Rogers new RDH7439-DBL Ultra-Matic Double Tom Mount is a modern redesign of the brand’s classic, bass drum-mounted original. For fast and exact placement, this new mount features a pair of Rogers hand-adjustable, Ultra-Matic 3/8” hex rod tom arms, both with independent rotation adjustment, built on a solid T-bar platform atop a 15” long 7/8” diameter down tube. Designed to be used with the RDH3249-BD, 7/8” Bass Drum Mounting bracket for precise mounting to a bass drum. As an original equipment upgrade, the oval plate design of the RDH3249-BD is the identical mounting hole pattern for most original Rogers bass drums that use the old-style Rogers oval plate, double tom mounts (366 “Londoner” Double Tom Holder or 365R “TopHat” Twin Tom Holder).
