Product details

This hybrid tongue and groove extrusion works perfectly with 12mm plywood panels. It is made of 6063-T5 aluminum and is 1.2mm thick.  Hybrid extrusions work just like traditional tongue and groove extrusion in producing a perfect seal between lid and base of the road case but achieving this with only one design. This helps to reduce material waste by 50%.

We have put together a list of matching hardware below for your convenience. If you are building a smaller case less than 800mm long you can choose the medium-sized surface mount lid stay instead.

This extrusion comes in 3 meters length and will be cut in half if shipping is required.  We offer to cut extrusions to sizes at extra cost of 1+GST per cut if you can provide a list of lengths.

To make your life easier, we offer below design and cutting service so that you receive everything cut to size ready to be put together:

  • Design and drawing: 100 to 300+GST depending on how complicated your case is.
  • Plywood panel cutting and routing: 65+GST per sheet of 1.22X2.44M
  • Foam cutting (EVA 5/10MM):65+GST per sheet of 1.5X3.0M
  • Extrusion Cutting: 65+GST
