A-10 is a 461.8g iron plate handrail accessory column base. The 4-hole steel plate designed for round tube handrails occupies an important position in the handrail system. The steel plate is made of high-quality iron plate material and has good strength and durability. The 4 holes are designed to better fit the round tube handrail column, allowing the column to be firmly installed on it. In practical applications, whether it is a stair handrail in a family residence or a corridor handrail in a commercial building, the A-10 column base can provide a stable bottom support for the handrail, ensuring the safety and reliability of the handrail structure.
