Description
Minnesota-Made Adjustable Stair Tread Extender
This is the stair tool we reach for when clean edging and safety actually matter.
The Minnesota Tread Extender is a locally made, professional-grade stair extension designed to give hardwood floor edgers a stable, level platform on stairs. Instead of fighting narrow treads, uneven riser heights, or unstable wheel placement, this tool creates a solid support surface so the edger tracks smoothly and predictably.
The adjustable poplar and pine legs slide to fit most stair risers, while the hardwood plywood top provides exceptional rigidity with minimal flex. This keeps the edger stable under load and reduces chatter, tipping, and uneven cuts. The lightweight design is easy to move stair-to-stair while still protecting finished treads from dents or damage.
For contractors who do stair work regularly, this tool quickly becomes essential. It improves accuracy, reduces fatigue, and makes stair edging safer and faster.

Dustin’s Notes
Stairs are where edging gets sketchy fast. This takes the fight out of it. The edger tracks flat, the step stays protected, and the work gets cleaner with less effort.
