Light Weight Double Tom Stand. DW´s lightest weight tom stand, the 3900 features the same dual tom ball-and-socket/auxiliary clamp top as company´s popular 9900, but lighter gauge tubing makes it substantially more portable than its heavy-duty cousin. A sturdy double-braced tripod base still supports heavy rack toms, multiple cymbals and accessories. Auxiliary Clamp. Full-size heavy-duty 1 1/8" Double Braced Tripod Base. Hinged Memory Locks are included at tube joints to guarantee 100% repeatable, precise height settings every time.
