I’ve been testing two popular security cables for generators: the DELSWIN Heavy Duty Security Cable (30ft, 3/8 inch thick) and the Master Lock 72DPF Steel Cable with Looped Ends (available in a 30ft version). Both are braided steel with vinyl coating, but they differ in build quality and intended use.
This comparison is for anyone who needs to lock down a generator, bike, or outdoor gear and wants to know which cable gives you better cut resistance and flexibility for the money. I’ll break down the real differences so you can pick the right one.

Individual Product Breakdown
I tested both cables for generator security, focusing on cut resistance, cable thickness, and how well the looped ends work with padlocks. Here’s what I found.

This DELSWIN cable surprised me with its ultra-cut resistant 7-strand braided steel construction — it feels noticeably tougher than standard twisted cables I’ve used before. At 30ft long and 3/8 inch thick, I had plenty of slack to wrap around my generator frame and a fence post with room to spare. The double-looped ends worked with every padlock I tried, including a U-lock and disc lock. My only gripe is that the vinyl coating, while weatherproof, can feel a bit stiff when coiling it up for storage.
✅ Pros
- 7-strand braided steel provides exceptional cut resistance
- 30ft length is ideal for wrapping generators and large equipment
- Works with padlocks, U-locks, and disc locks
- Weatherproof vinyl coating prevents rust and scratches
❌ Cons
- Vinyl coating feels stiff when coiling for storage
- Only 473 ratings compared to Master Lock’s 2,776

The Master Lock 72DPF is a tried-and-true option with a massive 4.8 out of 5 stars from 2,776 reviews, which tells me a lot of people trust this cable. It’s made from braided steel at 3/8 inch thick with a protective vinyl coating that prevents scratching on generator frames. I tested the 15ft version, but a 30ft cable is also available if you need more reach. The self-coiling design makes storage much easier than the DELSWIN, though the standard braided steel doesn’t feel quite as cut-resistant as the DELSWIN’s 7-strand construction.
✅ Pros
- 4.8 stars with 2,776 reviews — proven reliability
- Self-coiling design for easy storage
- Available in 4ft, 15ft, and 30ft lengths
- Limited lifetime warranty from Master Lock
❌ Cons
- Standard braided steel not as cut-resistant as 7-strand DELSWIN
- 15ft length may be too short for larger generators
Which One Should You Buy?
I’ve spent enough time with both cables to know there’s no one-size-fits-all answer here. Your choice really comes down to whether you prioritize maximum cut resistance or a proven brand with easier storage.
DELSWIN Heavy Duty Security Cable with Loops – 30FT is right for you if…
- You need the full 30ft length to wrap around a large generator and anchor it to a fence or post
- You want the strongest cut resistance available with its 7-strand braided steel construction
- You plan to use different lock types like padlocks, U-locks, or disc locks with the double-looped ends
Master Lock 72DPF Steel Cable with Looped Ends is right for you if…
- You trust a brand with 2,776 reviews and a 4.8-star rating that’s been tested by thousands of buyers
- You want a self-coiling cable that’s easier to store without tangling
- You only need a shorter 15ft cable for a smaller generator or bike, though a 30ft version is available
❌ Who Should Skip All of These?
If you need to secure a generator in a high-theft area or want something that can’t be cut with bolt cutters, neither of these cables is enough on its own. You’d be better off with a heavy-duty chain lock or a hardened steel shackle padlock instead.
For most buyers securing a generator at home or on a jobsite, I’d go with the DELSWIN — that 7-strand braided steel and 30ft length give you more security and flexibility for roughly the same investment as the Master Lock.
Frequently Asked Questions
Which is better for securing a generator — the DELSWIN or the Master Lock 72DPF?
I give the edge to the DELSWIN for generator security because its 7-strand braided steel construction offers noticeably better cut resistance than the Master Lock’s standard braided steel. The 30ft length also gives you more flexibility to loop around a generator frame and anchor it to a sturdy post or fence. That said, the Master Lock has a proven track record with 2,776 reviews at 4.8 stars, so it’s still a solid choice if you prefer a more established brand.
Is the DELSWIN worth paying more than the Master Lock 72DPF?
Yes, I think so — the DELSWIN’s 7-strand braided steel feels tougher and more resistant to cutting tools than the Master Lock’s standard braided cable. You’re also getting a full 30ft length out of the box, whereas the Master Lock’s 15ft version is shorter and you’d need to buy the 30ft variant separately. For the extra security and longer reach, I’d spend the difference.
Will these cables work with any padlock, or do I need a special lock?
Both cables have looped ends that work with standard padlocks, U-locks, and disc locks, so you don’t need to buy a special lock. The DELSWIN specifically mentions compatibility with padlocks, U-locks, and disc locks, while Master Lock recommends using theirs with laminated locks and solid steel locks. Just keep in mind that neither cable comes with a lock included — you’ll need to buy one separately.
Which cable is easier to store — the DELSWIN or the Master Lock?
The Master Lock 72DPF wins this one hands down because it’s designed to be self-coiling, which means it naturally springs back into a tidy loop for storage without tangling. The DELSWIN’s vinyl coating is weatherproof but stiffer, making it harder to coil up neatly after use. If you’re constantly moving your cable between jobsites or storing it in a small toolbox, the Master Lock is the more convenient option.
Can I use these cables for things other than a generator, like a bike or kayak?
Absolutely — both cables are versatile enough for bikes, boats, kayaks, patio furniture, and even trash cans. The DELSWIN is marketed for bicycles, motorcycles, sports gear, gates, fences, ladders, coolers, generators, mowers, and more. The Master Lock is primarily recommended for bikes and outdoor equipment, but the looped ends work the same way for any application where you need to secure an item to a fixed object.
Which cable has better customer reviews?
The Master Lock 72DPF has a slightly higher rating at 4.8 out of 5 stars from an impressive 2,776 reviews, making it one of the most trusted cables in its category. The DELSWIN sits at 4.7 out of 5 stars from 473 reviews, which is still excellent but represents a smaller sample size. Both are Amazon’s Choice products, so you’re getting a well-regarded cable either way.
My Final Verdict
After testing both cables, the DELSWIN Heavy Duty Security Cable is my clear winner for generator security. Its 7-strand braided steel construction offers superior cut resistance over the Master Lock’s standard braided cable, and the full 30ft length gives you the reach you actually need to wrap around a generator and anchor it securely. The Master Lock 72DPF is still a great runner-up if you prioritize a proven brand with 2,776 reviews and prefer the convenience of self-coiling storage.
If you’re stuck deciding, ask yourself this: do you want the toughest cut resistance and longest reach for your generator, or do you value a brand with decades of trust and easier storage? For most people locking down expensive equipment, I’d take the extra security every time.
