National Braiding Industries key product range is the manufacture of kernmantle static ropes. Kernmantle is derived from the German word “kernmantel” which means “core and jacket”. The kernmantle rope is constructed with its interior core protected by an exterior braided sheath, designed to optimize strength, durability and flexibility. The “kern” or core fibres delivers the tensile strength whilst the “mantle” or sheath provides the abrasion factors. NBI kernmantle ropes are made exactly to standard and custom specifications. Static ropes allow access to and maintenance at the work site. They have moderate stretch which allows them to absorb sufficient energy to arrest falls.

The complete range of ropes manufactured by NBI include :
• Access Rope
• Yacht Rope
• Industrial Rope

The access rope manufactured by National Braiding is registered under the brand name of “Arresta”. ARRESTA® Rope is manufactured for use in the access rope, construction and all other difficult to access industries. Yacht ropes are used for marine applications, sailing and other sports primarily, but since the strength factors meet the climbing and caving requirements, these ropes serve a dual industry. Industrial rope is a general purpose rope supplied to various industries addressing numerous applications.

NBI ropes are coiled or spooled and supplied in shrink wrapped packages including instructions on the care, handling and treatment of rope, thus allowing for an optimum rope lifespan. Please refer to the attached “How to take Care of Your Rope” for detailed directions.
