This is a simple plastic guard to help block the attack of shoving a wire through a Sentry Safe led light (on similar safes), and pushing the solenoid down to unlock the safe.

You can see the attack at: https://www.youtube.com/watch?v=i7g-TvczpSw

I think the fill was set at something heavy (75%), and the other setting were generic.

Very simple part, would be nice for someone to add a plate that covers the front of the solenoid for more determined attacks. In the video, it seems that newer safes already have a steel cover over the solenoid. Mine does not.

Remove 3 screws that hold protective cover in place. You might need to remove batteries. I removed the left two solenoid screws, broke off the two washers on screws (for longer screw reach), then reused those same screws to hold guard in place.
