Product details

If you are planning to build a light-weight travel case with 6mm plywood panels and smaller hardware, you will need this small ball corner among some other things. This is a 3-Legged small size ball corner made of 16 gauge steel with 3 mounting holes. It is 1.0mm thick for medium-duty use. We also offer a small flat corner if you prefer a flush finish.

If you might be shipping the case via a courier and transporting it in a truck we recommend you build your road case with 9mm or 12mm plywood panels and use the medium to large-sized flat corners and other hardware.

However, there is nothing wrong with travel cases build of 6mm plywood panels and smaller hardware like this one if all you need is a light-duty case that you can easily pull around.  We have put together a list of matching hardware and materials used for smaller cases made of 6mm plywood panels for your convenience:

This small ball corner for road case has 30mm offsets that allow it to hug the above mentioned single angled extrusions seamlessly. It has 3 rivet holes which make it faster to finish building your light duty protective case at home.

If you are building a road case with corner casters and pull out handles we have them in stock too. Feel free to contact us with any questions and don’t forget to share your finished case to our Facebook to claim your 20 dollars discount for your next project.
