The Southwire Simpull THHN Play: What a Procurement Manager Actually Thinks About Their Cordless Phone

Simpull THHN is worth the premium, and their cordless phone is a situational tool, not a replacement for your standard desk phone. That's the short answer. I've been managing procurement for a mid-sized electrical contracting firm for the past six years, tracking about $180,000 in cumulative wire and tool spending. When we finally switched to Southwire's Simpull wire two years ago, it cut our pulling time by a solid 20%. But that clear cordless phone? We bought four, and two are sitting in a drawer. Let me explain.

Why I'm Not Just Another Reviewer

I'm not a salesperson. I'm the guy who gets the invoice for every spool of wire and every connector. I've negotiated with eight different vendors over the past half-decade, and I built a total cost of ownership (TCO) spreadsheet to justify our spending. My job is to find the point where quality, speed, and price intersect without getting burned by hidden fees.

When I audited our 2023 spending, I found we were wasting roughly $4,200 annually on labor inefficiencies directly linked to the wire we were using. Pulling standard THHN in 1-inch conduit through a 150-foot run? That took a team of three at least an hour. The wire would kink, the jacket would scuff, and we'd lose time. That's not a supplier problem—it's a product design problem.

The Simpull THHN Reality Check

Here's the thing: Simpull's jacketing is genuinely better. It's slicker. It pulls easier. According to our field crew, it reduces friction by about 25% compared to standard Southwire THHN. That might sound like a small number, but on a project with 5,000 feet of 10 AWG wire for a commercial install, that's time saved. Time is labor. Labor is the line item I care about most.

The kicker? The price premium for Simpull is about 8-10% over their standard THHN. If you only look at the line-item price, you'll think it's a rip-off. But factor in labor savings—even conservatively—and the break-even point is about 2,000 feet of pulled wire for a standard job. After that, you're saving money.

But don't take my word for it. Before our first big switch, I ran a test: 500 feet of 12/2 Simpull against 500 feet of standard Southwire THHN. Same crew, same conditions, same conduit. Simpull took 18 minutes to pull. Standard took 23. That's a 22% improvement. Multiply that by ten runs, and you've saved almost an hour of labor.

Watch out for the 'cheap' alternative, though. We tried a budget brand once that was 15% cheaper per foot. That 'savings' evaporated when we had to re-pull 1,200 feet because the jacket tore inside the conduit. The redo cost us $1,200 in labor and materials. The 'cheap' option ended up being 40% more expensive than Simpull on a TCO basis.

The Clear Cordless Phone: A Mixed Bag

Now, about that clear cordless phone. Southwire doesn't just make wire; they make tools and accessories, including these DECT 6.0 clear cordless phones. I bought four for our warehouse and shop floor. The idea is sound: a phone that extends beyond a standard desk phone's base, giving workers on the floor a direct line.

For our application, it's a niche tool. In a loud warehouse, the clarity is genuinely good. The DECT 6.0 technology eliminates interference from our power tools and motors. The range is also decent—about 150 feet from the base, which covers our main floor. We use them for the warehouse manager and the shop foreman, who need to be reachable while moving around.

But here's where it falls apart: battery life. The first unit we bought had a talk time of about 4 hours. For a phone that's supposed to be on all day, that's a deal-breaker. We had to implement a 'docking schedule' to ensure it was charged, which defeated the purpose of being mobile. We also found that the clear design, while aesthetically nice, makes it hard to see the screen in bright sunlight coming through the warehouse windows.

Would I buy them again? For the warehouse manager, yes. For general office staff? No. Their standard desk phone is fine. The cordless is a supplement for specific mobility needs, not a primary line.

How to Buy These Without Wasting Money

Based on my six years in procurement, here's my actionable advice on buying Simpull THHN and Southwire's cordless phones.

1. For Simpull THHN: Don't buy it by the foot for small jobs. The premium hurts more on 100-foot runs than 1,000-foot runs. Negotiate a bulk price with your distributor for a minimum of 2,500 feet per order. That's where the real savings kick in. We secured a 5% discount on our first bulk order by committing to a quarterly purchase agreement.
2. For the Clear Cordless Phone: Buy only what you need. Start with one unit for a high-mobility role. Test it for two weeks. I made the mistake of buying four up front, assuming it would be a no-brainer upgrade. It wasn't. Two are sitting in storage. Test before you splurge.
3. Total Cost of Ownership Checklist: When evaluating any tool or cable, use this checklist: base price + setup/installation fees + expected maintenance + labor savings/penalties + potential redo costs. Simpull usually comes out ahead on TCO. The cordless phone only wins if you have a clear need for mobility in a noisy environment.

Where This Doesn't Work

Honest talk: Simpull isn't for everyone. If you're doing mostly residential work with short runs under 50 feet, the premium over basic THHN is hard to justify. The labor savings just aren't there on small jobs. Stick with standard Southwire THHN from your local supplier.

Likewise, the clear cordless phone is a bad fit for quiet offices. It's designed for industrial environments. If your office is a standard commercial space, grab a standard Poly or Cisco phone instead. You'll save money and get better battery life.

And one more thing: don't expect this to replace your cell phone. The range is 150 feet, not 150 miles. It's a tool for a specific job, not a pocket device.

The Bottom Line

I've been tracking these numbers for years. Simpull THHN is a legitimate efficiency gain for commercial electrical work, but it's not for every job. The clear cordless phone is a situational tool that overperforms in a narrow use case and underperforms outside of it.

If you're a procurement manager like me, run the numbers. Don't let the unit price fool you. And for the love of all that is holy, test the cordless phone before you buy four of them.
