Mechanical cable assemblies — wire rope, push-pull cables, custom harnesses and terminated cable systems — have to meet a spec on strength, flex life and termination quality that varies a lot by industry, so the supplier you pick affects whether the assembly performs reliably in the field. This guide does not rank suppliers. It sets out the questions to ask and gives the same facts for each company so you can compare them yourself.
What should I check before shortlisting a mechanical cable assembly supplier?
Use these criteria for every company in this guide:
- Quality system: which certifications the company publishes, and at which sites.
- Where the assembly is built: the company’s own stated locations. Some suppliers list headquarters in one country and production in another, or name only one address despite describing a global client base.
- Product scope: whether the company builds custom assemblies to your specification, carries catalog/off-the-shelf products, or both.
- Material and construction range: what wire, cable or rope materials and termination methods the company states it works with.
- Scale and programme fit: headcount, facility count, or client volume the company publishes, and whether it suits your programme size.
Figures below come from each company’s own website unless marked otherwise. Anything a company did not publish is left out, not estimated.
Which mechanical cable assembly manufacturers and suppliers serve this market?
The six companies are listed in alphabetical order. Order does not indicate quality or preference.
Carl Stahl Sava Industries
- Founded: 1972 (“Since 1972, Sava’s produced the wire rope and mechanical cable Assemblies”).
- Locations: 4 North Corporate Drive, Riverdale, New Jersey 07457 — the only facility address the company’s own site names, despite describing clients “spanning the globe.”
- Certifications (company-stated): ISO 9001:2015; RoHS; REACH.
- Focus: custom mechanical cable and wire rope assemblies, cable fittings, pulleys, push-pull components and hardware/tools; materials include stainless steel, galvanized steel, tungsten and specialty strand wire such as nitinol; markets named include medical (surgical and robotics-adjacent assemblies), industrial, electronics, robotics and consumer.
Trade-offs:
- Strength: a wide material range, including nitinol, and a dedicated medical/surgical cable-assembly line, under one quality system.
- Limit: the company’s own site names only one manufacturing address despite its global client claims, so confirm where your assembly would actually be built; it does not publish IATF 16949 or ISO 13485, so ask directly if your programme needs either.
Cloom Tech (Hebei Cloom Electronic Technology Co., Ltd)
Cloom Tech is one of the six companies in this guide. Its facts below use the company’s own published figures, cross-checked against its live site where possible.
- Founded: 2017.
- Locations: Shijiazhuang, Hebei, China (headquarters and plant, 5,000 m² facility); Cavite, Philippines (plant, near Manila); Medley, Florida, USA (office).
- Certifications (company-stated): ISO 9001; IATF 16949 (company states valid to August 2029 — not shown on the live site checked in this pass); ISO 13485 (wiring harness business); IPC/WHMA-A-620E CIS (operator and inspector qualification — not shown on the live site checked in this pass).
- Focus: custom cable assemblies and custom wire harnesses built to customer specifications, serving 1,000+ cumulative clients since 2017 (company-stated); does not sell connectors separately, does not sell standard or pre-built cables/harnesses, and does not offer design services — it consults and provides professional recommendations only.
Trade-offs:
- Strength: a stated IATF 16949 certificate, a 5,000 m² facility, and a dedicated ISO 13485 line for medical wire-harness production.
- Limit: Cloom Tech builds in China and the Philippines and has a US office, so confirm where your assembly would be produced and what that means for lead time and cost; it does not supply off-the-shelf catalogue cables or harnesses, standalone connectors, or design services.
Cooner Wire
- Founded: 1957 (“Wired for Excellence since 1957”; the company’s own site also says “over 65 years”).
- Locations: 9265 Owensmouth Ave, Chatsworth, California 91311 — the only facility address the company’s own site names.
- Certifications (company-stated): ISO 9001:2015.
- Focus: custom cable assemblies, wire harnesses and molded interconnect cables; also makes hookup wire, multiconductor cable, flexible power cable, braided wire, medical cable, instrumentation cable, Litz wire, flexible wire rope and micro coax, from 42 AWG micro coax up to 4/0 AWG extra-flexible power cable; serves medical electronics, computer, telecommunication, robotic and semiconductor customers (company’s own site).
