About the AA52081-B-2 Black Lacing Yarn, Size
This item is supplied to commercial item description A-A-52081 revision B, the specification that replaced MIL-T-43435B Type II for lacing and tying tape. Breyden Products describes tape to this specification as a flat braid manufactured from high tenacity, continuous filament polyester yarn, and offers it with a choice of finishes — Finish A (no finish), Finish B (microcrystalline wax), Finish C (synthetic rubber/elastomer), Finish E (vinyl) and Finish CSE (self-extinguishing). The finish code is truncated in this catalogue entry, so the finish applicable to this line should be confirmed at RFQ stage. Size 2 in the Breyden size range is 0.110 in wide by 0.015 in thick nominal, the second widest of the seven sizes offered, and the manufacturer quotes an operating range of −100 °F to 350 °F (−73 °C to 177 °C). This entry is the black colour.

Typical applications
At 0.110 in wide, size 2 is one of the broader tapes in the range, so it spreads clamping load over a wide bundle and is used for continuous lacing and spot ties on heavier wire harnesses rather than fine instrumentation looms. The black colour is generally chosen where the tie must be visually unobtrusive or where a light-stable tape is preferred over natural. Polyester lacing of this type is used in aircraft, UAV and defence electrical build and in MRO harness repair, where it avoids the hard edges and stress points of moulded cable ties.
