They are all available in the provided print profile.

This mount is part of a 19-inch modular rack mount system I designed. You can mix and match the modules with other mounts. Take a look at my models here to find out the other 19-inch mount modules.

Mount Assembly

OBS.: The modules used in this tutorial are only for illustration purposes, and I'm using them for the whole series. It might not reflect the models you download from this page.

• To assemble the parts, insert the 3 screws into the Right module.

• Then align it with the Left module.

• After that, insert the hex nuts in the screws, and using a screwdriver or allen key.

• Tighten the screws until you start feeling resistance and the nuts are securely into place. After that, you can install the mount in your rack.
