Sta-Kon RG9711U NYL INSUL RNG TERM 90 DEG 2AN RED

Red is the color code on the RG9711U nylon insulated ring terminal, and on insulated terminals red denotes the smallest of the three common wire ranges (red, blue, yellow), with the Sta-Kon wire size designation for this part listed as 2AN. Match the color to the wire you are landing so the barrel crimps on the conductor properly rather than crushing it or leaving it loose.

The RG9711U is a ring terminal with a 90 degree bend between the barrel and the ring tongue, so the wire runs parallel to the mounting surface while the ring sits flat under the screw or stud. That is what you want in a tight panel, a motor terminal box, or behind a device where a straight terminal would force the conductor to make its own sharp bend. If the wire approaches the stud head-on with room to spare, a straight ring terminal is the simpler choice.

A ring terminal like the RG9711U is a closed tongue, so it has to come off the stud entirely to be removed, where a fork (spade) terminal slides out from under a loosened screw. The tradeoff goes the other way too: a ring cannot vibrate off a partly loose screw. For motor leads, grounding studs, and anything in a vibrating environment, the ring is the right call; for terminal strips you service often, a fork is faster.

Use an insulated-terminal crimper sized to the color code, red in the case of the RG9711U. A nylon-insulated barrel is crimped through the insulation, so the die has to be the insulated (oval or nest) type rather than the open-barrel dies used for non-insulated terminals. A plain pliers-style crimp will not hold the conductor to a reliable pull-out strength.

Nylon. The RG9711U uses a nylon insulating sleeve rather than vinyl, which is the tougher of the two against abrasion and nicking when terminals are packed tight in a gutter or pulled through a raceway. Nylon also resists deforming when the crimp is made close to the insulation shoulder.

The manufacturer part number is RG9711U under the Sta-Kon brand, and the country of origin is Mexico. That is the information most institutional and government submittals ask for on wire termination items.
