Are you feeling frustrated because you can't take your ES lampoholder apart?
You have either
a) purchased an ES lampholder which arrived assembled and can't take it apart
b) a need to troubleshoot an ES lampholder already wired and can't take it apart.
Why is this happening?
This is because ES lampholders have a safety lock. This prevents the lampholder coming apart when the lightbulb is detatched.
