The KM-212 Wheelchair Tube Clamp Dual Knuckle represents a significant advancement in the realm of assistive technology, specifically designed to enhance the functionality and independence of wheelchair users. At the forefront of this innovative product is the L size (9") Super Knuckle Arm, which boasts a ball head with a 1/4”-20 female thread. This feature aligns seamlessly with KUPOCARE Switch Mounting Plates making the KM-212 a versatile tool for various AAC switches and devices. The arm's unique construction, which includes linking two S size arms with a 3" extension, provides an unparalleled range of motion. This design is further enhanced by the inclusion of four ball heads on the arm, allowing users to adjust their mounted AAC switches to the most suitable and comfortable positions. The additional flexibility comes from the extension arm, equipped with multiple thread holes, enabling the attachment of various devices using an extra Super Knuckle Arm.

The core of the KM-212's design is its Wheelchair Tube Clamp, a component that epitomizes stability and adaptability. This clamp, fitted with a ball head, effortlessly integrates with the Super Knuckle Arm, creating a secure and stable base when attached to wheelchair frame tubes. To cater to the diverse range of wheelchair tube diameters, the clamp includes three plastic spacers and a rubber strip. This thoughtful design allows it to fit tubes from 3/4" (19 mm) to 1-1/4" (32 mm), ensuring wide applicability across different wheelchair models. The clamp's ease of use is evident in its recommendation to remain installed on the wheelchair, thereby simplifying the process for users by eliminating the need for frequent remounting. The detachable nature of the Super Knuckle Arm, achievable by simply loosening the central knob, adds to the overall user-friendly design of the KM-212.

Beyond its primary role, the KM-212 showcases its versatility in various applications. Its design is not limited to mounting AAC switches alone; it can also support any equipment that has a 1/4"-20 male thread. This feature extends to creative uses, such as the construction of a "homemade Velcro mounting board with ball head," as demonstrated in a tutorial video. This innovative approach allows for the easy mounting of lightweight devices like AAC switches and joysticks onto a board using Velcro tapes. Users benefit from the ability to freely adjust the angle of the mount with the Super Knuckle Arm, offering a level of customization that greatly enhances the functionality and independence of wheelchair users. The KM-212 is more than just a mounting tool; it represents a commitment to empowering individuals with mobility challenges, providing them with solutions that facilitate ease and efficiency in their daily activities.
