Cat proofing for rack mount
I just got this inexpensive unit to keep cats from chewing on the knobs and changing the settings the once I got a setting I liked:
You can still see the meters and lights, but the knobs and buttons won’t get accidentally (or intentionally) changed.
I used bread twist ties to put it on. For kids (who seem to love to twiddle knobs), I’d recommend bolts. lol.
