"Safe Blocks" / mains quick connection terminals

[tomizett]

Hi All,
Here's a random (and not very interesting question). We have a requirement for a "safe block" style rapid connection system, similar to this:

Cliff CL1850 Quicktest Mains Connector

Cliff - CL1850 - Cliff CL1850 Quicktest Mains Connector - <p>The Quicktest is ideal for laboratories and service and test departments where a safe, temporary

Our particular requirement is that the connector have a metal contact on both sides of the jaw - the Cliff products (as above) have a single metal contact and a plastic rocker that holds down the wire. We need to connect a flat enameled copper wire which is scraped clean on one side only - therefore we need a two-sided connection so that the orientation of the wire is not important.
The older style of safe block (as sold by RS) used to have an all-metal connector, and were ideal - however these are no longer manufactured.

Does anyone know of other manufacturers/suppliers, besides Cliff, who make a similar mains test connector block?

Thanks!

It is a long time since I used a safeblock.

A quick googling always seems to result in the Cliff test connector which you have found.
So I cannot help with an alternative model.

However, have a look at the Wago 221 series connectors:

221-412 | WAGO 221 Series Lever Connector, 2-Way, 32A, 24 → 12 AWG Wire, Cage Clamp Termination | RS

Would these be any use in your test environment?

Thanks guys. The Wagos are good, but might be a bit fiddly - however they might be worth considdering.
Funily enough, the item in that ebay link is identical to the ones curently in use (although ours have an RS sticker where this has a picture of a seahorse). Sadly long since out of production.
I was expecting to find hoards of cheap imitations on Banggood etc, but it seems not... maybe Cliff enforce their patents hard?

I suspect it's more a question of little interest in them?, we had one at work once, no one ever used it.
