The Viper Dartboard Leveler Kit is the perfect way to ensure your dartboard is properly mounted and stable. This kit comes with three leveler wheels so you can make pinpoint adjustments to stabilize your dartboard on any surface, including brick and stone. Simply attach each leveler around the outside of the dartboard and adjust their height for a secure fit. They are made out of a durable polymer that allows them to stand up to the force from any dart throw. The levelers are also completely reusable, so you never need to buy a new leveler kit. When you want to upgrade your dartboard simply unscrew them from the back and attach them to your new board.
