Just like Schwarzenegger - I’ll be back!!!
We’re from out of state, so a resale supplier friend of mine turned me on to you guys. I just happened to be doing work right up the street and needed to come by for a bunch of fence post clamps and 4/0 cable...Not only did you have the 30+ clamps in stock, but you were able to run the bill on my suppliers account, and I was out in less than 20 minutes. I want to thank you for your quick service and killer stock...Just like Schwarzenegger - I’ll be back!!!

No second trip needed
...After calling a dozen or so other suppliers, Mayday was the only one with the lugs in stock! When I came down to will call, I ended up ordering two custom copper ground bars and a handful of cable tray jumpers. They made them as I waited, no second trip needed. Right on Mayday!

I felt like a seasoned pro
...I’ve never installed a chemical filled ground rod before in my life...Hell, I’ve never even seen one before this job...But after speaking with you I felt like a seasoned pro. I had the install done in less than three hours, and that was after moving the bore hole two times due to bedrock. Good looking out guys!!!...

Still the same great service and always smiling
I used to dealing with "Mayday Grounding" back in the early 90’s , back when they were Mayday Tool and Supply...I used to buy Milwaukee drills and concrete lutes from "Ully"...I couldn’t believe he was still there after all these years!!! He actually helped me with my ground tester order...Still the same great service and always smiling...

I'm writing this morning to thank you......
I'm writing to you this morning to thank you for your expert advice and professionalism in assisting me yesterday. The Burndy YH3931 connector and Y750 tool we rented from you worked flawless. Your assistance over the phone yesterday was very helpful and appreciated. I have used Mayday Grounding for a lot of different stuff and will continue to do so. These days it's not common to find individuals like you. Thanks again, and I look forward to future dealings.
