Description
Rectangular tube insert 20×30 mm, anthracite

The Rectangular tube insert 20×30 mm in anthracite (RAL 7016) is used to close the open ends of rectangular hollow sections. Made of polyethylene, it covers the opening when pressed into the profile, giving the structure a neat, uniform finish.
The insert consists of a flat external flange and an internal section with ribs. The ribs enter the profile and press against its walls, allowing the insert to be fitted by simply pressing it in, without additional fixings. The flange covers the edge of the profile, while the core and ribs fill its interior.
Applications
- Closing the ends of 20×30 mm rectangular profiles in frames, bases and support structures
- Finishing areas where profile ends remain visible
- Covering the open end of a profile after cutting
- Matching the anthracite colour (RAL 7016) to dark-coloured components
Plastic push-in inserts like this one are commonly used to finish tubes and hollow sections. The anthracite colour (RAL 7016) provides a consistent appearance with other components in the same shade. The product is sold individually.

Selecting the right profile
The nominal profile size and wall thickness are the main factors when selecting an insert. This insert is intended for a 20×30 mm profile, and the compatible wall thickness range is given in the adjacent specification. The dimensions of the internal section, core and ribs, as well as the height of the external flange, are listed in the dimensions table.
