This PVC ferrule (12 mm size) is designed to slip neatly onto/insert into the end of a 12 mm tube or square section (depending on design). It serves as a furniture leg cap or leg tip, helping to protect floors from scratches, reduce noise when moving furniture, and give a clean, finished appearance to the leg. Its plastic (PVC) construction offers good durability, resistance to moisture, and an easy‑to‑fit solution for chairs, tables, shelving or metal tubing ends.
