Using this 450mm LED grab rail is easy. First, decide where you want to install it - it can go horizontally, vertically, or diagonally in bathrooms, toilets, or other areas. Then, use the screws to fix it to the wall and cover the flanges with the provided cover plates. When the light gets low, the sound - activated LED lights will turn on to guide you. Remember to buy two AA batteries to power the lights. As for maintenance, simply wipe the rail with a soft cloth regularly. Since it's made of grade 304 stainless steel, it's quite durable, but avoid using abrasive cleaners that could scratch the finish. And keep in mind that it can support up to 250 kg, so don't exceed this weight limit.
