Ask any solar installer about the worst part of the job, and you probably won’t hear “the panels.”
You’ll hear about the wire.
Hundreds of runs of PV cable, all needing to be bundled, tied off and secured to racking before the inspector shows up. On a big commercial roof or a ground-mount array, that’s thousands of ties. And if you’re using traditional stainless steel cable ties, every single one means pulling out the crimper, lining it up and squeezing.
By mid-afternoon, your hands are sore. Do that every day for a whole season and it wears your crew down.
That’s exactly the problem the Heyco® SS-Lock Crimpless SunBundler® was built to fix. It’s a PVC-coated stainless steel cable tie that locks by hand. No crimper. No tools. Just loop, pull and move on.
Here’s why it’s worth a spot on your next install.
Meet the Heyco® SS-Lock Crimpless SunBundler®
The SS-Lock Crimpless SunBundler is a crimpless, PVC-coated stainless steel wire cable tie designed for solar wire management. It keeps everything installers already trust about steel ties and drops the part they hate.
In plain terms, you get:
- A stainless-steel wire core made from commercial aircraft grade 302/304 stainless wire
- A UV-protected vinyl (PVC) jacket wrapped around that wire
- A 304 stainless steel crimpless lock that grips by hand
You wrap it around the bundle, pull it snug and it locks. That’s the whole install.
The problems with solar wire management, and how the SS-Lock fixes them
Cable ties look like the cheapest line on the bill of materials. But how they go on affects your labour costs, your schedule and how long your system holds up.
- Crimping slows everything down
The problem: Every steel tie needs a crimping tool and two hands. Across a large array, that adds up to hours of extra labour. And if the crimper goes missing, the work stops until someone finds it.
The fix: The SS-Lock’s stainless steel lock grips by hand. Loop it, pull it snug and move on. No tools to carry, and none to lose.
- Crews get worn down
The problem: Squeezing a crimper hundreds of times a day is hard on wrists and hands. Tired installers work slower.
The fix: Heyco designed the crimpless lock specifically to minimize repetitive strain on the installer.
- Tool-free can feel like a compromise
The problem: Many installers assume that no crimp means a weaker hold.
The fix: The SS-Lock delivers up to 75 lbs of loop tensile strength with no crimping at all.
- Plastic ties struggle outdoors
The problem: Years of sun and freezing winters can leave standard plastic ties brittle. When ties fail, wires sag and you get callbacks.
The fix: Stainless steel wire inside a UV-protected vinyl jacket, rated -40°C to 105°C (-40°F to 221°F). It’s built for a hot July rooftop and a January morning in Alberta alike.
- Cable insulation needs protecting
The problem: PV wire insulation has to stay intact for the life of the system.
The fix: A smooth vinyl jacket covers the steel wire, so the steel itself doesn’t sit against your cable. Heyco designed it to prevent damage to cable insulation.

Where it fits best
If the job involves wire outdoors that must stay put for decades, the SS-Lock belongs on the truck:
- Utility-scale solar farms where tie counts run into the thousands
- Commercial rooftop arrays where speed and safety on the roof matter
- Residential solar where a clean, professional finish earns referrals
- Ground-mount and tracker systems that face wind, snow and constant sun
One tie, one motion, and your crew is on to the next run.
