Who This Is For The Viper Guardian Shield is designed for dart board enthusiasts who need maximum wall protector coverage, especially in the critical lower area where most missed throws land. Whether you're a beginner learning proper technique or setting up a game room for casual players, this dartboard wall protector provides superior protection with its strategic extended coverage below the board. It's the ideal dartboard surround for households where multiple skill levels will be throwing. How to Use Simply slide the Guardian Shield directly onto your mounted 17.75 inch regulation sisal or bristle dartboard. No tools, drilling, or additional mounting hardware required. The surround fits snugly around your dart board and provides over 4 inches of protective coverage on sides and top, with significantly expanded coverage below where errant throws most commonly land. Within seconds, you'll have professional-level wall protection. What Sets It Apart Unlike standard dartboard surrounds that provide even coverage on all sides, the Guardian Shield features strategic extended protection in the lower scoring area. This design recognizes that most missed throws, especially from beginners and casual players, land low. The 1.5-inch thick high-density Polyshield EVA foam absorbs dart impacts without deteriorating, compressing, or allowing tear-through over time. Important Compatibility Note This dartboard surround fits all standard regulation 17.75 inch steel tip sisal and bristle dart boards. It is NOT compatible with 18 inch dartboards or soft-tip electronic boards. Please measure your dartboard before purchasing to ensure proper fit.
