The ArcPlate Multiplate from Black Swamp Percussion is an accessory plate for mounting triangles. A clever design allows for mounting multiple triangles, or for hanging a triangle by two points when you need to play complicated rhythmic passages with two beaters. The arc shape gives clearance to the beater stroke path. The beater holders are designed so that BSP Spectrum Beaters stay securely on the plate even at an extreme angle. The versatility and functionality is inherent in the design, requiring no adjustment and no extra screws/nuts/bolts to lose. It is so compact it can even fit inside your BSP Triangle Gig Pack. Two slots are also on the plate for accessory mounts.
