Incorrect description. The wire range is actually 16-14 AWG, not 18-14 AWG. The label text on the packaging is blurry and looks like it might read 18-14, but after crimping some 18 AWG wire it became clear that the ring terminals were not rated for 18 AWG (loose, even after crimping up excessive damage). heat-insulating plastic). Panduit website confirmed this item is for 16-14 AWG only - too late to return as I didn't realize the description was wrong until I started using it.
