Here’s a quick and easy FAQ guide to help you in navigating and understanding trailer couplers more!
What is a Trailer Coupler?
A trailer coupler is one of the simplest and most basic products used in trailers and other similar vehicles. From its term alone, a trailer coupler is a component that “attaches” or “couples” a trailer onto a second trailer or another type of vehicle.
In other words, a trailer coupler is a connective point that mounts the trailer to the vehicle.
What Are the Parts of a Trailer Coupler?
Generally, trailer couplers are comprised of four (4) different parts:
This is the component that holds the vehicle to the trailer – it is the attaching point of a coupler.
The latch is the lock of a trailer coupler and is usually the component that is adjusted to be tighter or to be looser.
Handle or Lever
The handle (or lever, according to some companies) is the part that’s toggled in order to make the adjustments to the ball receptacle, going down to the latch.
Lastly, the safety clip is the part of a trailer coupler that ensures that the latch is in line with the lever and all other parts and components of the trailer coupler.
These four (4) make up the majority of trailer couplers you need. Missing one or any of these could be dangerous and hazardous.
What Are the Types of Trailer Couplers?
Traditionally, only two (2) types of trailer couplers are accepted and commonly used because of how some trailers and vehicles have been manufactured. These are the straight tongue and the A-shaped-tongue.
Out of these two (2), there are a few different styles for each of them:
For the straight tongue jack couplers, the variations of styles are:
- Straight Channel
- Foldaway Style
- Round Tongue Style
When it comes to A-shaped tongues, the classifications include, but are not limited to:
- Flat-Mount Style
- Adjustable Tongue Mount
- Lunette Ring Mount
- Gooseneck Coupler
NOTE: These different styles and types of trailer couplers are significant to a particular trailer mount or vehicle. Choosing the incorrect trailer coupler can lead to unfavourable results and dangers, which can lead to accidents.
What Materials Are Trailer Couplers Made Of?
Just like any other vehicle part or component, trailer couplers can be made from a wide range of raw materials and products, but the most common that we use (or our clients request from us) are stainless steel and aluminum.
In stainless steels, the particular product is 304 stainless steel. This is the most common for a number of reasons, but the majority of the decision comes at the fact that it is highly durable, resistant, and it’s extremely fashionable. This goes for both straight tongues and a-shaped tongues.
