VERIFY BOTH MEASUREMENTS BEFORE ORDERING: The L-rod measures 10.5 mm in diameter, and the vertical down tube measures 7/8 inch in diameter. Your tom bracket and mounting receiver must accept these sizes. Please measure your existing hardware before purchasing. 10.5 MM L-ROD TOM CONNECTION: Designed specifically for tom drums with a mounting bracket that accepts a 10.5 mm rod. It will not fit brackets requiring a different rod diameter, including 9.5 mm, 12.7 mm, or brand-specific mounting systems. 7/8-INCH DOWN TUBE: The vertical tube installs into a compatible 7/8-inch receiver, rack clamp, multi-clamp, or bass-drum tom mount. The receiving clamp or stand is not included. ADJUSTABLE BALL-JOINT POSITIONING: The ball joint allows the tom angle and position to be adjusted, then securely tightened using the wing bolt for comfortable placement. CHROME-PLATED METAL CONSTRUCTION: Durable metal hardware with a polished chrome finish for drum-kit builds, replacement applications, rehearsals, studio use, and live performance.
