Hybrid Extrusion
Board thickness : 7.3mm / 5/16"

Unequal legs, perfect for offset hardware



Hybrid Tongue & Groove Extrusion - Mates with itself. Operates on a “mirror image” concept, almost like two W’s coming together when the lid closes. This not only provides for a much tighter lid closure, but is also a great benefit if you should make a bad cut. This way you don’t end up running short of either the separate tongue or groove.  One Hybrid extrusion plays the part of two traditional separate tongue & groove sections. Also see our calculation example below in determining the amount you'll need for your project (numbers are rounded for ease of understanding). If you have any questions regarding how this functions after taking a look at it, please refer to the FlexiCase Design Tool documents entitled "Hybrid Tongue & Groove Explained" and "Standard Split-Dish Twist Latch Cutout", or contact us, or see our video tutorial on hybrids.

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.

ALWAYS do a test fit with your sticks to familiarize yourself with how they mate before cutting.


NOTE: Even though the legs are a different length when you look at the cutaway, once the lid is closed, the design provides for an equal dimension of exposed extrusion on either side of the closure seam.

Having difficulty determining how much Hybrid T & G you need? The formula is easy and as follows:

Determine the total perimeter distance (circumference) of your case opening by adding up the length of each 4 sides that make up the case opening 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

So, 240" (which is 20 ft., which is 3 sticks) minimum amount of of Hybrid T & G required. But as we always recommend, it's always a good idea to purchase a little more than needed for unfoerseen errors. Better to have that extra stick than to run short in the middle of our project, or if you make a bad cut.

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.

All Cases utilizing 1/4" wall panels.

Typically, cases 130 pounds or less and, or, with an overal dimension of 120 inches or less (width + depth + height)

    Hybrid Tongue & Groove -1/4" (6ft.)

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

    I like the way these Hybrid T & G 1/4" fit my case making projects. The 1/4" material can be a bit flexible but this hardware maintains the form of my cases. Good product.

    I look like a pro!

    Posted by Nathan Moy on 24th Jun 2015

    In order to get a good fit, I strap my entire case together (with the lid in the closed position), make sure the groves are nested well and then put on the corners. These extrusions look great.

    Briliant design

    Posted by Jeanne on 2nd Feb 2015

    These hybrid extrusions are genius. I was able to cut my pieces in 10 minutes with a chop saw with minimal waste.

    Easy to use and nice closure - be mindful of construction details and use deluxe corner braces!

    Posted by Unknown on 11th Sep 2013

    This extrusion worked as I had hoped, however, keep in mind that one side of the channel is slightly longer than the other (this is clear to see in the dimensions photo). I only mention it for those that may notice. This will not pose a problem if you are using the large (deluxe) corner braces, but medium braces or smaller may not cover the gap that will be present in certain situations. Unless you cut a relief into perpendicular extrusions that butt against the tongue and groove extrusion, you will have this gap on the exterior of one side and the interior of the opposite. Having both sides of the channel the same length is the only thing that would make this product better. So I highly recommend using the deluxe corner braces in conjuntion with this for ease of construction and a uniform appearance. As always, communication and shipping time was excellent! Great experience with DIY Roadcases!

    Once I got the hang of it, I really like this compared to the traditional tongue and groove

    Better Than Others

    Posted by Eduardo Macias on 11th Dec 2012

    this tongue and groove is so much better than the other kind that is actually two different extrusions. the fit is so much tighter.
