Description
Square tube insert 16×16 mm, black

The black Square tube insert 16×16 mm is a practical finishing component for closing the ends of square tubes and profiles. It fits into the open end of the profile, covering the edge and protecting the interior from dirt.
The insert consists of a flat head that covers the edge of the profile and a ribbed section. The ribs press against the walls of the profile and hold the insert in place. The insert is designed for profiles with wall thicknesses of 1.0–2.0 mm, making it suitable for profiles with different wall thicknesses.
Applications
- closing the ends of 16×16 mm square steel and aluminium profiles
- finishing support structures, frames, stands and equipment components
- neatly covering the cut edge of a profile
- reducing the ingress of dirt into the profile

The insert is made of polyethylene, a plastic commonly used for protective and finishing components. Its black colour complements dark profiles and structures, while the smooth head provides a neat finish.
The product is sold individually, making it easy to order the exact number of inserts needed for a specific job. Its low weight and compact dimensions allow it to be shipped as a small parcel.
