Installation Instructions

Starting with the post spindle set even with the end of the insert, continue down the top rail, evenly spacing spindles, making sure to meet local
building code for spacing. Keep in mind an additional post spindle is placed even with the opposite end of the insert.
On each end of the spindles, pre-drill the center, using a 1/8" drill bit to avoid splitting. The two post spindles will need to be pre-drilled to attach
the completed rail to the post sleeves. Using a 1/8" drill bit, drill three holes at a 60° angle in the spindle, spacing them 3-1/2" from the top and
bottom, and one on center.
All rail spans over 3' require a spindle support block centered under the lower rail assembly. Check with local building codes and cut the support
block to the required height from UltraDeck

spindles.
Taking the handrail insert, begin to slide the spindles into place, aligning the pre-drilled holes. Starting with the center spindle, attach handrail
insert and spindles using 3-1/2" premium deck screws. Attach post spindles ush on the two ends of the assembly. Remember spindles must be
centered to ensure ease of assembly when attaching the top rail. Do not use composite deck screws.
Position the lower rail so the spindles will rest on the top side of the rail. Secure the spindles to the rail from the underside using quality
3-1/2" premium deck screws. (Do not use composite deck screws)
Slide the top rail onto the handrail insert with attached spindles. From the underside of the handrail insert, attach the top rail using eight #4 3/4"
screws, equally spacing them along the handrail, using four on each side.
To install the support block, cut a 6" piece of handrail insert and slide the support block into the insert and secure with a premium deck screw.
Center handrail insert into the prole of the lower handrail.
Position the rail assembly between the post sleeves, following local building code height requirements. Secure the post spindles to the post
sleeves using six 3" composite deck screws through the pre-drilled holes.
Align the post caps with the top of the post sleeve and slide into place. A silicone adhesive may be used to secure the cap.
