- Height adapts to 1 to 4 cm differences, enabling a smooth tilt transition between floors in adjacent rooms. - Durable aluminum alloy construction offers excellent water and moisture resistance, making it suitable for humid environments such as kitchens and bathrooms; it is scratch- and wear-resistant for long-lasting performance. - Available in multiple colors and sizes to match different interior styles and threshold widths. - Easy installation with glue; no special tools required. - Key benefits: reduces trip hazards, protects floor edges, and seals gaps for a cleaner transition. - Use scenarios: 1) Bridging a threshold between a tiled kitchen and a wooden or laminate living area. 2) Installing at doorways to bathrooms or other moisture-prone spaces. 3) Connecting carpeted rooms to hard floors where height differences occur.
