Looks like someone has been decommissioning some server cabinets!
Superb pieces of kit. Rugged and reliable. You'll not find silver wire, fancy fuses or gold plated anything in them, but they genuinely do what they say on the tin. And keep doing it.
Of course, if you do want an Olsen with silver and so on, perhaps have a look at the LFD power blocks. Very similar design. Very different price.
