• Suitable for critical aircraft harness applications, identifiable by a green coloured tracer

The physical dimensions of lacing tapes, coupled with the type of fibre used, will effect the overall strength of the finished tape. Generally, larger wire and cable bundles use tapes with a high tensile strength. The following tables provide the information required to select the lacing tape, for any given application requirement.

There are two form options available:

Braided flat lacing tape
• Used extensively throughout the aerospace industry
• Increased knot retention
• Ideal for applications requiring reductions in size and weight
• Good vibration performance with long term integrity and reliability

Round and twisted braided cords
• Good all-round performance
• Ideal for less demanding industrial and commercial harness applications

A wide range of lacing tape finishes are available that meet the requirements of the CID-A-A-52080 to CID-A-A-52084 (MIL-T-43435), as well as demanding industrial and commercial applications. Finishes are generaly used to improve a lacing tapes physical properties and performance characteristics. The following finishes are currently available, however not all finishes are available on all products. For further information please contact us.

Tensile Strength
The tensile strength will vary dependant on the material type and size. The tensile strength (breaking strength) of each product is thoroughly tested and measured in kilograms (KG). Please refer to the following tables or alternatively, contact us for assistance regarding your specific application requirements.

The standard lacing tape colours are natural and black, dependant on the type of material used. For further information on the additional range of colours available, please refer to the following tables or alternatively, contact us.
