Sometimes a prefab fireplace decides it wants to be difficult. I’ve seen it more times than I can count—your Design Specialties aluminum prefab fireplace door is perfect, but the standard mounting hardware just won’t cooperate with your factory-built steel firebox. That’s exactly where this alternative mounting hardware kit earns its keep. 🔧
This kit is designed for those situations where the original brackets can’t quite reach, line up, or sit securely. The extension brackets allow you to mount the door by reaching all the way to the side walls of the firebox, where they can be properly screwed in and secured. Translation: a safer, sturdier install—and a lot less muttering under your breath.
✨ A quick real-world tip from me:
Before installing, make sure your fireplace door has the mounting stud on the back frame. If it doesn’t, no panic. You can drill into the back frame of the door and attach the bracket using self-tapping screws (not included). I’ve done this on stubborn installs, and once everything’s tightened down, it’s rock solid.
This kit is specifically designed to work best with Design Specialties zero-clearance / prefab aluminum fireplace doors, so you’re not guessing or improvising with mismatched hardware. It’s one of those behind-the-scenes pieces that doesn’t get much glory—but without it, your door simply isn’t going anywhere.
🔥 Why I recommend keeping this option in mind:
Prefab fireboxes aren’t always built the same, especially in older homes. Having an alternative mounting solution can save you time, frustration, and an unnecessary return. Nova usually leaves the room when installs get tense… this kit helps keep the peace. 🐾

Designed for Design Specialties aluminum prefab / zero-clearance fireplace doors
Door must have a mounting stud, or you’ll need to drill the back frame
Self-tapping screws are not included
Intended for factory-built steel fireboxes where standard hardware does not fit
If you’re close—but not quite there—before ordering additional hardware, there are a couple of tried-and-true alternatives I’ve used in the field more times than I can count:
✨ Longer drywall screws
Sometimes all you need is a bit more reach. Picking up longer drywall screws from your local hardware store can give you the extra bite needed to secure the bracket into the side wall of the firebox.
✨ Plumber’s tape + self-tapping screws
For trickier installs, strips of plumber’s tape can be shaped and used as a mounting extension, then secured with self-tapping screws. It’s not glamorous, but it’s effective—and surprisingly sturdy when done correctly.
🔥 My honest advice:
If these solutions feel even slightly questionable for your setup, the alternative mounting hardware kit is still the cleanest and most secure long-term option—especially for factory-built steel fireboxes that refuse to play nice.
