Loos and Company Lock-Clad Assemblies

Lock-clad cable is manufactured by swaging an aluminum tubing over a 7x7 or 7x19 galvanized or stainless steel cable. Originally developed for aircraft control applications, lock-clad has found additional industrial applications where the following properties are advantageous:

  • Stretch is reduced substantially
  • Sag is virtually eliminated
  • A smooth cylindrical surface finish allows lock-clad to be sealed when routed through pressurized bulkheads
  • Vibration or "singing" is reduced

Lock-clad is supplied almost exclusively as a complete assembly with swaged fittings attached to fit the customer's needs. Since lock-clad is supplied rigid, the swaged on aluminum cladding can be removed at any point, for any distance, if necessary to pass over a pulley or perform a flexible action between two rigid sections. Loos and Company is an approved manufacturer for the QPL specification MIL-DTL-87218. For more information, or to receive a quotation for lock-clad assemblies, please contact us.
