LaceLok® and IPC Standards: What You Should Know

Date Posted: 01/14/2026

We’re pleased to share an important update regarding LaceLok® and its alignment with industry inspection and acceptance standards. LaceLok was introduced to the market by DMC in 2020 as a solution to replace hand-tied lace and cable ties for secondary wire harness support. Since its launch, the system has gained widespread adoption among aerospace OEMs and MROs worldwide. Now, LaceLok is officially illustrated in IPC/WHMA-A-620 Rev. F, the standard for “Requirements and Acceptance for Cable and Wire Harness Assemblies.”

IPC standards, developed by the Global Electronics Association, are intended to eliminate ambiguity between manufacturers and purchasers while promoting product interchangeability and product advancements that enhance current processes. In IPC/WHMA-A-620 Rev. F, LaceLok is illustrated in the Securing section and is identified as a Cable Lacing Fastener (CLF). This section outlines proper securing methods, application considerations, and workmanship expectations for restraining devices used in wire harness assemblies. The IPC standard defines the acceptance criteria for cable lacing and harness securing, and when applied according to proper workmanship practices, LaceLok aligns with the criteria defined by the standard.

In addition to its inclusion in IPC/WHMA-A-620 Rev. F, LaceLok is supported by several other industry standards and classifications that qualify it for both military and commercial use as a secondary wire harness support device, including SAE International, ASTM International, and the DoD. These qualifications further reinforce LaceLok’s suitability for demanding applications where consistency, repeatability, and long-term reliability are critical. Collectively, the inclusion in these resources provides engineers, inspectors, and procurement professionals with greater confidence in the quality, safety, and reliability of LaceLok.
