This arm attachment works with our Framed Gong Stand (model no. TMGS-3, sold separately) and allows you to add a second gong to that stand (one on top, one on the bottom). If you plan to use this arm on our Framed Gong Stand with two gongs, we recommend having a 38" diameter gong on the top and a 40" gong on the bottom (maximum). The arm is made from high-grade black powder coated steel to keep your gong safely secured as you play it, even allowing it to sway freely for the best sound. We've provided an allen wrench to get you up and going fast with putting this arm together. No extra tools or mechanical experience are required, and it comes together quickly and without hassle. Hang any gong cord from the two hooks located on the center of the arm—the hooks are deep in shape, keeping your gong cord secure which allows your gong to sway freely back-and-forth for immersive sounds. Designed in Germany, Meinl is a family-owned musical instrument manufacturing business that was established in Germany in 1951. Our expert German designers have deep relationships with our builders to ensure you're delivered the absolute finest quality.