Trade-offs:
- Strength: an unusually broad flexible-wire size and construction range, with a dedicated medical-cable line.
- Limit: one named facility (Chatsworth, CA), so confirm lead time and capacity for your volume; the company’s own site publishes only ISO 9001, so ask directly if your programme needs IATF 16949 or ISO 13485.
Harbour Industries LLC
- Founded: 1965 (company’s own site).
- Locations: 4744 Shelburne Road, Shelburne, Vermont 05482 — the only facility address the company’s own site names; it is a Marmon | Berkshire Hathaway company.
- Certifications (company-stated): RoHS; REACH.
- Focus: RF & Microwave coaxial cables (its LL, LLS, SB, HF, HS and TRX families) and a separate Commercial & UL/CSA Cables line (NEMA HP3/HP4, UL-style, SE and STJ cables), for commercial and industrial customers (company’s own site).
Trade-offs:
- Strength: a dedicated RF/microwave coaxial-cable line plus a separate commercial/UL-CSA cable line, from one named US facility.
- Limit: much of the company’s own site is organized around a different product category outside this guide’s scope, so confirm which specific product line your assembly falls under; only RoHS/REACH compliance statements are shown for the product lines described here, so ask directly for the certificate that covers your build.
Kunshan RCD Electronic Co., Ltd.
- Founded: 2007 (“established in October 2007”).
- Locations: No. 1899, Huayuan Road, Zhangpu Town, Kunshan City, Suzhou City, Jiangsu Province, China — the only facility address the company’s own site names.
- Certifications (company-stated): UL; IATF 16949; ISO 13485; ISO 9001 (the company’s own site lists these in its main certification statement, but other sections of the same site also reference ISO 14001 and “TS16949,” so the certification list is not fully consistent page to page).
- Focus: custom wire harness and antenna manufacturing, including RF coaxial cable assemblies and connector harnesses (naming TE, Molex, JST, LVDS, flat cable, and quick-connect terminal/switch/plug assemblies), with an in-house R&D team and its own inspection equipment; stated customer sectors include biomedical, servo equipment, smart home, smart meters, new energy, automotive and robotics, among others (company’s own site).
Trade-offs:
- Strength: in-house R&D plus a broad connector and cable-assembly product range spanning several sectors.
- Limit: the company’s own site gives an inconsistent certification list across its pages, so ask for the specific current certificate before relying on any one page; it also names a single manufacturing address, so confirm capacity for your volume.
Nexans
- Founded: not independently stated; the company’s own site says “more than 140 years” of operation, without naming a specific founding year.
- Locations: operations across 41 countries (company-stated, corporate-wide); the pre-terminated cable-assembly product line reviewed for this guide is published on the company’s Norway site, which does not name a specific production facility for that product.
- Certifications (company-stated): not published as a company-wide quality certification (e.g. ISO 9001) on nexans.com as of this check; the pre-terminated assembly product page instead cites cabling/product standards (ISO/IEC 11801, EN 50575, IEC 60332) rather than a company quality certificate.
- Focus: pre-terminated fibre and copper LAN cable assemblies (its LANmark range), factory-terminated in fixed length increments for data-centre and structured-cabling use, within a broader global cabling and electrification business.
Trade-offs:
- Strength: a large global footprint (41 countries) and a factory-terminated assembly product line built to named cabling/fire-performance standards.
- Limit: the company’s own site does not publish a company-wide quality certification or a specific production-facility address for this product line, so ask for both directly before you order.
How do I choose between these suppliers?
- Match certifications to your buyer. If you supply a regulated or automotive programme, ask for the current certificate for the specific site that will build your assembly, not a general company statement.
- Confirm the build location. Several of these companies name only one facility address on their own site despite describing a global client base — ask for the plant address in writing.
- Separate catalog from custom. Some suppliers here carry off-the-shelf product families (coaxial, LAN, hookup wire) alongside custom assembly work; confirm which one you’re actually ordering.
- Check material and construction fit. Confirm the supplier states experience with your specific cable/rope material and termination method before you send a drawing.
- Test responsiveness. Send the same drawing or spec to two or three suppliers and compare lead times, questions asked, and documentation offered back.
