PRODUCT DESCRIPTION
Dual Line Balcony Railing
Dual Line is a geometric steel balcony railing built around layered square lines. As a result, the design creates depth and visual movement while maintaining a clean architectural profile.
The compact perimeter keeps the composition visually controlled. At the same time, the repeating square pattern gives the railing a distinctive identity within the AMP Classic Railing Collection.
Dual Line Design
Layered geometry inside a compact steel frame
Dual Line uses 1/2″ solid square steel bar to create its repeating geometric pattern. Because the square lines overlap visually, the design develops depth without appearing excessively heavy.
In addition, a 1″ tubular steel perimeter creates a compact architectural boundary. Therefore, the geometric infill remains the primary visual feature.
AMP manufactures each railing according to the selected project dimensions and finish. Consequently, the final assembly can coordinate more closely with the architectural opening.

Custom Fabrication
Built to your project dimensions — not adapted from a one-size-fits-all railing.
Standard dimensions provide a practical starting point. However, they do not define the manufacturing limits of Dual Line.
Instead, AMP can coordinate custom length, height and projection when a project requires different dimensions.
How Dual Line Is Manufactured
1. Compact Tubular Frame
First, AMP cuts and squares the 1″ tubular steel perimeter. Then, our fabrication team welds the components together to establish the final outside geometry.
As a result, the frame creates a clean and consistent boundary around the decorative infill.
2. Layered Square-Bar Pattern
Next, AMP cuts the 1/2″ solid square steel bars according to the required pattern. Afterward, the fabrication team positions the individual components to create the repeating Dual Line geometry.
Once the alignment is confirmed, AMP joins the pattern to the perimeter frame.
3. Surface Preparation and Finish
Finally, AMP prepares the welds and exposed steel surfaces for the selected exterior finish. Therefore, the completed frame and geometric pattern read as one coordinated architectural assembly.

Available Sizes
Standard Lengths
36″ · 42″ · 48″ · 54″ · 60″ · 72″ · 84″ · 96″
Available Heights
18″ · 24″ · 30″ · 36″ · 42″
However, AMP offers the 18″, 24″ and 30″ configurations strictly for architectural and decorative applications. Therefore, the project team must verify the suitability of any height before using the railing in a code-regulated application.
Projection
8″ Standard · Custom Projection Available
The standard projection is 8″. However, this dimension does not limit the design. AMP can manufacture a different projection when the architectural opening or project conditions require one.
Custom Dimensions
Need a different length, height or projection? In that case, AMP can review the project requirements and manufacture a custom configuration for the architectural opening.
Product Use Notice
Decorative Heights — 18″, 24″ & 30″
AMP manufactures these height configurations strictly for decorative and architectural accent applications.
Not a Safety-Rated Guard
The 18″, 24″ and 30″ height options do not serve as guardrails, balcony guards, pool barriers, fall-protection systems or other life-safety systems.
Intended Use
Therefore, use decorative-height products only as architectural accents. Do not represent or install these configurations as structural safety barriers.
Project Verification
In addition, the buyer, contractor, installer or design professional must confirm the intended application, structural attachment, required loads and opening limitations.
Furthermore, the responsible project professional must review applicable federal, state and local requirements before installation.
Custom Dual Line Configurations
Standard sizes simplify product selection. However, AMP can manufacture Dual Line for project-specific dimensions when necessary.
For example, a project may require a different projection to coordinate with façade depth or surrounding architectural elements.
Additionally, AMP can review variations in length and height when the architectural opening requires a different configuration.
Finish Options
Dual Line is available in four architectural finishes.

Project Requirements
Final railing height, opening limitations and structural loads depend on the intended application. In addition, the project team must consider the mounting method, substrate and attachment requirements.
Therefore, the responsible contractor, installer or design professional should evaluate each code-regulated application for the specific project before fabrication and installation.

PRODUCT USE NOTICE — DECORATIVE HEIGHTS (18″, 24″, 30″)
The 18″, 24″, and 30″ height options of this model are designed and manufactured strictly for decorative and architectural accent purposes. These dimensions do not meet, and are not intended to meet, applicable U.S. building code requirements for guardrails, balcony railings, pool barriers, or any other fall-protection or life-safety application.
These products must not be installed, modified, or represented as a structural balcony, guardrail, safety barrier, or load-bearing component under any circumstance. They are not designed to withstand human weight, lateral force, or impact loads associated with safety-rated railing systems.
It is the sole responsibility of the buyer, installer, contractor, or end user to determine the suitability of this product for its intended application, to verify compliance with all applicable federal, state, and local building codes prior to installation, and to install the product into adequate structural backing in accordance with standard construction practices.
AMP — Architectural Metal Products expressly disclaims any liability for injury, property damage, or code violation arising from the use, modification, or installation of this product in a manner inconsistent with its intended decorative purpose.
