PNLTB Series · Economical Rigid Panel Barriers

Q-PANEL® Top Beam Systems

Q-PANEL Top Beam systems provide a strong, professional alternative to traditional retractable-belt barriers. Built with heavy-gauge aluminum beams, they create rigid, durable queue lines that offer greater structure, visibility, and control in busy public and commercial environments. Within the Q-PANEL product ecosystem, the Top Beam system bridges the gap between the flexibility of a belt barrier and the substantial presence of a traditional Q-PANEL system. An optional panel, secured with grommets, helps prevent guests from ducking beneath the barrier while providing valuable space for branding, directional information, safety notices, or promotional messaging.

PRODUCT FEATURES

Why Choose the Q-PANEL® Top Beam?

Q-PANEL Top Beam delivers a more substantial boundary than a retractable belt without the cost or weight of a fully framed panel. The heavy aluminum top beam protects the insert, adjustable EZ-Off End Blocks simplify installation, and four top screws permit insert replacement while the system remains attached to its posts.

RIGID QUEUE CONTROL FOR TIGHTER BUDGETS

The Most Economical Q-PANEL Configuration

Top Beam concentrates the heavy-gauge aluminum at the upper edge of the insert, reducing frame material and weight while retaining the rigid panel surface needed for queue definition and communication.

  • Smallest standard panel weighs 10 pounds
  • Lightweight and easy to install

Frequently Asked Questions

What is a Q-PANEL Top Beam?⌄

It is an economical rigid queue panel that uses a heavy-gauge aluminum top beam and replaceable insert between compatible single-line RETRACTA-BELT posts.

How does Top Beam differ from a fully framed Q-PANEL?⌄

Top Beam concentrates the aluminum frame at the upper edge, reducing weight, material and cost. Fully framed Q-PANELS provide stronger perimeter framing, broader attachment configurations and additional size or privacy options.

Which posts work with Top Beam?⌄

Q-PANEL Top Beam is designed for compatible single-line RETRACTA-BELT posts. It does not require or use dual-line posts.

Are posts included?⌄

No. Posts and bases are sold separately. Top Beam panels can be added to compatible existing single-line posts or specified with new posts as a complete system.

Choose 48-, 72-, or 94-inch widths with either a 24- or 32-inch panel height. Custom sizes are available subject to requirements and minimums.

How is the insert changed?⌄

Which insert materials are available?⌄

Standard choices include 1/4-inch Black or White Sintra, clear or frosted acrylic, and 1/8-inch Black or White Durabond. Other approved materials and thicknesses may be available.

Are EZ-Off End Blocks included?⌄

Yes. Adjustable flexible EZ-Off End Blocks are standard and support installation and removal from compatible single-line posts.

Are support bungees required?⌄

Bungees are optional but recommended where the bottom of the panel needs additional rigidity or movement control.

Can Top Beam be used outdoors?⌄
