  • VNH-23 military-grade jacketing
  • Velcro-style closure for easy install
  • National Stock Number (NSN) for 1" diameter

Hook-It® (VNH) is a cable management system that pairs VNH-23 military-grade jacketing with a Velcro-style hook-and-loop closure system. The PVC-coated VNH jacketing is 0.023” thick, as well as flame retardant and waterproof. This jacketing provides strong bundling and protection and is ideal for wires or cables exposed to harsh environmental conditions.

The Velcro-style closure is one of the easiest closure systems, as it requires no tools for installation. The nylon hooks and loops engage together to provide a secure closure, but can be easily pulled apart for quick access to wires or cables inside. The hook-and-loop material conforms to GSA specification A-A-55126, Type II, Class 1. The closure is sewn to the VNH jacketing with a black nylon thread.

Hook-It® (VNH) is offered in diameters ranging from 0.5” to 8”, with custom shapes and sizes available upon request. The 1” diameter has an assigned NSN for easy procurement. The operational temperature range of Hook-It® (VNH) is -65°F to 171°F (-54°C to 77°C).

Q:  What lengths of hook & loop jacketing are available?

A:  Our hook & loop closed sleeves can be ordered in lengths as short as a few inches to lengths of 100 feet or more.  When quoting or ordering, make sure to clearly state the length of each sleeve in inches, which is typically referenced at the end of the part number (-X120.0 for example).

Q:  What diameter of jacketing do I need?  Is it recommended to oversize?

A:  We will often suggest oversizing the sleeve diameter by 1/8” to allow for ease of installation.  If the application requires significant bending or flexing we will suggest even more extra room.  For assistance with sizing you can also contact one of our design engineers.

Q:  Can I cut the Jacketing?

A:  Yes*.  *We recommend ordering hook & loop closed
jacketing to the exact length required, but you absolutely can trim down a spool of Hook-It jacketing using standard scissors.   When cutting lengths of Hook-It jacketing, keep in mind the newly trimmed edges will not have the back-stitching found on
the factory edges and the stitching may come loose over time. For more details on cutting or size recommendations please contact one of our design
engineers.  

Q:  What is the minimum bend radius of the tubing?

A:  There is no minimum bend radius for our Hook-It products.  The flexible jacketing material allows for extreme amounts of bending and flexing.  The bend radius of the installed tubing is typically dictated by the harness it is covering.

Q:  What is the difference between Hook & Loop and Velcro?

A:  “Hook & Loop” refers to the family of closures that utilize small loops of fiber and tiny hooks to interlock and hold material together. Velcro is the name of the company that originally created the hook-and-loop fastening system.  Here at ZT we use Velcro brand fasteners as well as fasteners from other brands.
