A-08 is a 509.8g three-hole steel plate for armrest posts. This steel plate plays a key role in the chair armrest system. It is made of high-quality steel, strong, and able to withstand considerable pressure and weight. The layout of the three holes is carefully designed to facilitate precise docking with the armrest posts, and the pre-embedded installation makes it closely connected to the building structure. A-08 can provide stable foundation support to ensure that the armrest posts are installed firmly and safely and is a reliable accessory choice in the handrail installation project.
