Sta-Kon RA1123M INS NYL FRK TRM 22-16 No6 RED BELT

The RA1123M takes 22 to 16 AWG stranded or solid conductor. That is the red color code band on insulated terminals, and the nylon insulation on this one is red to match, so you can spot the gauge range on a crowded panel without reading the stamp. Wire outside that range, 14 AWG and larger, needs the next size up (blue, 16-14) rather than this terminal.

It's sized for a No. 6 screw or stud. The fork (spade) tongue slides in around the screw without removing it, which is why these get used on terminal blocks, strips and device screws where a ring terminal would mean pulling the screw all the way out. If your block has a No. 8 or No. 10 screw, this tongue won't seat properly, you need the matching stud size.

A fork terminal like the RA1123M is the faster choice for maintenance work: you loosen the No. 6 screw, slide the tongue out sideways and the wire is free. A ring terminal is captive, so it can't vibrate off the screw, and that is what most codes and inspectors want on anything that moves or carries a motor load. Panels and control cabinets with a lot of landed conductors are where the fork wins on labor; vibration-prone equipment is where you should spec a ring instead.

Use a crimp tool matched to insulated nylon terminals in the 22-16 AWG red range. A nylon barrel needs a full insulation-supporting crimp nest, not a bare-terminal oval die, or you'll crack the sleeve. Standard color-coded insulated terminal crimpers index on the red position for this size.

Country of origin is the United States. Government, school and healthcare procurement that runs domestic-preference language typically wants that on record for terminations as well as for the big-ticket gear, so this one clears that question.

Nylon, not vinyl. Nylon sleeves take higher temperatures and resist abrasion and crushing better than PVC, so they hold up when conductors get pulled through a wireway or bundled tight in a control cabinet. It also means the insulation won't split as readily when a crimp die bites down on it.

Sta-Kon RA1123M. It's an insulated nylon fork terminal, 22-16 AWG, No. 6 stud, red, supplied in belt (strip) form rather than loose pieces, which is what you want if you're feeding a production or bench crimper.
