- ACOUSTIC DAMPENING MATERIAL:Formulated from high-elasticity silicone with a tire tread pattern, these covers absorb ground friction to significantly reduce rolling noise in quiet areas.
- ENHANCED STRUCTURAL RETENTION:The expanded 0.4-inch side wrap design increases the contact area with the caster, ensuring the protectors remain firmly attached on rough outdoor terrains.
- STRICT FITMENT PARAMETERS:Exclusively engineered for double spinner luggage wheels measuring 2.0 to 2.4 inches in diameter with a minimum 2.8mm inner gap, ensuring precise compatibility.
- PHYSICAL WHEEL PROTECTION:By creating a resilient barrier, these silicone wraps prevent sharp debris from scraping suitcase wheels and stop dirty outdoor wheels from marking home floors.
- TOOL-FREE INSTALLATION:The flexible nature of the silicone allows the 8-piece set to stretch easily over standard dual casters, fully outfitting one complete 4-wheel suitcase instantly.
