Review: It is a very good tool that gets the job done. - I bought this tool for my husband and he loves it very much. Review: Amazing! - I might be biased cause I like Klein tools but this has come in handy numerous times now. Plus I’ve been working more on electrical system where things have shorted out and the added electrical protection has come in clutch. These are a beast and definitely durable! Definitely worth the purchase! It’s bigger than I realized but it’s not too heavy either. ## Features - BOX WRENCH MEETS STANDARDS: ASTM 1505-10 standard 1000V rating - SEE-THROUGH INSULATING HANDLE: Confirms metal ends are not connected - 4 SIZES IN 1 TOOL: 1/2-Inch, 9/16-Inch, 5/8-Inch and 3/4-Inch sizes; 12 point sockets - REVERSE RATCHETING ACTION: With reversing switches on each end of the wrench - PROTECTION FROM DIRT AND DEBRIS: With enclosed gear mechanisms - 48 TOOTH COUNT: Higher gear tooth count helps reduce the swing arc - LARGER PAWL: Design can be switched even while wearing class 2 gloves ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006FXPYK2 | | Best Sellers Rank | #33,726 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #19 in Box-End Wrenches | | Brand | KLEIN TOOLS | | Brand Name | KLEIN TOOLS | | Color | Transparent | | Customer Reviews | 4.7 out of 5 stars 1,076 Reviews | | End Style | hang hole | | Finish Types | Painted | | Global Trade Identification Number | 00092644680281 | | Head Style | Box End | | Included Components | Lineman's Insulating 4-in-1 Box Wrench | | Item Length | 9 inches | | Item Package Quantity | 1 | | Item Type Name | Box wrench | | Item Weight | 11.2 ounces | | Jaw Capacity | 0.75 inches | | Manufacturer | Klein Tools | | Manufacturer Part Number | KT223X4-INS | | Manufacturer Warranty Description | 1 year manufacturer | | Material | Blend | | Material Type | Blend | | Measurement Standard | SAE (Inch) | | Model Number | KT223X4-INS | | Number of Items | 1 | | Operation Mode | Mechanical | | Package Quantity | 1 | | Point Count | 12 | | UPC | 092644680281 | | Unit Count | 1 Count | | Voltage | 1000 volts | | Wrench Length Style | standard | ## Product Details - **Brand:** KLEIN TOOLS - **Color:** Transparent - **Item Length:** 9 inches - **Item Weight:** 11.2 ounces - **Material:** Blend ## Images ![KLEIN TOOLS KT223X4-IN Lineman's Insulating 4-in-1 Box Wrench - Image 1](https://m.media-amazon.com/images/I/418yJEmQoaL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It is a very good tool that gets the job done. *by A***Y on January 23, 2026* I bought this tool for my husband and he loves it very much. ### ⭐⭐⭐⭐⭐ Amazing! *by J***S on June 2, 2024* I might be biased cause I like Klein tools but this has come in handy numerous times now.
