Traditional rubber stretch cord, commonly called shock cord or bungee, is well known and widely used throughout the industrial, domestic and recreational world. This stretch cord consists of many strands of latex rubber filaments, bound together under braided polypropylene or nylon fabric. When stretched, the braiding opens slightly and UV penetrates to the inner core perishing the fine rubber strands, eventually causing failure. Consequently, stretch cords when exposed to the elements need to be replaced regularly.

The marine environment is the harshest for stretch cord where is subjected to extremely high ultraviolet (UV) bombardment and exposure to the elements. The Cordall team, with thirty years boating experience behind them, was convinced that there must be a better product available. However, after searching the marketplace in vain they decided to develop a product of higher performance specifications themselves.

Problem One: The Core

Conventional stretch cord is manufactured from inexpensive and low specification multi-strand rubber. Given its formation and with its large surface area, each strand in a traditional stretch cord is particularly vulnerable to UV damage. Banded strands also provide a capillary path for corrosive seawater and harmful chemicals.


Cordall developed a polymer of specially formulated rubber components which has a much higher specification than the traditional latex type cord.

Problem Two: The Cover

Traditional materials did not adequately protect the rubber interior allowing damage through UV penetration and contact with other destructive elements.


Cordall sourced a tightly braided 1000 denier polyester fabric pre-treated with a UV inhibitor to provide a barrier of protection. Together with the polyester cover, the rubber core has ample UV protection.

The result: Cordall's "Solcor" industrial shock cord

Having solved the problems of the traditional shock cord, Cordall then focused on the fittings and accessories. Some fittings already available, were suitable but many were not. So, a new range of streamlined, durable and reliable fittings using the latest materials and expertise were designed.

Cordall’s “Solcor” products integrate a collection of innovative ideas and improvements producing the ‘next generation’ of industrial-strength shock cord and fittings. Cordall has a reputation for durability, reliability and innovation making it the choice of quality. This was confirmed in the harshest and most demanding of tests during the Whitbread Round the World Yacht Race where Cordall products were used and passed with flying colours.

Cordall fittings and accessories are manufactured from UV resistant Nylon 6/6 for durability.

Most of our product range have been designed and manufactured in New Zealand.
