MG-150 Unclipped Mullions

The MG-150 Unclipped mullion supports spans up to 120 inches at 120 psf design pressure without a through-frame clip, and the configuration is rated up to +150/-150 psf. That makes it a strong connector for tall, ganged impact assemblies. We confirm the design pressure your specific opening requires before specifying the mullion.

Yes. The MG-150 Unclipped mullion is an aluminum extrusion certified for High-Velocity Hurricane Zone installations and is large-missile impact (LMI) rated. It carries Florida Product Approval FL40673.R3. We'll confirm that approval covers your ganged configuration when we quote the project.

The MG-150 Unclipped joins ganged units without a through-frame clip, while the clipped variant uses positive through-frame clipping. Which one we use depends on the project's structural engineering and the spans involved; the unclipped version handles spans up to 120 inches at 120 psf without that clip. We'll determine the right variant for your assembly based on the opening's requirements.

Yes. It uses the same powder-coated aluminum finish system as the rest of the Mr Glass line, with AAMA 2604 standard (5-year warranty) or upgraded AAMA 2605 (10-year warranty). That lets the connector between your ganged units match the frames of the windows and doors it joins. We match the finish across the full assembly so the opening reads as one unit.

The MG-150 Unclipped is a structural component that's specified when we combine multiple impact windows or doors into one larger opening, so it's part of that assembly rather than something you'd order on its own. Because cost depends on the overall configuration, how many units are being ganged, and the opening, Armor Pro provides a free estimate with any required mullions folded into the total installed price.

Mr Glass runs a deep catalog, and we install across most of it. On the residential side that means impact windows in single-hung, horizontal-roller (sliding), fixed picture, and casement and awning styles, plus a full range of doors: entry and outswing doors, architectural pivot doors, and sliding glass doors including the multitrack pocket slider. They also build a commercial line of impact and non-impact storefronts, window walls, curtain walls, glass railings, and aluminum louvers that we handle on light-commercial projects. We help you match the right Mr Glass product to each opening and pull the matching approval for your county.

Most of the line is, but it depends on the specific product. Mr Glass's premium residential windows are dual-certified to both Large Missile Impact (LMI) and Small Missile Impact (SMI), which covers them for high-rise and coastal work anywhere in the High-Velocity Hurricane Zone of Miami-Dade and Broward. Their value-tier windows and all of their doors carry the impact certification needed for the HVHZ as well, and a couple of commercial products (the MG-275 door and MG-4500 storefront) are non-impact and are not used in the wind-borne-debris zone. We confirm the exact product, rating, and approval for your address before we quote and permit.

Curtain wall, storefront, window-wall, and related framing systems for commercial and multi-family buildings, including impact-rated assemblies for the High-Velocity Hurricane Zone. These are engineered, project-specific systems rather than off-the-shelf units.
