DRILL TEMPLATE

Cut out this drill template, fold the edges and tape it to the enclosure. Before drilling, it’s recommended 
to first use a center punch for each of the holes to help guide the drill bit.

Ensure that this template is printed at 100% or “Actual Size”. You can double-check this by measuring 
the scale on the printed page.

Top jack layout

 assumes the use of closed-frame jacks like the 

Switchcraft 111X

. If you’d rather use 

open-frame jacks, please refer to the 

Open-Frame Jack Drill Template

 for the top side.

LED hole drill size

 assumes the use of a 

5mm LED bezel

, available from several parts suppliers. Adjust 

size accordingly if using something different, such as a 3mm bezel, a plastic bezel, or just a plain LED.
