Double Angle Corner Extrusion. Double channels not only make assembly faster and easier, but provide maximum strength and integrity for case framework. See our cutting tips video tutorial
NOTE: Mill finish unanodized extrusions can commonly incur surface abrasions during shipment from rubbing together if they incur harsh handling during the shipment process. This is not abnormal, and is easy to remedy by rubbing the extrusions with some #0000 Fine Grade Steel Wool, cheaply available at any hardware store.

Rivets Required For Installation: Varies depending on length of section used, as well as associated parts that may be riveted through it.

Depending on your case design some rivets may require backing washers. Most rivets will install through the interior leg of the extrusion and therefore require no backing washers.

Having difficulty determining how much Double Angle Corner you need? The formula is easy and as follows:

Determine the total perimeter distance (circumference) of your case by adding up the width of each of the 4 sides that make up the case and multiply by 2

Example: If you have a trunk style case that is 40" side to side and 20" front to back, your formula would be 40+40+20+20 = 120 x 2 = 240

Then, multiply your case height (top to bottom) by 4

Example: If you have a trunk style case that is 20" high (top to bottom), your formula would be 20 x 4 = 80

THEN, add those two numbers together that you got from your two calculations, divide by 12, and this will give you the total footage required.

Example: 240 + 80 = 320 divided by 12 = 27 feet minimum required double angle extrusion. However, keep in mind that if you don't want to have seams anywhere on your case edges from butting two sections of extrusion together in one corner-to-corner stretch, then you'll need to determine the length of all of your double angle corner extrusion sections, and then purchase enough sticks to yield all of the required length pieces.  

And as we always recommend, it's always a good idea to purchase a little more than needed for unforseen errors, plus we rounded our numbers above for ease of understanding, so don't try buying just the exact amount of extrusion for a project. Better to have that extra stick than to run short in the middle of our project, or if you make a bad cut.

    Double Angle Corner Extrusion - 1/4" (6.5')

    Posted by Mark Powls -(MP Vantage Solutions, LLC) on 17th Apr 2023

    This extrusion is a must for 1/4" material if you want to maintain a rigid form to your lighter weight cases. Good product.

    Makes your project!

    This adds so much simplicity to the case design. My recommendation is to cut a small piece and take it with you when you buy your 1/4" plywood. If you're going to be using the laminate on the plywood, take a small piece of that also. You'll come home with the right plywood the first time.

    Solid product!

    Posted by Nathan Moy on 24th Jun 2015

    I mean solid literally. The cases feel sturdy when done. I only use my cases for local travel so I have been building them out of 1/4 plywood. The fit is good and the rivets secure the wood nice and tight.

    Good quality and the right size

    Posted by Jeanne Mitchell on 29th Dec 2014

    I found that the dimensions that I was using left little waste and that I wasn't fumbling too much with it in my basement. The aluminum feels pretty durable.

    I like the fact that it is shipped in 6.5' lengths. I like the product and it's great to work with.
