When you buy a "QLX" stand, you just don't buy any "X" stand, you invest in a system ! This system can be configured in a variety of ways to fit any keyboard players' needs. The QLX-3 is part of a complete line of options that are available for the "QLX" series as well as any Quik-Lok single-tier "X" stand with a "QL" prefix. A new, strong, non-slip, lightweight aluminum alloy locking collar called the "Grip-Lok 30" is used to anchor the QLX-3 to the main stand. The QLX-4 Mic boom and/or QLX-5 sheet music holder can also be piggy-backed on to the QLX-3.
