To use this grab bar anchor, first measure and mark the position on the 1/2 - inch thick toilet compartment panel where you want to install the grab bar. Then, drill holes according to the markings. Insert the anchor into the hole firmly. Next, attach the grab bar flange to the anchor. Make sure everything is tightened properly. When using, avoid applying excessive force suddenly on the grab bar. For maintenance, regularly check if the anchor and the grab bar are loose. If they are, tighten them up. Keep the area around the anchor clean to prevent dirt from affecting its performance.
