ändlås

ändlås is a generic term used in Swedish technical language to describe a locking device designed to secure the end of a component such as a rod, tube, or rail against axial or rotational movement. The term does not correspond to one universal standard or design; the exact form and mechanism vary with the application.

Etymology and scope: The word combines the Swedish words for end (änd) and lock (lås). In practice, ändlås refers to end-based locking solutions used to retain or locate components at the terminal part of a member.

Construction and function: An ändlås typically consists of a body that fits on or into the end of a component and a locking element that holds the end in place. Locking elements can include set screws, clamping collars, wedges, or threaded end caps. Depending on the design, the lock may prevent axial displacement, rotation, or both. Some implementations rely on an interference or press fit, while others use grooves, keys, or clamping features to achieve retention.

Applications: It is used to retain end caps on tubes or profiles, locate parts on shafts, or secure hollow sections in furniture, machinery, HVAC systems, marine equipment, and other industrial contexts. End-locks are chosen for removability, load requirements, and environmental conditions.

Materials and maintenance: End-lock components are usually metal (such as steel or aluminum) but can be plastic for lighter-duty use. Corrosion resistance and surface finish depend on the operating environment. Regular inspection focuses on wear, loosening of locking elements, and corrosion.
