# Tube Connections

## Middle of Tube Connections

This connection is useful when adding a crossbar to the drivetrain frame to increase robustness and rigidity. It can also be adapted for assemblies with multiple tubes oriented in various directions. The holes on the WCP Tube Plugs follow the standard [1/2" Pitch Spacing](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing), making it a perfect fit for [Punched Tubing](/welcome/frc-build-system/system-standards.md#tubing).

Alternatively, the punched tube holes may be drilled out to a 3/8" diameter to clear the bolt head, allowing the use of a shorter #10-32 x 3/8"L bolt.

Any combination of tube sizes can be used in this example.

## Corner Connections

The corner connection shown below is an example of how teams can use the WCP Tube Plugs to easily build superstructures off the drivetrain using Punched Tubing. The holes on the Tube Plugs follow the standard [1/2" Pitch Spacing](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing), making them a perfect fit for [Punched Tubing](/welcome/frc-build-system/system-standards.md#tubing) and other common FRC components.

For this connection, we recommend drilling the bolt locations on the punched tubing to a 3/8" diameter to clear the bolt head, allowing the use of a shorter #10-32 x 3/8"L bolt.

Any combination of tube sizes can be used in this example.
