The Genie 100778GT is a genuine OEM Mast Flap Clamp Plate built for Genie QS-series stock-picking mast lifts and GR-series Runabout vertical mast lifts. Sourced directly from Genie, this part matches the original specification for a direct installation without adaptation. It fits the QS-12R, QS-15R, QS-20R, QS-12W, QS-15W, QS-20W, GR-12, GR-15, and GR-20, making it the correct choice across a broad range of Genie vertical mast units. Cross-reference part number 100778GT against your machine's parts manual to confirm it is the right component for your serial number before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and material specifications, ensuring the plate seats and clamps correctly on the mast assembly.
- Direct-Fit Replacement — Designed as a drop-in replacement for the original Mast Flap Clamp Plate, preserving the correct clamping geometry without rework or modification.
- Broad Fitment Coverage — Compatible with Genie QS QuickStock mast lifts (QS-12R through QS-20W) and GR Runabout vertical mast lifts (GR-12, GR-15, GR-20).
- Mast Integrity — A correctly functioning clamp plate keeps the mast flap securely positioned during operation; a worn or damaged plate can allow unwanted movement that affects the smooth travel of the mast.
- Verified Part Number — Always confirm 100778GT against your Genie parts manual before ordering to ensure this is the correct plate for your specific unit and serial number range.
The Mast Flap Clamp Plate secures the flap element on the mast assembly of Genie vertical mast lifts, holding it in the correct position as the mast extends and retracts. When this plate is cracked, deformed, or missing, the flap can shift out of alignment, introducing unwanted play into the mast travel and reducing the smooth, controlled movement these machines depend on. Replacing a damaged plate with the correct OEM part restores proper clamp tension and mast alignment, keeping the lift operating as intended.
