The ProTeam 103393 is a complete two-piece backplate and harness assembly that restores the carrying comfort and load balance of a Sierra or Lil Hummer backpack vacuum. When the original harness webbing frays, the buckles wear out, or the backplate cracks, this genuine OEM replacement gets the machine back to all-day wearability instead of forcing an early replacement of the whole unit.
Built for
This assembly is ideal for facility managers, janitorial contractors, and building-service crews who run ProTeam backpacks through long daily shifts. Common reasons to replace the harness include worn or torn shoulder padding, a broken waist-belt or sternum buckle, and a damaged backplate that no longer distributes weight evenly. The redesigned harness improves comfort for operators who vacuum stairwells, large carpeted floors, and hard-to-reach areas for hours at a time.

It is designed for the ProTeam Sierra and Lil Hummer backpack vacuum platforms. Confirm your model before ordering if you are unsure.
