Heavy-duty, 3-leg, 5000 Series hi-hats feature lateral cymbal seat adjustment, integrated memory locks & 379 locking clutch. The uni-body Folding Footboard stays attached to the base casting when secured in the folded position. DW's patented Delta Ball-Bearing Hinge is a state-of-the-art lightweight aluminum design that incorporates ball bearings at both sides. The unique Bearing Link Connector, which connects the footboard chain to the pull rod, for reduced friction and increased sensitivity. Hinged Memory Locks are included at tube joints to guarantee 100% repeatable, precise height settings every time. The Lateral Cymbal Seat is a first in hi-hat design, allowing instant access for adjusting the bottom cymbal angle; a small detail that makes a big difference. The SM379 Locking Clutch comes standard & allows you to dial in closed "sloshyness" and lock it so it doesn't come loose. Upper Rods come standard in 2 lengths (21" & 15"), allowing you to customize the Hi-Hat Stand for your specific needs. Swivel Legs allow easy positioning of bass drum pedals & other stands around the Hi-Hat Stand. 1" upper tube. 1 1/8" base tube.
