Designed for standard 40x40 mm square steel tubing with a 3 mm wall thickness, this snap-fit end cap provides a clean and professional finish while protecting the inside of the profile from dirt, moisture, insects, and sharp edges.
The cap features internal retaining ribs that create a secure friction fit inside the tube. Rounded outer corners match the appearance of common steel profiles and provide a neat, finished look.
Perfect for:
- Workbenches
- Furniture frames
- Welding projects

- Workshop equipment
- DIY steel constructions
The model prints without supports and installs by simply pressing it into the tube.
