Actobotics Aluminum Channel Bracket A

well made and good for what ever you can build.

Good finish, robust part, very wide possibilities of use.

This is well made. The corners between the sides and end are sharp inside and out; this is not just bent to shape. Because of its basic form, however, you cannot expect it to have the same rigidity as a regular channel. A hub across the open end, and a couple of standoffs half way up, make a big difference.
