The Take
Yes, the HEYCO 2717 Panel Plug is worth it. It is a no-frills nylon 6/6 Double D hole plug that snaps into unused strain-relief cutouts and stays there.
Electricians and panel builders buy it to signal competence, not taste. The part solves a real problem without turning the job into a procurement saga.
The Verdict
This is the definition of based hardware. It does one job, does it permanently, and costs pennies per use once you buy a bag.
Order it with your next drill bits. The plug pays for itself the first time a finger doesn't go through an open knockout.
