Klein Tools D5072 – Frequently Asked Questions
1) What sizes come in the Klein D5072 adjustable wrench set?
The Klein Tools D5072 set is two wrenches: a 6-inch (15.2 cm) and a 10-inch (25.4 cm), both extra-capacity adjustables. That pairing covers most electrical work, small conduit fittings and panel hardware with the 6-inch, larger bolts and fittings with the 10-inch.
2) Does the D5072 wrench set come in a case or pouch?
No case is included with the D5072. You get the two wrenches only, so plan on your own pouch or bag slot. Both handles have large loop holes, so they can be hung or tethered on a tool board or lanyard instead.
3) Are these Klein wrenches marked in SAE or metric?
Both. The jaws carry laser-etched SAE and metric size identification on both sides, so you can read the opening from either side of the tool without flipping it over on a fastener.
4) What are these adjustable wrenches made of, and will the finish hold up in a damp mechanical room?
6140 forged steel, heat treated, with a chrome plated finish for rust resistance. Chrome plating over forged alloy is the standard combination for tools that live in damp panel rooms and outdoor lineman work. The handles are forged with a soft-dipped plastisol grip.
5) Can these wrenches be tethered for work at height?
Yes. Both handles are designed with large loop holes so the wrench can be tethered or hung, which matters on tower, pole and lift work where a dropped tool is a safety incident. The set weighs 1.56 pounds total, so tether rating is a function of the individual wrench, not the pair.
6) Why pick an extra-capacity adjustable wrench instead of a standard one?
Extra-capacity means the jaw opens wider than a conventional adjustable of the same overall length. On the Klein D5072 that lets the shorter 6-inch body reach fasteners in tight panel and junction box work that would otherwise need a longer wrench you cannot swing. If you have open access and need more leverage on a large fitting, a longer standard wrench or a pipe wrench is the better tool.
7) What is the correct part number to order the 2-piece Klein extra-capacity adjustable wrench set?
Order Klein Tools D5072. That single part number covers the complete 2-piece set, the 6-inch and the 10-inch together, not an individual wrench.
8) Can you adjust these wrenches one-handed while holding a fitting?
That is what the knurl is for. The D5072 wrenches use smooth adjustment knurls for single-handed operation, so you can hold a conduit fitting or a box in place with the other hand while you close the jaw down.
9) How much space do I need to store the Klein D5072 wrench set in a tool drawer?
The longer wrench runs 10.25 inches overall length, 2.69 inches wide and 0.60 inches high, so a standard tool drawer or bag pocket takes it flat. Set weight is 1.56 pounds for both tools together.
10) Is it safe to slip a pipe over the handle for more leverage on a stuck nut?
No. Klein's own use instructions for these wrenches call for steady pressure without handle extension, and the fixed jaw should be set against the direction of turn. If the fastener will not move, go to a longer wrench or a striking tool rather than cheating the handle, which loads the adjustable jaw in the direction it is weakest.
