I've added and removed enough rads over the years and fit valves before, however I can't seem to buy any TRVs and Lockshield that have the normal hand turning lockshield in chrome; they all seem to just have this cap?

Are we saying I need a tool (bigger than any hex I currently own) to operate the lockshield each time?

Any explanation is helpful because I could just be a dunce...

After repeatedly smacking my head on the hydraulic arms of my bed, the only item I left in the room during the entire project, I'm fed up and want to hear others stupid injury or mishaps to lighten my own peripheral visions incompetence!
