Cable management is a foundational element in every industrial or commercial setup. From factories and solar fields to warehouses and transportation fleets, organized wiring contributes to system reliability, operational safety, and maintenance efficiency. However, when traditional cable ties fall short due to size limits or restricted flexibility, the
HellermannTyton TELS-1 Extended-Length Tie provides an innovative solution.
Designed with a continuous reel of strap and separate heads, the TELS-1 tie gives users the freedom to secure virtually any bundle size without waste, over-tightening, or added installation complexity. Built from tough Polyacetal (POM), this tie system supports heavy loads and excels in outdoor, UV-exposed, and rugged environments.
This article breaks down what makes the HellermannTyton TELS-1 unique, how it performs under stress, and where it outclasses conventional cable ties.
What Is the HellermannTyton TELS-1 Extended-Length Tie?
The TELS-1 isn’t a typical one-piece cable tie. Instead, it’s a modular system consisting of:
- A 50-foot continuous reel of 0.5-inch wide strap
-
30 individual heads, each designed to engage securely with the strap
-
POM construction for both the heads and strap
-
UV-resistant black coloration for outdoor resilience
- A tensile strength of 250 lbs, offering superior load-bearing capacity
This design allows users to
cut the strap to any length, fit the head, and secure their cable or hose bundle precisely—without leftover material or the need to keep multiple tie sizes in inventory.

Key Features and Benefits
1. Custom Lengths Mean Zero Waste
Standard cable ties come in fixed lengths. When the tie is too short, it won’t work. When it’s too long, the excess must be trimmed and discarded. With the TELS-1, users cut the strap to the exact size needed—no more, no less. This eliminates waste and maximizes efficiency, especially in bulk installations.
2. Modular Design Reduces Inventory and Simplifies Storage
Rather than storing a wide array of cable tie sizes, one reel and a pack of heads can accommodate almost any bundle size. This is ideal for field technicians, facility managers, and contractors who need flexibility on the job site.
3. Smooth Strap for Cable Safety
The strap’s surface is smooth, with no serrated teeth. This minimizes the risk of damaging insulation, nicking hoses, or compressing fiber optic lines. It’s safe to use with sensitive materials, such as data cabling or medical tubing.
4. High Tensile Strength (250 lbs)
With a 250-pound load rating, the TELS-1 is a heavy-duty solution for securing large and high-tension cable bundles. It’s suitable for construction, mechanical installations, and industrial environments where reliability under stress is non-negotiable.
5. UV-Stabilized for Outdoor Use
The TELS-1 is formulated with a UV inhibitor, ensuring that it won’t degrade prematurely when exposed to sunlight. Whether on a rooftop solar array or highway infrastructure, it holds up in extreme outdoor conditions.
6. Temperature Tolerant
With an operational range from
-40°F to +185°F, the TELS-1 remains reliable across seasonal and geographic extremes. It won’t crack in freezing weather or soften in the heat.
Material Focus: Why Polyacetal (POM)?
Polyacetal, or POM, is a thermoplastic known for its:
- High stiffness and strength
- Low friction and wear resistance
- Excellent dimensional stability
- Chemical and solvent resistance
- Outstanding fatigue endurance
These characteristics make it ideal for mechanical components and high-load fastening applications. For the TELS-1, POM ensures that both the strap and the head retain structural integrity over time and under load—even in demanding environments.
Common Applications for the TELS-1 Extended-Length Tie
1. Solar Energy and Photovoltaic Installations
Solar arrays often involve large bundles of DC cables routed over long spans. The TELS-1 allows solar contractors to secure these runs without over-tensioning or resorting to multiple overlapping ties.
-
Use case: Securing PV cables to rail systems or panel edges
-
Advantage: UV stability and size customization on-site
2. Heavy Equipment and Vehicle Maintenance
In construction vehicles, buses, or railcars, wiring harnesses and hydraulic hoses require secure and durable fasteners. The TELS-1 provides the strength and flexibility needed to accommodate bundle variations.
-
Use case: Mounting wire looms in engine compartments
-
Advantage: High tensile strength and heat resistance
3. Warehousing and Logistics
In dynamic storage environments, cables often need to be bundled temporarily or redirected. The TELS-1 offers quick, secure fastening that’s easy to adjust without tools.
-
Use case: Organizing power cords for mobile racking systems
-
Advantage: Cut-to-length capability and tool-free application
4. Telecommunications Infrastructure
Server rooms and outdoor telecom cabinets contain cable runs of various lengths and thicknesses. The TELS-1’s adjustable strap length reduces clutter and helps keep equipment clean and safe.
-
Use case: Bundling fiber or Cat 6 lines in multi-rack setups
-
Advantage: Smooth strap won’t compress delicate data cables
5. Construction and Mechanical Systems
Mechanical, electrical, and plumbing contractors benefit from the versatility of extended-length ties during multi-phase construction.
-
Use case: Bundling conduit, copper piping, or insulation sleeves
-
Advantage: One reel supports all stages of installation

Installation Tips
To get the best performance from the TELS-1, follow these recommendations:
-
Use Shears or Cutters Designed for POM
Clean, even cuts make it easier to feed the strap into the head.
-
Don’t Over-Tension
The strap locks firmly into place—no need to overtighten. Doing so could compress or damage the bundle.
-
Inspect for UV Wear
While UV-resistant, all outdoor products benefit from periodic visual inspection. Replace any ties that show signs of fading or embrittlement.
-
Store in a Cool, Dry Place
The reel and heads should be stored away from direct sunlight until use to preserve shelf life.
Compliance and Safety
The TELS-1 Extended-Length Tie is both
REACH and
RoHS compliant, ensuring it contains no harmful substances that might limit its use in global applications. The
UL 94 HB flammability rating provides a basic level of fire safety for general-purpose cable bundling in compliant systems.
