RCF FL-B HDL 20-18

RCF FL-B HDL 20-18 Flybar for Serious HDL 20-A Line Array Rigs

The RCF FL-B HDL 20-18 is the dedicated steel flybar engineered to fly up to 16 HDL 20-A active line array modules or stack them over HDL 18-AS subwoofers with confidence. Its black steel construction, CE-compliant safety design, and purpose-built geometry give system techs a clean, reliable frame for touring, rental, and fixed installations built around the HDL 20-A platform.

Each frame ships ready for the field with a stacking bar, pickup tab with shackle, and three rigging pins. That means fewer last-minute hardware hunts and faster builds when you need to flip between flown arrays and ground-stacked configurations in ballrooms, clubs, churches, and outdoor stages.

With a width of 733 mm (28.86 inches), depth of 676 mm (26.61 inches), and a working weight of 20.69 kg (45.61 lbs), the FL-B HDL 20-18 balances strength and handling, packing neatly into trucks while still delivering the rigidity needed for tall HDL 20-A arrays. For Chicago DJs, production houses, and regional sound companies, it anchors rigs that have to go up safely, sound big, and come down fast.

Real-world applications and sound roles:

• Regional festival and fairground HDL 20-A hangs using a single, dedicated RCF flybar.
• Ballroom wedding and corporate AV systems where clean sightlines and compact arrays matter.
• Club and theater installs that rely on fixed HDL 20-A clusters with certified hardware.
• Touring and cross-rental rigs that need standardized RCF HDL 20-A fly hardware.
• Church and house-of-worship HDL 20-A systems needing reliable, CE-compliant suspension.

Rigging Configurations for the RCF FL-B HDL 20-18 Flybar

The RCF FL-B HDL 20-18 is all about giving system techs predictable, repeatable rigging options for HDL 20-A and HDL 18-AS systems. While it has no electronic controls or DSP of its own, its included hardware defines clear ways to deploy your line arrays safely and efficiently when used within RCF’s official guidelines.

• Flown HDL 20-A Arrays: Use the FL-B HDL 20-18 as the top frame when flying up to 16 HDL 20-A modules within RCF’s published load and angle recommendations, giving you tall, even-coverage arrays for live music, DJ, and voice-heavy shows.
• HDL 18-AS Ground Stacks: Combine the flybar with the included stacking bar and HDL 18-AS subs to build ground-stacked systems with HDL 20-A modules on top, ideal where trim height is limited or flying is not possible.
• Central Pickup with Shackle: The supplied pickup tab with shackle provides a clean, central hookup point for rated motors or fixed points, helping riggers establish a consistent lift position show after show.
• Pinned HDL Connections: Three included pins interface with the HDL rigging system, creating secure connections between the flybar, HDL 20-A modules, and stacking hardware when used according to RCF rigging instructions.

In all cases, the FL-B HDL 20-18 should be deployed by qualified personnel following RCF’s official documentation, local regulations, and venue requirements for suspended loads.

Engineered Capacity for HDL 20-A Line Arrays

One of the defining strengths of the FL-B HDL 20-18 is its ability to handle up to 16 HDL 20-A modules on a single frame. That capacity gives system designers room to build arrays that truly match the coverage and SPL needs of the event instead of compromising on box count because of rigging limits.

• Build compact 4–8 box arrays for wedding ballrooms and corporate breakout rooms while keeping the same frame for larger shows.
• Scale up to 12–16 box hangs for outdoor stages, arenas, or long-throw environments that demand strong vertical coverage.
• Keep inventory simple by standardizing on one RCF flybar across multiple rigs and trucks.

Flexible Flying and Stacking Options

Designed as a flybar for HDL 20-A or HDL 18-AS, the FL-B HDL 20-18 gives you the flexibility to fly HDL 20-A as a full array or ground-stack it over HDL 18-AS subwoofers using the included stacking bar. That dual-role design helps crews adapt to different trim heights, room shapes, and rigging rules without swapping hardware.

• Fly full HDL 20-A arrays when the venue allows overhead suspension and you need maximum coverage and sightline control.
• Ground-stack HDL 20-A on HDL 18-AS when truss, lifts, or building structures are unavailable or impractical.
• Use the same frame from club installs to festivals, keeping your HDL 20-A rigs consistent and familiar to your techs.

Tour-Ready Steel Construction and Finish

The FL-B HDL 20-18 is built from steel and finished in black, pairing durability with a low-visibility appearance above the audience. Its 20.69 kg (45.61 lbs) frame provides the mass and rigidity needed for serious line arrays while still being manageable for crews working fast-paced changeovers.

Paired with CE-compliant design, the hardware is ready for everyday transport and deployment in rental, touring, and installation environments where reliability matters as much as sound quality.

Optimized for RCF HDL 20-A Workflows

Because it is designed specifically around HDL 20-A ACTIVE LINE ARRAY MODULES and HDL 18-AS subwoofers, the FL-B HDL 20-18 keeps rigging simple and repeatable. That tight integration is ideal for Chicago production teams, regional PA companies, and DJs who want RCF HDL 20-A systems to be fast to deploy, easy to scale, and consistent from venue to venue.

• No guessing which generic frame works with your HDL 20-A inventory; this is the dedicated RCF solution.
• Cleaner visual lines on stage thanks to a frame that matches the look and footprint of the HDL family.

How to Deploy the RCF FL-B HDL 20-18 in the Field

Deploying the FL-B HDL 20-18 safely means pairing its RCF-rated capacity with solid rigging practice. Always work with qualified personnel, follow RCF’s official documentation, and respect local regulations for suspended loads. Used correctly, this frame becomes the backbone of HDL 20-A systems for clubs, festivals, churches, and Chicago event halls.

• Verify structure and hardware: Confirm the building structure, truss, or lift is rated for the total array weight and that hoists, shackles, and slings meet or exceed the required load ratings.
• Prepare the frame: Inspect the FL-B HDL 20-18, stacking bar, pickup tab, and pins for any damage. Install the pickup tab with shackle according to RCF guidelines before lifting.
• Attach the first HDL 20-A module: Connect the top HDL 20-A cabinet to the flybar using the supplied pins, making sure all locking mechanisms are properly engaged.
• Build the array within spec: Add additional HDL 20-A modules, setting angles according to your design and staying within the maximum of 16 cabinets specified for the FL-B HDL 20-18.
• Configure ground stacks with HDL 18-AS: When stacking, use the included stacking bar with HDL 18-AS subwoofers as outlined in RCF documentation, then secure HDL 20-A modules on top.
• Final safety checks: Before lifting or energizing the system, confirm all pins are fully seated, shackles are closed, and no cabling or hardware is pinched or overloaded.

A correctly deployed FL-B HDL 20-18 turns HDL 20-A inventory into a scalable, professional line array system that is safe, repeatable, and ready for high-energy shows in Chicago and beyond.
