Product Overview
Curtis T37040-16-0 Barrier Terminal Block: 16 Screw Positions with Solder Lugs on the Reverse
Condition
Unused, New Old Stock; clean and in excellent condition. The photos show a single-piece black molded barrier strip with sixteen bright silver-finish Phillips pan-head screws, each seated over a metal clamp plate. The reverse face of every position ends in a flat solder-lug tab pierced with a small hole. CURTIS and 37 are molded repeatedly into the underside between the barriers, with a small circular mark between them that is too fine to read reliably in the photos. Both end flanges carry a through mounting hole. Under close-up light the screw recesses show driver engagement marks and the black plastic shows light scuffing and stray lint from handling and storage; no solder, wire remnants, discoloration at the lugs, or thread damage are visible. Against the ruler the strip measures about 6.7 inches (roughly 17 cm) end to end.

Product Overview
The Curtis T37040-16-0 is a 16-position barrier terminal block from the Curtis series 37000 family, built for panel wiring where each circuit needs to stay separated and serviceable. Positions are on 0.375-inch (9.53 mm) centers and accept 22-12 AWG wire under the screw, rated 20 amps at 300 VAC. What the photos add to the spec sheet: this is a screw-to-lug strip, not a screw-to-screw strip. Field wire lands under the pan-head screw on the front face, and the matching connection on the back face is a flat solder lug with a hole in it for a soldered or wrapped wire. Molded end flanges at both ends carry mounting holes so the strip bolts flat to a panel or chassis without an extra bracket. The molded CURTIS and 37 markings on the underside make the part identifiable years later, after the label on the enclosure has faded.

- Machine repair tech replacing a cracked or burned barrier strip in a legacy control cabinet on 0.375-inch centers

- Instrument builder who wants field-serviceable screw terminals outside and permanent soldered connections inside
Frequently Asked Questions
Are there screw terminals on both sides of this block?
No. The photos show screws on one face only. The opposite face of each position is a flat solder-lug tab with a small hole through it, intended for a soldered or wrapped connection. If your application needs a screw on both sides, this is not the right strip.
What comes in the package?
One Curtis T37040-16-0 barrier strip exactly as photographed, with all 16 terminal screws installed and captive over their clamp plates. Panel mounting screws, jumper bars, and marking strips are not shown in the photos, so plan on supplying your own.
What does Unused, New Old Stock mean for this part?
It means the strip was never installed in equipment but has spent time on a shelf. Expect factory assembly marks in the screw recesses and light cosmetic scuffing on the molded body, as shown in the close-up photos. The wire range, current, and voltage ratings above come from the listing data rather than our own testing; verify them against the Curtis series 37000 datasheet before use in a rated circuit.
Why buy one or two of these instead of a bulk lot somewhere else?
Because a panel usually needs one barrier strip, not a carton of them. PartsMine sells the exact quantity you need, whether that is a single T37040-16-0 for one enclosure or a handful for a small production run, instead of forcing a lot of 10 or 50. Shipping is $8 flat rate and free over $28, and orders leave Idaho the same or next business day.
Barrier strips like this one are the quiet spine of a control panel: sixteen screws on the front, sixteen solder lugs on the back, and CURTIS molded into plastic where nobody but the next person servicing it will ever look. Wire it up and it goes back to being invisible, which is exactly the job it was designed for.
