Chapter 3: Getting Started
Lower Sash Track &
Threshold Installation for
Horizontal-Sliding Sashes
on 8', 10', 12', & 16' Floor-
Mounted Hoods
The lower sash track assembly is comprised of a sash
track threshold, front and rear ramps, and threshold
support brackets. With the corner posts removed the
sash track threshold should be placed on the floor
between the left and right corner posts, with their corner
posts removed at this time. Lay the threshold flat,
perpendicular to the hood liner walls. The sash track
threshold will extend to the hood sidetracks. Once the
sash track threshold has been placed in its final
position, check to be sure it is level. It must be level to
ensure proper movement of each of the door
assemblies. If the threshold is not level, place shim
material under it until it becomes level. Attach the sash
track threshold to the hood sidetracks with the threshold
support brackets and #10-24 hardware. Both front and
rear ramps are held in position without mechanical
fasteners and can be removed for easy cleaning, should
it be required. Simply place the flange of each ramp
assembly in the position as shown in the diagram below
for proper fit. The ramps are self-leveling to match
your existing floor conditions. The hood corner posts
should be installed prior to the placement of the front
sash ramp. See Figure 3-5.
