Overview
The MT474 is a 690V AC/DC Voltage Tester and is a designed to meet electrician’s requirements for a multitude of applications. The tester displays the voltage on red LED’s which increment as the voltage increases. There is an LED indication for polarity when DCV is measured. No switching of the meter on as the tester automatically turns on when voltage is applied to the two test probes. The MT474 incorporates a Low Impedance Test, which induces a basic load of approximately 6kΩ at 690 volts. The voltage tester can show the direction of the rotating field with three-phase systems, with the direction of field shown as L = anticlockwise and R = clockwise. The tester can be used as a Single Pole phase tester and measure continuity up to 400kΩ plus RCD Test. The MT474 meets the CAT IV 600V and CAT III 1000V safety standards.

I’m glad they made these.
Size: One Size
Bought these because I work with Klein tools and for the typical “where did you get those?” Or basically an excuse to talk about how cool I am for owning these. Highly recommend.

opens bottles!
Size: One Size, Style: Bottle Opener
This bottle opener is very cool. It’s like a screwdriver, but it’s really a bottle opener! It has a grip to prevent your hand from flying off while opening a bottle. I also carry a bottle opener on my keychain and am always especially proud when someone needs a bottle opener and I have on right there on my keychain.

Love this bottle opener. Looks and feels just like the screwdriver. Easy to grip just like the hand tools. Good gift idea for the electrician or a diy person that appreciates quality tools.

Great bottle opener and looks cool too
Size: One Size, Style: Bottle Opener
Love this opener. Matches with all the other screwdrivers in my tool box and have it ready to whip open a beer whenever needed. Slips into the pocket to carry with you as well. Solid tool and I gave a couple buddies one as a gift. These will see many years of beer opening super fast.
