UL 1565: Cable Positioning Device Requirements

1. What does UL 1565 cover?

UL 1565 defines the construction and performance requirements for cable positioning devices—hardware used to route, retain, or position cables without serving as primary load‑bearing supports. The standard, harmonized with CSA C22.2 No. 18.5, applies to devices that keep conductors in place but are not intended to carry the mechanical weight of conduit, tubing, or cable. UL 1565 ensures that positioning hardware maintains its shape, retains cables securely, and performs consistently under installation and environmental conditions.

Devices covered include:

• Cable positioning clips
• Cable retainers
• Cable routing brackets
• Non‑load‑bearing cable organizers
• Similar devices used to position or guide conductors

2. How does UL 1565 compare to other UL standards?

UL 1565 is the standard for cable positioning devices, meaning it applies only to hardware that retains or guides cables without supporting their mechanical load. It sits alongside several other UL standards that cover different functions in cable management.

Comparable UL standards include:

• UL 62275 — cable ties and fixing devices (bundling)
• UL 2239 — load‑bearing supports (hangers, j hooks, straps)
• UL 514A / UL 514B — box supports and conduit fittings
• UL 2043 — plenum fire/smoke performance

Functional distinction:

• UL 1565 → positions cables (no load support)
• UL 62275 → bundles or secures cables
• UL 2239 → supports mechanical load
• UL 2043 → adds plenum suitability

If the device carries weight, it belongs under UL 2239, not UL 1565.

3. What types of products are evaluated to UL 1565?

UL 1565 applies to devices whose primary function is to position, retain, or guide cables without supporting their mechanical load. These products maintain routing, separation, and organization of conductors in a way that prevents sagging, misalignment, or abrasion. They are common in low‑voltage, controls, communications, and equipment‑level wiring.

Common UL 1565 product types include:

• Cable positioning clips used to maintain conductor alignment
• Cable retainers that prevent drift or movement
• Non‑load‑bearing brackets that define routing paths
• Plastic or composite routing devices used inside equipment
• Snap‑in or press‑fit retainers
• Low‑profile devices that maintain bend radius or separation

4. What does UL 1565 not cover?

UL 1565 excludes any device that carries mechanical load or functions as a support. It also excludes devices evaluated under other, more specific standards.

UL 1565 does not cover:

• Load‑bearing supports (UL 2239)
• Cable ties and fixing devices (UL 62275)
• Conduit fittings (UL 514B)
• Box supports (UL 514A)
• Raceway or wireway hardware
• Grounding or bonding hardware
• Fire‑protection or sprinkler supports

If the device holds weight, it belongs under UL 2239—not UL 1565.

5. How does UL 1565 define a cable positioning device?

A UL 1565 cable positioning device is hardware designed to retain, guide, or position cables in a fixed location without carrying their mechanical weight. The device may maintain spacing, prevent sagging, preserve bend radius, or keep conductors aligned with a routing path, but it is not intended to support the cable’s mass or transfer load to a structure.

Key characteristics:

• Non‑load‑bearing by design and test
• Intended for routing, alignment, or retention only
• Evaluated for retention strength and deformation resistance
• Not permitted to function as a hanger, strap, or support point

6. What mechanical tests are required under UL 1565?

UL 1565 includes a focused mechanical test suite that validates the device’s ability to retain cables securely under normal installation and environmental conditions. These tests ensure the device does not deform, crack, or lose retention strength when exposed to expected stresses.

Typical UL 1565 mechanical tests include:

• Retention force testing
• Deformation resistance
• Stress and strain evaluation
• Material integrity testing
• Environmental conditioning (thermal cycling or humidity exposure)

7. Are UL 1565 devices Listed or Recognized?

UL 1565 devices may be UL Listed for field installation or UL Recognized as components intended for integration into equipment. Listing is more common for standalone hardware used in building wiring, while Recognition is typical for devices installed inside equipment, appliances, or control panels.

Typical UL categories include:

• Listed positioning devices
• Recognized components for OEM or equipment assemblies

8. Does UL 1565 include fire, smoke, or plenum testing?

No. UL 1565 does not evaluate flame spread, smoke generation, or suitability for environmental air spaces. Devices intended for plenum use must also be evaluated to UL 2043. UL 1565 alone does not qualify a device for plenum installation.

9. Can UL 1565 devices be used in plenum spaces?

Only if the device is also evaluated to UL 2043. UL 1565 covers positioning performance; UL 2043 covers fire and smoke characteristics required for environmental air plenums. Both standards must be met for plenum installations.

10. Do UL 1565 devices have load ratings?

No. UL 1565 devices are not load‑bearing and therefore do not have working load ratings. The standard evaluates retention strength, deformation resistance, and material performance, but it does not validate the device for carrying the mechanical weight of cable, conduit, or tubing. Any device that publishes a load rating is not a UL 1565 device and must be evaluated under UL 2239.

11. Are materials and coatings relevant to UL 1565 performance?

Yes. UL 1565 evaluates the complete device, including materials, coatings, and construction. Material selection directly affects retention strength, deformation resistance, thermal stability, and long‑term durability.

Material considerations include:

• Plastic or composite formulation and resistance to cracking or creep
• UV resistance for outdoor‑rated devices
• Thermal stability for attic or equipment environments
• Mechanical resilience during installation and over time

12. Does UL 1565 apply to low‑voltage, PoE, and data cabling?

Yes. UL 1565 applies to the hardware, not the cable type. Positioning devices may be used with power, low‑voltage, communications, data, and PoE cabling, provided the installation complies with NEC routing and separation requirements.

13. What markings must appear on UL 1565 devices or packaging?

UL 1565 requires devices to be marked with the manufacturer’s name or trademark, the model or catalog number, and the UL Listing or Recognition mark. If the device is too small, markings may appear on the smallest unit container.

14. How can I confirm whether a product is evaluated to UL 1565?

Verification must be based on documentation, not appearance. To confirm UL 1565 evaluation, check the product or packaging for the UL mark, verify the catalog number, review manufacturer certification data, and search UL Product iQ. Only products explicitly evaluated to UL 1565 should be treated as UL 1565 positioning devices.

15. Can UL 1565 devices be used as supports if the installer believes they are strong enough?

No. UL 1565 devices are not evaluated for load support, regardless of perceived strength. Using a UL 1565 device as a support violates both the standard and NEC requirements. If the device carries weight, it must be UL 2239.

16. Can UL 1565 devices be used with cable ties or other hardware?

Yes, UL 1565 devices can be used with UL 62275 cable ties or other hardware, but only when the combination does not create a load‑bearing assembly. The positioning device may guide or retain the cable while a separate UL 2239 or UL 62275 device provides structural support. UL 1565 devices may be part of a routing system, but they cannot become the support system.

17. Does UL 1565 address installation spacing or intervals?

No. UL 1565 does not specify spacing or installation intervals. Those requirements are governed by the NEC. UL 1565 only evaluates the performance of the positioning device itself.

18. Are UL 1565 devices suitable for outdoor use?

Only if the device is specifically evaluated and marked for outdoor or UV‑exposed environments. UL 1565 does not automatically include UV or weathering tests. Devices intended for rooftops, exterior walls, solar arrays, or other sun‑exposed locations must be documented as UV‑rated or outdoor‑rated. Indoor‑only UL 1565 devices are not suitable for exterior installations.

19. What is the primary purpose of UL 1565?

UL 1565 ensures that cable positioning devices perform reliably, retain cables securely, and maintain their shape and function without serving as structural supports. It provides a clear distinction between positioning, bundling, and supporting hardware in electrical installations.
