Global Specialties Solderless Breadboards

[Ground_Loop]

I have a large Jameco breadboard which is over 30 years old that I often fill up.  Now I'm looking for another one.  The Jameco I have has a metal back-plate, phosphor bronze terminals, screw attached rubber feet, quality binding posts and all the modules are attached with screws.  I'm considering a Global Specialties or 3M panel, but can't find complete info on the build quality.  In particular, I want the screwed down modules and plated phosphor bronze terminals.  I really don't want to build one up from parts, but cheap terminals and sticky back panel and rubber feet attachments are going to be non-starters for me.

I can verify all but the panel attachments.  I'd appreciate it if one or some of you can verify the screwed down panels.

My 3M boards have the large terminal strips attached with screws (from the back, not visible from the top). The two-row distribution strips are held on with adhesive. 3M boards are actually made by a company called Assembly Specialists and it's way cheaper to buy direct from them.

Thanks for the reply.  One on the way.

Looks like the they raised their prices a lot. Still cheaper than 3M, but not by nearly as much as before. 😭

I couldn't remember what the Assembly Specialist pricing used to be, but I checked before posting the link and they were still half of what Digi-Key had listed. The cost for my favorite #318 model is not much different from what I paid for the 3M version 15 years ago. But back when you first discovered AS, I remember it was only one third, so yeah, they have raised their prices considerably.

Old global specialities ones were very good. They went crap about 15 years ago though. 3M expensive.

Look around for Wisher ones.

Are Wisher the yellow ones? If so, I might have one. Never really liked that color.

Radio Shack used to sell re-branded AP Products/3M breadboards, equivalent to the #309. I bought a couple for around $20 each back in the late 1980s. But they haven't sold those for many years now.

The 3M boards pop up on eBay every now and then. Sometimes I see good deals, but I sure don't need any more solderless breadboards.

Wisher are the beige ones.

AP products ones were nice. Had one of their “powered” ones in the late 1980s.

Wisher breadboards generally come in either ABS (White) or POM (beige). E.g.:
