Why Choose Our German-Made Square End Caps?
These versatile square plastic end caps go beyond aesthetics. They are crucial for safeguarding floors and metal structures alike.
Floor Protection: Ideal as durable square furniture feet to prevent scratches, scuffs, and damage on valuable flooring surfaces (hardwood, laminate, vinyl, etc.).
Enhanced Tube Longevity: Acts as a robust square blanking plug, sealing the tube interior against environmental factors like moisture, dirt, and dust. This prevents internal corrosion and increases the lifespan of your metal tubes and box sections (SHS).
Safety First: Instantly covers dangerous sharp tube edges, providing a clean, safe, and professional finish required for public areas, schools, and contract furniture.
Superior Quality: Guaranteed precision and durability from expert German engineering.
Ordering Guide: How to Select the Correct Size
To ensure a secure fit for your square tube inserts, you must accurately measure the OUTER dimensions of your tube.
Example: If the outer dimensions of your tube are 30mm x 30mm and the tube has a wall thickness between 1mm - 2mm, then a 30x30mm insert will fit.
Wall Thickness Note: These inserts are suitable for tubes with a wall thickness between 1mm - 2mm.

Perfect solution.
The awning side rails on our campervan are 30mm x 30mm aluminium box section with a C track running along them for the awning. Rather than leaving the ends open we have inserted square end caps which are domed.
The result is a finish that looks professional and no wind noise at motorway speeds.
Perfect.
