# How to estimate the materials?

## You have to estimate the quantities of materials before placing the order. Lacking materials will slow down the progress of a big project.

### 1. Firstly you will need a sketch of your project.

If you don't have any just draw a simple draft with a pencil. Trust me, this sketch will save you a lot of time even materials in the following steps.

### 2. Then we can divide the whole into several sections.

The rule of section division should be according to the use of terminals. That means the part you plan to use a pair of terminals, you should set it as a section. Mark on the sketch with the basic dimensions of each section, the height, length, cable space, post space.

### 3. Calculate the runs of each section.

That means the cable line number.

### 4. Calculate the terminal kits and wire rope.

Let's assume we have 2 sections and 10 runs for each section, the length of the section is 5 feet and 6 feet. Then we will need : 10 x 2 = 20 pairs of terminals (5+6)x10 = 110 feet of wire rope.

### 5. You will also need tools for installation.

Generally, you will need a cable cutter for cutting wire rope and a hydraulic crimper to swage the terminal end with cable, so the cable won't get loose under tension. If you are using ferrule type kits, a hand crimper is enough for ferrule crimping. Of course, if you are using swageless terminals, the crimper is unnecessary.
