Quick answer: This is the genuine ResMed MicroFit™ forehead support dial (part 61289) — the small adjustment dial that fits into the forehead support bar on several Mirage masks and gives 24 incremental positions to fine-tune the forehead angle and mask fit with one hand. Turning it "dials in" the cushion against your face for a comfortable, leak-free seal without over-tightening the headgear. It fits the Mirage Quattro, Mirage Activa LT, Mirage Micro, Mirage Micro for Kids, and Mirage SoftGel. This is the dial only — not the forehead support bar or pad.
What's included
- 1 × ResMed Mirage MicroFit forehead support dial (part 61289)
Forehead support bar (61288) and forehead pad not included.
About this part
On Mirage masks with a MicroFit™ dial, the forehead support isn't fixed — you rotate a small dial to change the angle of the forehead support arm (and with it the cushion position on your nose). This is that dial:
- 24 individual adjustments — turn it clockwise or counter-clockwise for fine, incremental changes to the forehead angle.
- One-handed, tool-free — adjust the fit quickly, even while wearing the mask.
- Better seal, less tightening — dialing in the angle lets the cushion seat correctly against your facial structure, so you get a leak-free seal without cranking the headgear tight (which causes pressure marks and discomfort).
Over time the dial can crack, strip, or go missing (a common reason a Mirage mask stops holding its adjustment) — this genuine replacement restores the MicroFit adjustment.
Compatibility — and the two look-alike parts
Fits these Mirage masks: Mirage Quattro (full face), Mirage Activa LT, Mirage Micro, Mirage Micro for Kids, and Mirage SoftGel (nasal).
Don't confuse the three forehead parts (order the one you need):
- 61289 (this) — the MicroFit dial (the adjustment knob).
- 61288 — the forehead support bar (the arm the dial fits into) — for Mirage Quattro.
- Forehead pad — the soft cushion on the support (separate part).

Frequently asked questions
What does the dial do? It sets the angle of the mask's forehead support — 24 incremental positions — so you can fine-tune the fit and seal with one hand, without over-tightening the headgear.
Which masks does it fit? The Mirage Quattro, Mirage Activa LT, Mirage Micro, Mirage Micro for Kids, and Mirage SoftGel.
Is this the forehead support bar or the pad? Neither — this is just the dial. The forehead support bar (61288) and the forehead pad are separate parts.
Why would I need to replace it? Dials can crack, strip, or get lost, after which the mask won't hold its forehead adjustment. This genuine replacement restores it.
Do I need a prescription? No — this replacement part does not require a prescription.
Can I get it delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
