Hitch Tubes

The coupling device tube, also known as the hitch tube or receiver tube, is an essential component of a towing system. 

Its primary function is to provide a standardized connection point for hitch-mounted accessories, such as ball mounts, bike racks, or cargo carriers.

The coupling device tube is typically installed at the rear of a vehicle, either bolted or welded to the vehicle's frame or chassis. 

It is designed to accommodate various hitch receivers, which can be easily inserted into the tube and secured with a hitch pin or lock.

Once the hitch receiver is installed in the coupling device tube, it creates a secure attachment point for towing. 

This allows for the connection of trailers or other towable accessories by utilizing a compatible coupler or hitch accessory.

The coupling device tube usually comes in different sizes or classes, which indicate their weight capacity. 

The most common classes are I, II, III, IV, and V, each with increasing load capacities. Selecting the appropriate class of coupling device tube depends 

on the towing needs and the vehicle's specifications.

By using the coupling device tube, you can easily connect and disconnect a variety of hitch-mounted accessories. 

This versatility enables you to tow trailers, transport bikes or sporting equipment, or add extra storage options to your vehicle.

Overall, the coupling device tube plays a fundamental role in towing systems by providing a standardized and secure 

connection point for hitch-mounted accessories. Its functionality allows for safe and convenient towing, expanding the utility of your vehicle for various applications.
