How to choose trolley case accessories
Tie rod: The material of the tie rod is usually aluminum alloy, steel, and the structure is one-section, two-section, and three-section. Two-section type and three-section type means that the length of the pull rod can be adjusted according to the weight of the box. Generally, the three-section type is used for 20 inches and 24 inches, and the two-section type is used for 28 inches. When purchasing, the lever must be built-in and made of steel or all-aluminum. The all-aluminum is lighter and sturdy. Otherwise, you can’t handle brutal loading and unloading.

Roller: The material of the roller is usually rubber, wear-resistant, shock-absorbing, and low noise. It has built-in and external ones.
The built-in roller is generally called a one-way wheel. The advantage is that it is durable and can withstand the brutal handling during consignment. The disadvantage is that it cannot be changed at will. It is suitable for any road surface in towns, railway stations, and bus stations;
External rollers are usually called "universal wheels" because they can roll in any direction. The advantage of the "universal wheel" is that the trolley box can change direction at will with the movement of your body during operation, but its disadvantage is that it cannot withstand the brutal loading and unloading during consignment and is suitable for walking on smooth roads;
The external rollers are generally divided into 4 wheels and 8 wheels, which are the so-called single-row wheels and double-row wheels. In terms of robustness, single-row wheels are better than double-row wheels;
