prevent falling off during daily use. With a rated load-bearing capacity of up to 15 lbs. it can stably hang multiple towels. Installation requires no drilling, leaving no marks on the wall. Its surface has been treated to have anti-aging properties, maintaining a clean appearance even after long-term use. During use, you can freely disassemble the bar or adjust its length with smooth and easy operation. It should be noted that the product is not suitable for rough or painted surfaces, only for smooth surfaces such as glass and marble. If used on slightly rough surfaces like wooden doors or frosted walls, you can use the adhesive disc included in the package to smooth the surface before installation.
