Superior WRT3042 Fireplace Doors — Exact-Fit Doors (WCT3042 Too)
Fireplace Doors for the Superior WRT3042
The WRT3042 and WCT3042 make up the 42-inch tier of Superior's current 3000-series wood-burning fireplaces, and the factory drawing gives them a generous front opening: 42 inches wide by 24 inches tall. That extra height matters when you shop for doors. Most 42-inch prefab doors on the market are built around the old 21-inch-class openings of legacy builder boxes; the 3042 stands three inches taller, and a door that ignores those three inches will either gap at the top or not mount at all.
Confirm the model — and mind the generations
The rating plate inside the firebox carries the full model string, WRT3042 or WCT3042 plus configuration suffixes; the two versions share one spec sheet and one opening. The generational trap is real here too: Superior and its Lennox-era siblings built many 42-inch wood fireplaces — the BR-42, BC-42, RD-42, and HC-42 among them — with openings documented separately from this one. A straight-on photo through our AI Fireplace Expert places yours in the right family in seconds.
Factory bi-fold or built to your numbers
- Superior's BD42 bi-fold is the factory accessory for this series — one style, one finish family.
- A made-to-order door is built to your measured opening and opens the rest of the design space: cabinet and full-view styles, finish choices, glass and mesh options, all configured with instant pricing in the prefab door collection.
- Either way, prefab-safe rules hold. Inside-fit mounting, unmodified firebox, unblocked air paths — the 3042's zero-clearance listing depends on all three.
Measuring your WRT3042
Width at three points, height at three points, with the smallest figures governing the build. The complete walkthrough is in our measuring guide. Facing stone, tile returns, and hearth decisions all meet the firebox differently — the factory's 42 x 24 is the starting point, and your tape measure has the final word under the Perfect Fit Guarantee.
What NOT to do with a WRT3042 door
| Don't | Why |
|---|---|
| Buy a door sized for legacy 42-inch Superiors | Older 42-inch models use shorter openings. The 3042's 24-inch height is its own spec. |
| Burn wood with tempered-glass doors closed | Closed-door firing can shatter tempered glass — it is rated for doors-open use. |
| Clamp a masonry overlap door onto the face | Sheet-metal zero-clearance construction offers no safe anchor for masonry hardware. |
| Order from framing dimensions | The framing spec serves the carpenter. The door serves the 42 x 24 front opening — as measured. |
