Aluminum Sub-Prole | English
G. Overlap Installation: If the top landing is greater than 8 feet across, the installation
will require an overlap molding which will allow the top landing to have expansion at the
stairs.
1. Prior to installing the last riser, install the aluminum sub-prole so that the track-side is on
the landing and the wide side of the base is installed on the existing riser where it will be both
adhered and screwed into place (9).
2. Cutting the assembled riser will require tting the riser so the tongue side of the assembled
riser is installed over the ridge of the sub-prole and pointing up to the landing. Once the
assembled riser is tted, apply glue to the back of it and install.
3. Cut the lncizo 5 in 1 to length. Cut the reducer side of the 5 in 1 o to make a square nose
transition molding (18).
4. Apply adhesive to the 5 in 1 so no adhesive lls the expansion and contraction area when
installed. This will allow the 5 in 1 stair nose to be pressed rmly into the aluminum sub-prole
track and allow the landing oor to have room for expansion and contraction. This will result in
an overlap nish of the landing ooring (17).
H. Finishing the installation
1. Make sure to wipe away all excess adhesive squeezed out of the joints.
2. Do not walk on the installation until after the drying time recommended by the adhesive.
3. Remove all tape and clean away any residual adhesive.
