Description
Rectangular tube insert 20×50 mm, anthracite

The Rectangular tube insert 20×50 mm in anthracite (RAL 7016) is a push-fit component that protects the ends of hollow sections. Made of polyethylene, it closes the open end, giving the structure a neat, uniform finish.
The insert has a flat outer flange and an internal section with several ribs that press against the tube walls. This holds the insert in place without additional fixings. It is designed for tubes with a wall thickness of 1.0 to 3.0 mm, allowing the same type of insert to be used with different 20×50 mm tube variants.
Applications
- protecting the ends of 20×50 mm rectangular hollow sections
- finishing frames, stands, supports and supporting structures
- closing the open end of a tube after cutting or assembling a structure
- neatly finishing exposed edges in dark anthracite

Inserts of this type are commonly used to close tube ends. Selection involves matching the tube's nominal dimensions and wall thickness to the ribs' operating range. The product is sold individually.
Polyethylene is commonly used to manufacture push-fit inserts, and this insert qualifies for small parcel shipping.
