I'm really happy to finally be able to carry a set of chocks in the plane wherever I go. These chocks are unique because they are stackable. This feature really cuts down on the amount of space required to carry them in the plane.
The durable plastic sides are lightweight, but are made to take a lot of abuse. There is space on the sides to put your airplane's n-number (you supply the vinyl lettering).
The edges of these chocks are made of non-skid material, so they stay where you put them. They also won't damage anything else in your baggage compartment.
