Kirby Latch Assembly Bottom...
$6.99
Product details
This genuine OEM Kirby latch assembly bottom plate (Part #640689A) protects the underside of the machine and helps hold proper brush-roll height. It fits Gen 3 and a broad Kirby lineup, from the HERITAGE and LEGEND series through the SENTRIA and AVALIR models.
A cracked or warped bottom plate lets debris escape from beneath the machine and can throw off brush-roll contact with the carpet, reducing cleaning efficiency. Replacing the plate seals the underside again and returns the brush roll to its intended height.
- Fits: Kirby GEN 3, G4, G5, GSIX, HERITAGE I/II, HERITAGE II LEGEND, LEGEND II, SENTRIA, Sentria II, ULTIMATE G, DIAMOND EDITION, AVALIR, AVALIR 2, AVALIR PLATINUM
- Part: genuine OEM latch assembly bottom plate
- Benefit: protects the underside and maintains brush height
- Tip: replace when you see cracks, chips, or uneven brush contact
The plate installs as a direct-fit replacement using the existing latch points. Verify your Kirby model before ordering so the bottom plate seats correctly.
