Installation Guide
Step 1: Measure the distance between posts and cut the rails to 
size. For even spacing between the balusters and posts, be sure to 
cut from both ends of rails.
Step 2: Place the moulded cap rail upside down on a flat surface. 
Next, place one of the 2x4 rails into the moulded cap rail channel 
so that the holes are facing up. Starting from either end, fasten the 
top 2x4 to the cap rail using the (9) 3" screws through holes 1, 2, 5, 
8, 11, 14, 17, 19 and 20. If rails are trimmed, predrill any additional 
holes with a 1/8" drill bit and insert the screw into the next nearest 
hole. (Fig. 1)
Step 3: Attach two support blocks on the bottom of the bottom 
2x4 rail using 4” screws. The support blocks install under holes 7 
and 14. If your rail was trimmed, divide the overall length by three 
to determine support block spacing and install under the holes 
closest to this measurement. If the holes have not been predrilled, 
predrill with a 1/8” drill bit. (Fig. 1)
Step 4: Attach the (4) 2x4 railing brackets to the posts according 
to the included instructions.
Step 5: Attach the bottom 2x4 rail, with the holes facing up, using 
the 2x4 railing brackets. Insert the balusters into the predrilled 
holes. (Fig. 2)
Step 6: Attach the cap rail by aligning the holes to the baluster at one 
end of the rail and working your way to the opposite end, ensuring 
that all of the balusters are secured between the two rails. (Fig. 2)
