HISTORY OF THE HUMBLE CABLE TIE
Weird how the simplest products are often the coolest?
Think of the cable tie for example. Nothing fancy about it – but indispensable nonetheless. From securing a banner to a fence, sorting out electrical cabling to protecting a padlock from unwanted entry, nylon cable ties have a myriad uses in both commercial and domestic environments.
But where did it all begin?
Well, as they say, necessity is the mother of invention. With the growth of the electrical, computer and telecommunications industries came a huge increase in the amount of cabling required to power up and network all the equipment. Historically, wires had been hand wrapped and tied, using such things as cords and adhesive tape. These methods were problematic however ...they weren’t only time-consuming but also led to issues with the cable insulation being compromised, the adhesive tape drying out etc.
Clearly, a better way of securing cables was needed. The answer came from a company called Thomas & Betts, an electrical and mechanical business who invented the very first cable tie, calling it a Ty-Rap. That was in 1958, and it was developed for use in aeroplane harnesses.
This design did have limitations however, as it involved making two separate parts and then joining them.
Since then, there have been significant improvements in the manufacturing process and the materials used to make cable ties. The next step was an all nylon, self locking cable tie. A major step forward was made in 1968 when a cable camp manufacturer in the USA, All-States became the first to produce a moulded one-piece nylon cable tie.
These days, there are a multitude of applications for cable ties, which now come in a diversity of styles and sizes. They are available from a wide variety of retailers, as well as from online cable ties suppliers, such as Australia’s Red2Go which sells quality products at wholesale prices.

Giant Contact Switch dropper seatpost review (Bike Radar)
Giant developed the Contact Switch post for their own bikes but it's also
available as an aftermarket purchase for 2012. It only comes in one size –
30.9mm – and needs a bit of TLC to keep it running smoothly, but it’s
potentially a top value option.
**Design**
The cable-actuated Contact Switch features 100mm (4in) of travel and can be
adjusted infinitely within that range using the handlebar remote. Not only is
it one of the cheapest remote dropper posts available, it also uses a separate
cartridge to house the air sprung and oil damped internals, which means much
less chance of contamination.
To keep both lateral shimmy and wear to a minimum, it features a proprietary
anti-twist system – the post runs on four triangular-shaped tracks on the
stanchion tube, instead of using the more common key-and-slot design.
Setup is quick but slightly fiddly, due to use of an internal cable clamp.
This gives the Contact Switch a sleek look but means you have to remove the
saddle clamp assembly and fumble around inside the seatpost head every time
you want to fit a new cable.
_Initial setup is a little cumbersome due to limited workspace ...
