- High to low floors
- Hardwood
- Sand and finish
The go-to when a thicker floor has to step down to a thinner one. Solid oak means you can stain it into a perfect match, but you pay for it with finishing work and a permanent nailed install.
Pros
- Solid red oak can be sanded, stained, and sealed to match any existing hardwood exactly
- The sloped 3/4 in profile ramps a taller wood floor safely down to a thinner vinyl or tile floor
- Multi-purpose profile also works as a threshold against a sliding-door track or masonry hearth
Cons
- Ships unfinished, so you must sand, stain, and topcoat it before install (extra time and dry-time)
- Real wood is not waterproof and will move seasonally, so it is wrong for wet areas
- Nail/adhesive install is more permanent and fussier than a snap-track piece
