Watts SpringFit APU-14 14" Access Panel — Radon Fan Service & Ceiling Cover

The 14" access panel for radon fan service, large cleanouts, and ceiling cutouts

When a radon fan lives above a finished ceiling — garage attic, basement bulkhead, mechanical room — you need access. Not just for the initial install, but for fan replacement 8–10 years from now when it stops moving air. The Watts SpringFit APU-14 is the 14×14" snap-in cover that makes that future service call a 60-second job instead of a drywall patch.

Why mitigators install one with every fan

• No cutting required — SpringFit clips grip the hole edge from inside; fits any rough cutout from 10" × 10" up to 15" × 15"
• Ceiling-rated — works on horizontal ceiling installs as well as vertical walls (no gravity sag like push-in friction fits)
• Paintable / wallpaperable — disappears into a finished ceiling after a coat of latex
• Future-proofs the install — fan replacement, system diagnostics, electrical service — all without cutting drywall

Common radon uses

• Above-ceiling RadonAway / Festa / Fantech fan service access
• Larger sub-slab inspection openings (multi-suction systems, commercial installs)
• Electrical junction box covers for fan-side wiring
• System retrofitting access — swapping fan model without re-finishing the ceiling
