Riser Defi nitions
Riser Tailpiece (length of riser that extends down from cabinet bottom) - 
Dimension F on submittal drawing- Riser tailpiece sized for 2" (51) insertion into 3" (76) expanded section at top 
of cabinet. Actual job fi t may be 1" (25) to 3" (76) insertion (built-in +1" (25) fl oor to fl oor tolerance). Riser tailpiece 
should extend beneath bottom of slab a minimum of 5" (127) to facilitate brazing.
3" Expanded Section - Riser expanded at top of unit to accept a pipe diameter from unit above. (Top of riser 
always 3" (76) above top of unit.)
Floor to Floor Height (FF dim.) - Dimension from top of 
unit slab to top of slab above.
Slab Thickness (ST dim.) - Includes basic slab thickness 
plus any material added to slab prior to setting cabinets.
Clear Height (Top of unit slab to bottom of slab above) 
- This dimension is used to determine whether cabinet-
riser assembly will pivot through slab core without hitting 
bottom of slab above unit. If selected cabinet-riser will 
not pivot into position, special riser extension or shorter 
cabinet will have to be considered, (Clear height = fl oor 
to fl oor dimension less thickness of slab above unit.)
Room Riser Height (cabinet height + 3" (76) - Standard 
cabinet height (88"(2235)) + 3" (76) = 91" (2311) - 
Shorter than standard cabinet heights will have shorter 
room riser heights.
Maximum Riser Height - Maximum length is 115" (2921). 
Total Riser Height (dim. L on submittal) - Room riser 
(RRH) height + riser tailpiece length (F) = total riser 
length (115" (2921) max.).
Total Riser Height = Floor to Floor + 2" (51) 
(115" (2921) max.).
