Have you ever thought about what mechanism makes it possible for your desk chair to move in any direction? You can thank swivel casters for your ability to scoot in circles when you get bored. There are many mechanisms and hardwares like this which we encounter on a daily basis, yet rarely acknowledge. The number of tools and objects that have been invented to make our lives easier is vast, but here are three you should know, since you are likely to come across them often whether you realize it or not.
1. Nylon Zip Ties
Have you ever wondered why Barbies stay upright in their boxes? Most of us who have taken them out realize it is often thanks to nylon zip ties holding the doll in place. Invented in 1958 by an electrical company, nylon zip ties, also known as cable ties, have been used for a wide variety of purposes. Triangular teeth on one end hold a pawl irreversibly in place, allowing for a fixed position. They are often used at construction sites.
2. Cable Glands
To my ears, cable glands sound like something out of movie about robot people. In reality, cable glands are devices that work to secure cables to equipment and reduce straining. They can also be used to seal cables that have to pass through bulkheads. They are sealing and termination objects that are used in industrial, commercial and hazardous applications.
3. Rubber Grommets
Grommets in general are rings inserted through holes made in thin materials, such as cloth or plastic. Know how your shower is held up by rings passing through metal rings in the plastic sheeting? That is a grommet. Rubber grommets, though, are used more specifically to protect cords and wires. When wires pass through sharp edged holes, the holes can be abrasive and cut or wear the wires unless a grommet is added in between them.
