The 8079 False Tread Kit is intended as an economical substitute for standard 8070 Treads and 8075 Risers when a carpet runner
is being used on a stair. The guidelines below will help the carpenter prepare the rough stair and install the False Treads and Risers.
We recommend the use of screws, whenever possible, and glue on all contact surfaces.

IMPORTANT: Please read these instructions completely before beginning installation!
PART 1 -- BUILDING THE ROUGH STAIR
1. Lay out the three stringers to the required rise and run
(C and B respectively). Accuracy is important for ease
ofttingthefalsetreadsandriserslater.(See Figure 1.)
NOTE: If using the 8010-2 False Starting Step,
see Part 5 before cutting the stringers.
2. Allowingspaceagainstthestudwallfordrywallandanished
skirtboard, space the stringers equally and secure the top and
bottom into place. (See Figure 1 and Figure 2 page 2.)
3. Cut the subriser to the overall width of the stringers and install.
(See Figure 1.)
NOTE: Always install all of the risers before any treads.
4. Using Figure 1 and the steps below, prepare the subtreads.
A= The overall rough stair width.
B= The rough stair run.
C= The rough stair rise.
D= 1-1/4" nosing to keep carpet even with the nosing on false ends.
E= Notch the closed end of the subtread 1-1/4" deep and 6" wide for the false ends.
F= Notch the open end of the subtread 1-1/4" deep and 6" wide for the false ends. NOTE: Subtract drywall and nished
skirtboard thickness from the 6" width.
If using 2x12’s for the subtreads, chamfer the bottom edge of D in Figure 1.
Install subtreads using screws and construction adhesive to reduce the chance of a squeaky stair.
5. Installthenishedskirtboardontheclosedsideofthestair.(See Figure 2 page 2, if applicable.)
6. Whencuttingouttheopensidenishedskirtboard,mitercuteachriseat45º(See Figure 2 page 2) to avoid
exposingendgrainonthefalseriser.Installthenishedskirtboard.(See Figure 2 page 2, if applicable.)
