Greetings- Doing some organizing in our warehouse and came across a box full of some kind of demarc block. Four terminals on each side of a rectangular red dielectric block. Wh/Bl thru Rd/Bl pairs on each terminal with plenty of slack on each pair. The only number I could find on them is P-13171. Sound familiar??

Thanks in advance!!

Those sound like unprotected blocks that go inside ready access terminals, Reliable Electric #145B.

See page C-4 of THIS DOCUMENT (upper left of page). Is that what you have?

Darn Sure is. I know this isn't the place to post this but have no real use for these, so if anyone does let me know.

Thank You EV!!

They are rarely used anymore and even then, they are used by telcos for retro-fit use in older aerial terminals. I don't see why you shouldn't list them in the buy/sell category if you want.

There are some members here who work for smaller independent telcos who might have a use for them.
