Panduit SG350LH-L0 Super-Grip Light-Heavy Cable Tie, 15.3in, Black, 50-Pack

Overview

The Panduit SG350LH-L0 is a 15.3-inch Super-Grip® cable tie engineered for MRO, construction, and industrial wiring environments where standard ties slip, degrade, or lose grip under load. Built from weather-resistant Nylon 6.6 with a 534 lb tensile strength rating, this light-heavy cross-section tie holds wiring bundles firmly in place — even under the lateral forces common in vibration-prone panels or exposed outdoor runs. If you've had cable bundles shift in conduit or loosen in junction boxes after initial dressing, the SG350LH-L0's aggressive grip geometry is designed to stop that.

This is a cable tie with a design philosophy around bundle retention, not just bundle closure. The distinctive flared neck, wedge-and-hinge locking mechanism, and tapered tip all work together to prevent the lateral creep that wider, lighter ties permit. Panduit's Panduit wire management line treats these as a primary bundling solution for demanding environments — not a jobsite throwaway.

Key Features

• 534 lb Tensile Strength: At 534 lb, this tie handles high-count cable bundles in industrial panel builds without risk of strap failure under load — meaningful in environments where cable weight and pull tension accumulate over large horizontal runs.
• Light-Heavy Cross Section, 15.3in Length: The light-heavy profile gives you a wide, thin strap body that distributes clamping force across more bundle surface area, reducing the chance of jacket damage on sensitive cable. The 15.3in length accommodates larger bundle diameters than standard short ties — useful in structured cabling troughs or conduit stub-outs with multiple conductors.
• Nylon 6.6 Material, UV-Resistant: Nylon 6.6 retains mechanical properties through extended UV exposure, making the SG350LH-L0 a viable outdoor tie in direct-sun installations — rooftop cable routes, equipment pads, exterior junction boxes — where cheaper nylon grades chalk and become brittle within 12–18 months.
• Aggressive Tapered Tip and Flared Neck: The tapered tip self-guides through the head during one-handed installation, reducing installation time per tie in high-volume pull-and-dress workflows. The flared neck is the grip anchor — once locked, lateral movement of the bundle is resisted by the neck geometry, not just friction.
• Strong Wedge-and-Hinge Lock: The wedge-and-hinge mechanism locks with a definitive click and resists back-out under reverse tension — important in vibration environments (mechanical rooms, HVAC curbs, transport) where ratchet-only ties can walk backward over time.
• UL Listed (File #E56854), CSA Certified, RoHS Compliant: UL and CSA listings satisfy the compliance requirements of most commercial electrical inspections and industrial panel certifications. RoHS compliance keeps these ties within reach for installations subject to EU environmental directives or contractor specs that require RoHS on all materials. The specific UL file number (#E56854) is verifiable — not a generic claim.
• Rated for GTH-E, GS4H-E, GS4EH-E, PTH, STH2, and ST3EH Installation Tools: These ties are verified compatible with Panduit's hand and pneumatic installation tools, enabling consistent tail trim and controlled tension in production or panel-build environments where hand-tensioning varies by installer.

Integration and Compatibility

The SG350LH-L0 is spec'd for use with Panduit's GTH-E, GS4H-E, GS4EH-E, PTH, STH2, and ST3EH cable tie installation tools. If your team runs a high-volume panel build or wire harness operation, pairing these ties with a Panduit tensioning gun removes torque inconsistency from the equation — every tie gets the same tension and flush trim. For lower-volume use, the tapered tip installs cleanly by hand without a tool.

Pack quantity is 50 ties per package, with a carton quantity of 500. For wire management projects requiring bulk quantities — structured cabling pulls, industrial control panels, field service kits — the 500-count carton keeps per-unit cost predictable and eliminates repeated reordering mid-project.

Frequently Asked Questions

Q: What is the tensile strength of the SG350LH-L0?

A: The SG350LH-L0 is rated at 534 lb tensile strength, making it suitable for high-count or heavy cable bundles in industrial and MRO environments.

Q: Is the SG350LH-L0 suitable for outdoor UV-exposed installations?

A: Yes. The SG350LH-L0 is manufactured from Nylon 6.6, which is weather-resistant and rated for intense UV environments. This makes it appropriate for outdoor cable runs, rooftop equipment pads, and direct-sun applications where UV degradation is a concern.

Q: What certifications does the SG350LH-L0 carry?

A: The SG350LH-L0 is UL Listed (File #E56854), CSA Certified, and RoHS Compliant. These listings are verified for this specific SKU.

Q: What installation tools are compatible with the SG350LH-L0?

A: Panduit specifies the SG350LH-L0 for use with the following Panduit installation tools: GTH-E, GS4H-E, GS4EH-E, PTH, STH2, and ST3EH. It can also be installed by hand.

Q: How many ties come in a package versus a carton?

A: Each retail package contains 50 ties. A full carton contains 500 ties (10 packages).

Q: What is the overall length of the SG350LH-L0?

A: The SG350LH-L0 is 15.3 inches in overall length, providing capacity for larger bundle diameters compared to standard short-length ties.

The SG350LH-L0 gets specified on commercial and industrial projects where installers have learned the hard way that standard-grade ties lose grip over time — particularly in environments with thermal cycling, vibration, or UV exposure. The 534 lb tensile rating and Nylon 6.6 construction aren't marketing specs; they're the numbers that matter when you're dressing a 40-conductor bundle on a rooftop equipment pad and the next inspection isn't for 5 years.

Technical Highlights:

• 534 lb Tensile Strength: This is meaningfully higher than economy-grade 18 lb or even mid-range 50 lb ties. For dense industrial wiring bundles in control panels or cable troughs, this is the spec that keeps the bundle dressed after the panel is bolted shut.
• Nylon 6.6 UV Resistance: Generic nylon (Nylon 6) degrades under prolonged UV — chalking, cracking, and losing tensile strength within a few seasons outdoors. Nylon 6.6 holds structure significantly longer in direct-sun outdoor environments, which is why Panduit specifies it for intense UV use.
• UL Listed File #E56854: Having a specific, verifiable UL file number means this tie will pass inspection on listed commercial electrical work without substitution questions — important when an AHJ or general contractor's spec sheet calls out listed cable management hardware.

Deployment Considerations:

• For high-volume pull-and-dress work, match these to the compatible Panduit tool (GTH-E or GS4H-E for hand tools; STH2/ST3EH for pneumatic) — consistent tension and flush trim at 50+ ties per hour is not achievable by hand at the same quality level.
• The 15.3in length is the right fit for large bundles, but oversizing a tie for a small bundle reduces the wedge-lock engagement — size your tie to the actual bundle diameter for maximum lateral retention.

For panel builders running UL 508A-listed control cabinets, or field teams dressing exterior cable routes where re-entry for retying is not practical, the SG350LH-L0 (often searched as SG350LH L0) is the correct specification — not a step up from economy, but the right starting point for work that needs to hold.
