It excels in compactness (11-inch folded profile) and affordability ($1,499 base price) and is specifically marketed for 'exceptionally narrow staircases.' However, it does NOT meet the buyer's strict specification of 'under 30 inches' without case-by-case verification. The manufacturer explicitly recommends the product only for staircases 36 inches or wider under standard conditions, requiring custom measurement for anything narrower. Additionally, conflicting information about installation (self-install vs. professional-only) and warranty terms (2-year vs. 5-year drivetrain) creates decision uncertainty. For homeowners with confirmed staircases between 30-36 inches, or for those willing to undergo the measurement verification process, Rave 2 is a strong contender. For those with confirmed staircases under 30 inches or those requiring maximum foot traffic preservation, a verification call to AmeriGlide (1-800-790-1635) is mandatory before purchase.","fit_assessment":{"best_considered_for":["Staircases 36+ inches wide where compact design and minimal obstruction are priorities","Homeowners willing to accommodate one-at-a-time stair usage with 11-inch folded clearance","Budget-conscious buyers seeking factory-direct pricing with self-installation options","Installations where stair-mounted tracks (rather than wall-mounted) are preferred"],"direct_answer":"AmeriGlide Rave 2 is a good fit for homeowners with narrow staircases under 30 inches, offering a compact folded profile of approximately 11 inches and a track footprint of 11.5 inches.
