Frequently Asked Questions

The ECO Clipped Aluminum Tube Mullion is a piece of mulling hardware that joins two or more impact units into a single, structurally-tied assembly, such as a wide picture-window-and-door combination or a multi-window ribbon. It is a spec-only commercial component from ECO's Eco-Guard Specialty & Commercial Components group, so it does not have its own public product page and shows up only in the engineering package for a job. When your opening is too wide for one unit, we install this mullion to tie the units together so the whole assembly carries its wind load as one.

Yes. The Clipped Aluminum Tube Mullion is HVHZ-approved and carries a Large Missile Impact (LMI) rating, so we can use it on impact assemblies permitted inside the Miami-Dade and Broward High-Velocity Hurricane Zone. It runs on Florida Product Approval FL41740 (current revision FL41740.R2). We confirm the approval and the matching units on your job's engineering before we permit.

The Clipped Aluminum Tube Mullion is rated to a design pressure of +120/-120 psf, and the approval covers a mullion up to 144 inches tall by 72 inches wide. The design pressure your assembly actually has to meet depends on the opening size, the building height, and the wind zone, so we verify the required rating against your engineering at quote. We'll confirm the mullion and the units it joins are matched to your opening before we order.

The mullion is an aluminum component, and ECO offers its standard range of frame colors and finishes across the Eco-Guard line, so we coordinate the mullion finish to match the impact units it joins for a clean, consistent look. Because it is a spec-only part rather than a stand-alone product, the finish is selected as part of the overall assembly. We'll confirm the available finishes and match them to your windows at quote.

All three are spec-only Eco-Guard Specialty & Commercial Components, but they do different jobs: the Clipped Aluminum Tube Mullion (FL41740) joins multiple impact units into one assembly, the Series 2700 Aluminum Louver (FL33717) screens mechanical equipment, and the Series 1000 Aluminum & Glass Railing handles guardrails. The mullion is the only one of the three carried under a statewide Florida Product Approval. We'll spec the right component for what your project needs.

Because the mullion is part of a larger combined impact assembly rather than a standalone product, the installed price depends on the size of the opening, the number and type of units being joined, the glass package on those units, and the condition of the opening. Armor Pro provides a free, no-obligation estimate that covers the units, the mullion hardware, and the installation. We'll measure your opening and confirm the engineering before we give you a firm number.

Beyond the marketed windows and doors, ECO holds Florida approvals for a set of architect- and engineer-spec components: the Series 2700 hurricane-rated aluminum louver, a clipped aluminum tube mullion for joining multiple units, and the Series 1000 aluminum-and-glass railing system. These don't have consumer product pages — they show up in job packages and commercial specifications. We install them when a project's drawings call for them.

A hurricane-rated louver is a fixed metal-blade screen that lets air pass to mechanical equipment — rooftop HVAC, generators, penthouse plant — while still resisting windborne debris, so the opening doesn't compromise the building envelope. ECO's Series 2700 is impact-rated for that role under Florida Product Approval FL33717. It's a commercial and equipment-screening item rather than something a typical home needs.

Yes. ECO's residential aluminum impact lines carry Miami-Dade Notices of Acceptance and Florida Product Approvals, which makes them eligible to install in the High-Velocity Hurricane Zone (Miami-Dade and Broward counties). The exact wind ratings depend on the specific series, size, and configuration, so we confirm the right product for your opening on the quote. We pull the permit and submit the approval documents as part of every job.
