The complete product is inversely sewn in a tear-drop shape, using a “lock-stitch” with a high-temperature, mil-spec Kevlar thread.

The ZTT® (ALS-5) is able to cover many diameter cables and can be customized to fit virtually any length, allowing your installation to maintain its clean, professional appearance.

ZTT® (ALS-5) uses a jacketing material that is made from a light-weight, highly-flexible, woven glass fabric with a flame retardant, reflective aluminum heat barrier coating. The ALS-5 jacketing material can withstand continuous temperatures of up to 350.6°F.

The product is inversely sewn in a tear-drop shape, using a “lock-stitch” with a high-temperature, mil-spec Kevlar thread. This specific Kevlar thread is considered to be one of the most durable threads on the market today, resistant to bacteria, mildew, abrasion, age, and short-term heat burst exposure. During the sewing process, the product is turned inside out so that there are no edges when assembled, which reduces abrasion damage during installation.

Combining both of these high-temperature materials in one product produces a staggering 350.6°F, durable, 360° thermal protection product that is the perfect choice for applications that require high-temperature, pull-through, cable abrasion protection.


  • A complete 360° heat-reflective barrier
  • Operational temperature up to 350.6°F
  • Many different diameters and lengths available


  • Outstanding thermal barrier and abrasion-covering properties
  • Simply pull through your wires or cables, no tools necessary
