päätykappale

Päätykappale, literally translating to “end piece,” is a component designed to terminate, cap, or close the end of an object such as a profile, tube, rail, or enclosure. The term is used in Finnish technical and manufacturing contexts to denote the final part that provides a finished appearance, protects the end, or connects to adjoining components. Päätykappale is a generic descriptor that covers a variety of designs and applications.

In woodworking and furniture making, päätykappale refers to end caps or end pieces used to finish the ends of rails, mouldings, frames, or countertops. They help prevent splintering, conceal joints, and create a clean edge. Materials commonly used include wood, plastic, and metal, with finishes tailored to match or contrast the piece.

In piping, tubing, and metalwork, end caps seal the ends of pipes or tubes to prevent ingress or leakage and to provide a neat termination. End caps can be threaded, slip-on, or welded, and are produced in materials such as steel, stainless steel, aluminum, and plastic.

In construction and hardware, end caps for profiles or extrusion systems terminate the length of a rail or frame, often for safety and aesthetic reasons. These end pieces are available in various sizes, shapes, and finishes, including powder coatings and anodized surfaces.

Selection and installation considerations include correct size and profile match, mounting method, material compatibility with surrounding parts, and the intended environment (indoor or outdoor). Properly chosen päätykappale contribute to durability, safety, and a polished appearance in assemblies.
