Best way to anchor headphone jack in enclosure?

Thanks again to all of the contributors to the SamplerBox builds and this forum.
Quick question...I'm going to build an enclosure for my SB once I have everything put together, and I am using the USB DAC with headphone out. What is the best way to anchor this jack in place for the enclosure? I'm afraid if the headphone cord got stuck on something it would dislodge the USB DAC.

Thanks,
