Square tube insert 80×80 mm, pyramid, black

The black pyramid Square tube insert for 80×80 mm profiles is a finishing component that closes the open end of a hollow section. Made of polyethylene, with a pyramid-shaped external section, it gives the structure a neat, uniform finish.

The internal section has transverse ribs that enter the profile and hold the insert in place. This allows for push-fit installation. The insert fits profiles with a wall thickness of 2.0–5.0 mm.

Inserts of this type are used to protect the ends of steel and aluminium profiles in support structures, fences, railings and posts. They help prevent dirt from entering the profile and improve the appearance of the finished structure. The black colour complements dark profiles.

For installation companies, this is a simple, consistent finishing component, sold individually. Polyethylene is a material commonly used for protective components of this type.

When selecting an insert, the key factors are the external dimensions of the profile and its wall thickness, which determines how firmly the ribs grip the opening. The pyramid insert covers the edge of the profile and gives the end a neat, compact shape.

The ribbed push-fit section enters the profile, while the external section remains visible at its end. The insert is installed by hand by pressing it into the open end of the square profile.
