Klein Tools 2037EINS Long Nose Side Cut Pliers, 7-Inch Slim Insulated

The 2037EINS is a 1000V rated insulated plier, VDE certified, with molded insulation meeting IEC 60900 for insulated tools. The insulation is three-part with a white underlayer that shows through as a warning when the outer layers are compromised, and the handle is flame retardant and impact resistant. Klein is explicit that insulated tools only reduce the chance of injury on contact with an energized source: de-energize lines and equipment whenever possible, inspect the tool before every use, keep the uninsulated jaws away from energized parts, and destroy the tool if the insulation is damaged in any way.

That is what the slim profile is for. The nose tapers to a 0.094 inch point diameter with a 2.42 inch jaw length, and the jaw is only 0.375 inch thick and 0.688 inch wide, so it gets between conductors in a packed box without pushing everything aside. Overall length is 7.43 inches with 3.72 inch handles, giving reach and leverage behind the insulated grip. For panel and switchgear work where the tool goes in past live terminals, that thin insulated body is the main reason electricians pick this over a standard non-insulated long nose.

Look for the white layer. The 2037EINS uses a three-part insulation system with a white underlayer beneath the outer orange and gray covering. If you can see white showing through a nick, cut, or worn spot, the insulation may be compromised and the tool must be destroyed and replaced, not taped or repaired. Inspect before every use, and keep the handles clean, dry, and free of surface contaminants, since contamination can carry current across insulation that otherwise looks fine.

They cut. Side-cutting knives sit at the hinge, with a 0.572 inch cutting edge, and the knives are induction hardened for a long service life. That covers trimming conductors and snipping small wire as you go, so a separate pair of dikes is not needed for light cutting on the same task. The knives are the working edge, not a substitute for a heavy-duty cutter on large gauge cable.

The manufacturer part number is 2037EINS. The EINS suffix marks it as Klein's slim insulated version, so if you are matching a spec or reordering for a standardized kit, order by that full designation rather than the base long nose number, which is not insulated.

The 2037EINS uses a hot-riveted joint, which Klein specifies for smooth action with no handle wobble. The tool is forged in the USA from US-made tool steel and the cutting knives are induction hardened. For a fleet buyer standardizing an electrical crew or an MRO cart, that joint construction is the difference between a plier that still aligns at the tip after a year of daily use and one that starts missing the point.

At 0.30 lbs and 7.43 inches overall, the 2037EINS carries about the same as a standard 7-inch plier despite the insulation. The slim molded handles with small thumb guards are shaped to drop into a belt pouch cleanly rather than snagging, which matters when the insulated set lives on the belt alongside non-insulated tools.
