The Rock-N-Roller RSD2 Cart Attachment Ground Glider is a specialized transport solution for musicians and audio professionals who require reliable equipment mobility. This ground glider unit acts as a cart attachment that transforms compatible Rock-N-Roller transport carts into flat transport systems—ideal for moving heavy equipment on stages, in studios, and at venues. The robust aluminum alloy housing with concealed steel components supports up to 136 kg while maintaining a compact folded size of 89 cm in length, 30 cm in width, and 15 cm in height when not in use. Two rubberized wheels with a diameter of 20 cm and sealed ball bearings allow for smooth rolling on various surfaces, while a secure fastening system locks onto compatible cart frames without the need for tools. The flat design positions equipment just 8 cm above the ground for stability during transport and reduced lifting effort. The powder-coated surface resists scratches and corrosion from frequent use in different environments. This glider unit is particularly suitable for transporting amplifiers, speaker cabinets, mixing consoles, and bulky audio equipment, where reduced vertical lifting is advantageous. The RSD2 is the successor to earlier cart attachment designs and incorporates user feedback for improved fastening security and wheel durability. When unfolded, the unit reaches 122 cm in length and provides ample support for equipment up to 91 cm in width. Weighing in at 4.5 kg, the model remains portable while maintaining full structural integrity under load. All moving components use corrosion-resistant hardware for indoor and occasional outdoor use. This product addresses the practical need for efficient equipment transport in professional audio environments, where reliability and ease of use are prioritized over promotional features.
