Use a gusset to fasten two aluminum extrusions together at right angles. The gusset is a right angle bracket that is easy to install and makes a strong corner connection. The gusset body is made from die cast aluminum and has integral alignment tabs that can be popped off as needed for cross t-slot joints as shown in one of the images below.
Several sizes of gussets are available depending on the profile size and nature of your application.
These gussets come with fasteners.
