Challenger DX77-FM Flush Mount Kit 70 Inch Rise
The Challenger DX77-FM is the factory-engineered recessed installation kit for the DX77 7,700 lb dual scissor lift (sold separately). It includes two precision-manufactured pit frames with integrated concrete tie points that are positioned before the concrete pour, securing the frames in place as the concrete cures without additional anchoring hardware.
Once installed, the platforms sit level with the shop floor when lowered, eliminating drive-over ramps and surface obstructions. The flush mount configuration delivers a 70" rise height for undercar clearance on passenger vehicles, light trucks, and SUVs.
The kit supports standard platform spacing of 21" to 27", with optional configurations for 36.8" spacing to accommodate wide electric vehicles and specialty applications. Designed and manufactured by Challenger Lifts in Louisville, Kentucky.
