RS70 Providence Rail System Installation Instructions 
RS70INST-1 (05/06/2019) 
f.  Ensure  rail  is  centered  on  face  of  newel  or  column  and  secure  each  end  with  two  rail 
attachment screws 🅑. 
g.  Drill a 3/16” hole down through the aluminum reinforcement and the Top Common Rail 
between the  first  and  second  baluster  at  both  ends  and  near  the  center  of  the  span (all  between 
balusters). Countersink holes from underside of the Top Common Rail for a #8 Screw to ensure that 
screw seats flush with PVC and to prevent stripping. 
h.  Apply a bead of latex caulk at the contact areas where the Rail Top Cap seats on the Top 
Common Rail. Seat the Rail Top Cap fully onto the Top Common Rail. 
Stair or Rake Rail Application 
Note: IBC code requires that finished stair rail heights be a minimum of 34" plumb off the nose of the 
tread.  The  standard  RS70  Providence  36"  rail  kit’s  balusters  will  typically  meet  these  requirements 
provided the rail is being installed with the bottom rail elevated above the stair treads. In the event that 
the railing is being installed directly at or slightly above the stair tread nose, INTEX recommends using 
the RS70 Providence Stair/Rake Rail kit, which will meet the minimum height requirement any scenario.  
1.   Determine angle, measure rail lengths and determine baluster layout/spacing 
a.  Ensure newels or columns to which rail will be mounted are plumb and sturdy enough to 
support  rail.  If  newel/column  covers  are  used,  ensure  they  have  blocking  at  each  location  where 
railing will be attached. 
b.  Determine and mark angle. 
c.  For standard baluster spacing (with the variable spaces at the ends of each rail section), 
use the pre-marked locations inside the Top and Bottom Common Rail. Determine best end spacing 
by either locating a baluster directly at the center of the rail section, or the mid-point between two 
balusters as the center of the rail section. Once Baluster spacing is determined, cut end(s) of Top 
and  Bottom  Common  Rail  to  angle  and  length.  Note:  do  not  cut  Rail  Top  Cap  until  section  is 
assembled and secured at all 4 mounting points. 
d.  If equal spacing between all balusters and newels/columns is desired, disregard Section 
c above and determine spacing based upon width and number of balusters (Note: check local building 
codes for maximum spacing allowed). 
2.   Assemble rail/baluster section. 
a.  Trim Balusters to required length and angle. 
b.  Using the decided upon spacing, at the center of the location for each Baluster, drill a 1/8” 
hole  through  the  Bottom  Common  Rail  at  the  centerline,  at  the  angle  of  the  Baluster  attachment. 
Repeat this for process for the Top Common Rail, using the same spacing. 
c.  Secure each baluster with one baluster screw 🅒 through the Top Common Rail, and one 
through the Bottom Common Rail. Ensure balusters are straight and aligned and secure with one 
baluster lock screw 🅓 through the bottom rail (offset from center) to prevent the baluster from rotating 
after installation.
