DMC's LaceLok® Cable Lacing Fasteners Receive Military Qualification

Daniels Manufacturing Corporation® (DMC) announces that LaceLok® is now qualified to MIL-DTL-32554 and MIL-DTL-32555. The technology is a direct replacement for lacing tape/string ties and cable ties for secondary support of wire harnesses and is now available for purchase.

Hand-tied lace and plastic cable ties have been the primary options for wire harness secondary support for over 50 years. Unfortunately, both methods present significant ergonomic, safety and consistency risks. Hand-tied lace often causes fatigue and repetitive motion injuries. It is also often applied inconsistently, as the applied tension can vary from operator to operator or across the duration of an operator's shift. Alternatively, cable ties offer a large profile that can damage adjacent cables and sharp edges after the excess cable tie is cut off. Plastic cable ties are also often less resistant to temperature range and various common chemicals. For these and other reasons, the U.S. military has prohibited the use of plastic cable ties on aerospace wire harnesses, per the Joint Services Manual NAVAIR 01-1A-505-1, but has approved LaceLok.

LaceLok combines the ease of cable ties with the abrasion- and chemical-resistance of lacing tape. The LaceLok system consists of LaceLok and the LaceLok Installation Tool. LaceLok is constructed with the same Nomex® lacing tape used in hand-tied lace. The Nomex lace is attached by aramid fiber thread to an ultra-high temperature thermoplastic fastener head. LaceLok can withstand extreme temperatures from -76°F to 500°F and is resistant to hydraulic fluid, jet fuel, lubricating oil, and isopropyl alcohol. LaceLok is offered in a variety of lengths, from 6 to 24 inches long and can be wrapped once, twice or three times around wire bundles to provide tensile strengths of 55 pounds to 165 pounds.

Using LaceLok is simple and ergonomic. The user wraps LaceLok around the bundle and squeezes the trigger two to three times to tighten, lock and terminate the fastener. The resulting loop force is controlled by the fastener, not the user.
