Frequently Asked Questions
The MG-150 Clipped is the clipped-anchor variant of Mr Glass's MG-150 structural mullion, an extruded aluminum member used to gang windows and doors together into a single combined assembly. It's specified when positive through-frame clipping is required to tie the units together. We use it on multi-unit openings where two or more impact windows or doors meet and need a structural connector between them.
Yes. The MG-150 Clipped 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 the approval covers your specific ganged configuration when we quote the job.
The MG-150 Clipped mullion is rated to +150 psf positive and -150 psf negative design pressure, which is a high structural rating for tying impact units together. It can span up to 120 inches in height. We verify the required design pressure for your opening and configuration before specifying the mullion.
The MG-150 Clipped is specifically the clipped-anchor version, which uses positive through-frame clipping to fasten the ganged units together, rather than a different anchoring method. It's chosen when the project's engineering calls for that clipped connection. We'll determine whether your assembly requires the clipped variant based on the opening's structural requirements.
Yes. The mullion 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 frame finish of the windows and doors it joins. We'll match the finish across the whole assembly so it looks like one cohesive opening.
The MG-150 Clipped is a structural component that comes into play when we combine multiple impact windows or doors into one larger opening, so it's specified as part of that assembly rather than as a standalone product you'd buy alone. Because pricing depends on the overall configuration, the number of units being ganged, and the opening, Armor Pro provides a free estimate that includes any required mullions in 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.
