CW-PA39 Cable Tension Clamp with Thermoplastic Wedge

Product Specifications

The CW-PA39 cable tension clamp anchors compatible messenger-wire cable arrangements using a body-and-wedge gripping design. Check the listed diameter, messenger construction and attachment geometry together when selecting this model.

Diameter selection: the specification table labels 3–9 mm as cable diameter, while the installation description identifies the messenger wire as the part inserted between the wedge and body. Send your cable cross-section drawing and the outside diameter of the member being gripped to confirm compatibility. Do not select by the overall cable diameter alone.

Load selection: 2.5 kN is the published breaking load, not an allowable working load or installation tension. Confirm the service-load requirements for your complete cable and anchorage assembly.

Product Advantages

Body-and-Wedge Messenger Grip

The messenger wire is positioned between the wedge and clamp body before the clamp is closed and tensioned. This gives you a defined gripping interface to check against the messenger dimensions and construction, rather than relying only on a cable trade name.

Weather- and UV-Resistant Thermoplastic

Both the body and wedge use thermoplastic specified for resistance to weather and UV radiation. This material selection addresses outdoor exposure. Include any required UV test method, exposure duration or operating temperature range in your inquiry so the supporting information can be checked.

Hot-Dip Galvanized Steel Bail

The steel bail has a hot-dip galvanized finish for corrosion protection. Check its connection geometry against your support fitting, and specify any project requirements for coating or environmental exposure before ordering.

Clear Material and Load Specification

The separate body, wedge and bail material descriptions help you compare offers against your purchasing requirements. Quote CW-PA39 together with the cable drawing so the proposed clamp configuration can be reviewed consistently.

Applications and Cable Selection

Consider CW-PA39 for overhead cable anchoring arrangements that use a compatible messenger wire and suitable support hardware. Its stated fitting method grips the messenger between the body and wedge; it should not be assumed to grip every cable jacket or conductor bundle.

• Messenger-supported cable installations: identify the member that carries the mechanical load and provide its outside dimensions.
• Replacement clamps: compare the messenger construction, grip dimensions and support connection with the existing arrangement.
• Project and wholesale purchasing: separate cable types and messenger sizes in your bill of materials to support accurate model selection.

For telecom, fiber-optic or power applications, submit the actual cable construction for review. A diameter within the listed range does not by itself confirm suitability for every material, jacket or load-bearing arrangement.

Installation Guide

The published fitting sequence is to open the clamp, place the messenger wire between the wedge and body, then close and tension the clamp. Use the following overview with the approved instructions for your exact assembly:

1. Confirm compatibility before fitting. Check the messenger dimensions, clamp condition and connection to the support fitting.
2. Open the clamp. Access the space between the thermoplastic wedge and body.
3. Position the messenger wire. Insert it between the wedge and body in accordance with the applicable fitting instructions.
4. Close and tension the clamp. Follow the approved tensioning method and specified load for the installation.
5. Inspect the completed assembly. Check seating, attachment security and the condition of the gripped member under your project acceptance procedure.

Confirm the required tools and detailed fitting method before field work. This overview does not define torque, span length, allowable service load or installation tension; those values must come from the applicable installation procedure and project design.

Frequently Asked Questions

1. What diameter range is listed for CW-PA39?

The published cable diameter range is 3–9 mm. Because the fitting description places the messenger wire between the wedge and body, provide the dimensions of that gripped member and your complete cable drawing to confirm fit.

2. Does the clamp grip the messenger wire or the complete cable?

The published installation description identifies the messenger wire as the gripped member. Do not assume the clamp can grip a complete cable bundle or optical cable jacket without a separate compatibility review.

3. What are the body, wedge and bail made from?

The body and wedge are weather- and UV-radiation-resistant thermoplastic, and the bail is hot-dip galvanized steel. Specific polymer grades and coating thicknesses are not stated; include them in your inquiry if required.

4. Is 2.5 kN the allowable working load?

No. The 2.5 kN value is a breaking-load specification. Your project designer must establish the allowable working load, installation tension and applicable design margin for the complete assembly.

5. Can CW-PA39 be used outdoors?

Its specified materials address outdoor exposure: the thermoplastic resists weather and UV radiation, and the steel bail is hot-dip galvanized. Confirm suitability for your particular temperature, coastal exposure or corrosive environment against the project requirements.

6. How is the clamp installed, and are tools required?

The stated sequence is to open the clamp, insert the messenger between the wedge and body, then close and tension it. Tool requirements are not specified in the published information; obtain the detailed procedure for both clamp fitting and the support assembly.

7. Is NFC 33-042 certification included?

NFC 33-042 is listed as a standard reference, which alone does not establish third-party certification. If your approval requires a certificate or test report, specify the required edition and document scope for confirmation.

8. What should I send for a bulk or customized quotation?

Send the CW-PA39 model, cable drawing, messenger diameter and material, required quantity and attachment details. Include the installation environment, mechanical requirements and required documents. For custom supply, describe the proposed changes so feasibility and order terms can be reviewed.

Request a CW-PA39 Quotation

Use the inquiry form below to send Hbcrownwealth your cable and messenger specifications, quantity and support-fitting drawing. These details help define the proposed supply and compatibility checks for your project.

If your requirement is a four-conductor service-line arrangement, review the CW-PA4/25 four-conductor tension clamp separately. Its specification is based on conductor count and cross-section, so it is not a direct replacement for a messenger-wire clamp.

CW-PA39 Technical Parameters

The listed diameter is labeled cable diameter in the product specification. Confirm it against the messenger wire that will be gripped between the wedge and body. Breaking load is not the allowable working load or installation tension.
