CW-DLC D Cable Lashing Clamp for Messenger Strand

D Cable Lashing Clamp for Aerial Cable Installations

The CW-DLC D Cable Lashing Clamp provides a permanent termination point for lashing wire on messenger strand. You can use it when a lashing wire coil ends or where the continuity of a lashed cable run is interrupted. It helps you secure the wire end around the supporting strand.

This clamp fits messenger strand from 1/4 to 7/16 inch in diameter. Its grooved steel jaws grip the strand, while the stud, washers, and terminating nut secure the lashing wire. For ground wire applications, confirm conductor compatibility and your project’s electrical requirements before selection.

Features and Construction

• 1018 steel jaws: rolled and stamped from annealed steel to form the grooved clamping surfaces.
• Grade 5 steel stud: supports the jaw and wire termination assembly.
• Mechanical galvanizing: the listed coating specification is ASTM B695, Class 50, Type 1, providing a protective zinc finish for outdoor hardware.
• Staked stud ends: help keep the components together during shipping and installation.
• Defined strand range: one model accommodates 1/4–7/16 inch messenger strand, helping simplify your hardware selection.

The listed jaw material tensile strength exceeds 50,000 PSI. This value describes the steel material; it does not establish the clamp’s working load limit or the capacity of your installed cable system.

How the Clamp Works

The assembly separates strand clamping from wire termination. Tightening the clamping nut draws the grooved plates onto the messenger strand. The lashing wire then follows the specified route around the strand and into the termination area on the stud. The terminating nut holds the wire against the designated washer and shoulder surfaces.

Correct wire placement matters: pinching, crossed wire, or an unsuitable bend can damage the wire. Use the diagrams below to identify the components, and follow your approved installation procedure for the final assembly.

Applications and Product Selection

You can specify the CW-DLC for lashing wire terminations in aerial telecommunications and supported cable installations. Typical positions include the end of a lashing wire coil and planned interruptions in a cable run. For overlashing or ground wire termination, confirm the required washer arrangement and wire compatibility with your project specification.

Before ordering, check the messenger strand diameter, lashing wire material and size, installation arrangement, and coating requirements. The stated 1/4–7/16 inch range refers to the messenger strand, not the cable outside diameter or lashing wire diameter.

D Cable Lashing Clamp Installation Overview

1. Check the components. Inspect the jaws, stud, nuts, and washers. Confirm the strand size and required termination position near the cable support.
2. Position the clamp. Seat the grooved jaws on the messenger strand. Secure the strand clamping nut according to the approved installation procedure.
3. Control the lashing wire. Secure it with a suitable lashing wire grip before cutting or releasing tension. Remove slack using the prescribed field procedure.
4. Route the wire. Follow the strand’s natural twist and wrap the lashing wire around the strand twice. Bring it into the specified termination position between the stud shoulder and second washer.
5. Form the termination. Bend the wire around the stud as shown. Avoid a full 360-degree wrap around the stud, which can pinch or damage the wire.
6. Finish and inspect. Tighten the terminating nut to the specified installation requirement. Tuck the loose end clear of the cable sheath, then check wire seating, clamp position, and clearance.

For a second lashing wire or a ground wire, use the washer position specified for that configuration. Confirm the arrangement before tightening. Obtain the project’s required tightening values; no installation torque or assembly load rating is stated in this product listing.

Inspection and Maintenance

During scheduled line inspections, look for clamp movement, loose hardware, damaged wire, corrosion, or contact between a sharp wire end and the cable sheath. Replace damaged components and correct the cause of any movement before returning the assembly to service. Follow your network’s inspection and maintenance procedures.

Frequently Asked Questions

1. What is a D cable lashing clamp used for?

It secures the end of lashing wire to messenger strand in aerial construction, particularly at coil ends or interruptions in a lashed cable run.

2. What strand sizes does the CW-DLC fit?

It fits messenger strand from 1/4 to 7/16 inch in diameter, approximately 6.35–11.11 mm. Check the strand diameter when selecting the clamp.

3. What materials and finish are used?

The jaws are annealed 1018 steel, and the stud is Grade 5 steel. The components are mechanically galvanized to the listed ASTM B695, Class 50, Type 1 coating specification.

4. Can I use it to terminate a ground wire?

Ground wire termination is a listed application. Confirm the conductor size, material, washer position, and required electrical performance for your installation before use.

5. Does 50,000 PSI indicate the clamp’s load capacity?

No. It refers to the jaw material tensile strength. Ask for relevant assembly performance data if your project requires a specified holding strength or working load.

6. What information should I provide for a quotation?

Send model CW-DLC, required quantity, messenger strand diameter, wire specification, coating requirements, and delivery destination. Include drawings or inspection requirements for any project-specific request.
