Parts of A Ladder

Parts of a Ladder

When it comes to home maintenance and repair, a ladder is one of the most important tools to have. But whether you have a stepladder or an extension ladder or a telescopic ladder, it’s important to know all the parts of a ladder in case you need to repair or replace any of them.

There are many different types of ladders, and we’re going to take a look at the parts of the most commonly used ones since most of them share several parts in common. By knowing all the different parts of your ladder, you will be able to repair or order the appropriate parts whenever necessary.

This information is also valuable when buying a new ladder because it will help you to completely understand the features being offered.


Different Parts of a Ladder


Parts of a Step Ladder

A lot of people own a stepladder that they use primarily for indoor repairs and maintenance tasks like accessing high shelves, placing the star on top of the Christmas tree, changing light bulbs, and so on.

Listed below are the different parts of a step ladder.

  • Cap:

This is the part of a ladder that helps to secure its center. The cap’s usefulness has evolved over the years, and now it comes with a tray that allows you to place your tools, screws, nails, or other items securely at the top of your step ladder.

  • Steps:

Well, I’m assuming we all know what a step is. This is part of a ladder that most people are familiar with. A step ladder typically has at least five steps, with the ones near the bottom being the widest and the steps at the top being the narrowest.

Steps are more or less the same across all ladders. Some steps come with treads to ensure traction. It’s always a good idea to buy a step ladder that comes with a non-slip design to enhance your safety while using the ladder. There are also some stepladders that have steps toward the pinnacle extending to the rear side rail allowing for a longer tray.

  • Spreaders:

These parts of a ladder lock into position whenever the rails are extended. They prevent the rails from splitting apart while also preventing the inward collapse of the ladder. They are metal bars that feature hinges that are lockable and connect to the rails (both front and rear).

The spreaders are hinged in the middle, a feature that allows the ladder to easily open and close, as well as to provide stability when the ladder is being used.

  • Rails:

These are the parts of a ladder that is vertical and to which the steps are attached. Stepladders have four rails – the front-left rail, front right rail, rear left rail, and the rear right rail. The front rails are the ones that are typically more substantial since they support the most weight.

  • Rear Side Rail

This refers to the other part or leg of the ladder which makes it possible for it to stand upright when it’s not leaned against something.

  • Shelf:

This is typically located very near the top of a step ladder and provides the individual working on the ladder with a small workspace where they can place tools, paint, or whatever else they are working with. The shelf locks in place securely in order to maximize stability.

  • Shoes:

This refers to the part of a ladder that keeps it from slipping when in use. Whenever buying a ladder, no matter what type it is, you want to make sure that it has shoes that are anti-slip.

Parts of an Extension Ladder

In addition to having a stepladder for jobs inside the house, most households also have an extension ladder to use outside for those tasks that require a longer ladder, such as cleaning gutters, repairing the roof, and so on. An extension ladder is certainly a great tool for all avid DIYers.

The parts of an extension ladder are a little different from those of a stepladder. We’ve listed some of them below:


These are typically the longest pieces that you’ll find on an extension ladder. There are four side rails since this type of ladder has two sections, and these are usually made from aluminum or fiberglass.


Instead of steps, an extension ladder has rungs that you climb. Rungs serve the same function as steps, but the rungs on the stepladder are only half as deep to allow the fly section to slide up and down. The rungs of an extension ladder have a dual purpose: they serve as ‘steps’ to stand on, but they also provide means of holding on to the ladder. Rungs are normally about 12 inches apart.

Fly Section:

This part slides up and down to double the height of an extension ladder. The fly section is arguably the most useful part of an extension ladder.

Base Section:

This part of a ladder is static which means that it doesn’t move in any direction. What it does is interlock with the fly section allowing the two sections to operate as a rail-type system.

Rung Locks:

Also called extension locks, these are the parts that knock the fly section in place, preventing it from collapsing. If you want to drop the fly section, all you have to do is hinge the rung locks upward, sliding them over the base rungs.

All aluminum or fiberglass extension ladders come equipped with locks to firmly hold the ladder’s upper section in place at each phase as the user changes the ladder’s height. When the section is raised, each of the rung locks is folded back. This allows free movement of the ladder’s rails and once the desired height has been achieved, the locks fold back and are secured in place over the lower rung.

Rope and Pulley:

The rope and pulley system is another very important part of an extension ladder. It allows the fly section to move up and down. To elevate the fly section, all you have to do is to simply pull the rope. Most aluminum or fiberglass extension ladders are in the 20 to 40-foot range, with two different sections attached to each other.

By extending the sections, you make the ladder longer in increments of about 12 inches. Operating the pulley system on either side of the extension ladder allows you to partially or fully extend it easily.


This is a safety feature that is located at the top of the ladder’s bottom section and it prevents the two sections from getting separated when the extension ladder is fully extended. Without a stop, the extension ladder would break apart into two sections.



As you can see, both ladders have parts in common that work in similar ways. However there are some differences and depending on which type of ladder you want to get, it’s important to know all about the different parts of a ladder.

Just keep in mind that no matter what type of ladder you get, it’s important to ensure that it is well constructed, has a good safety rating and that you follow safety guidelines for using the ladder to ensure that you avoid unnecessary accidents.
