The rear end of a scooter deck can come in 2 shapes for the most part: boxed and non-boxed. A boxed deck is when the entire deck profile continues to the back end. A non-boxed deck taper or angle is at the end of the deck, near your axle. The benefits to a boxed deck are that it will provide you more surface area to lock into grinds such as feebles, 50-50’s, and 5-0’s. A non-boxed or angled deck does not have this benefit, but being angled like this, it makes your deck lighter and more aerodynamic for tricks. Another added factor of non-boxed or angled decks is that you can install pegs on your deck to give you that extra surface area for grinds like a boxed deck.
