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. Pre-drill holes on
the metal insert with a 1/4" drill bit, aligning the center of the spindles to the center of the metal handrail 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 metal insert, begin to slide the spindles into place, aligning the pre-drilled holes. Starting with the center spindle, attach metal 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 cen-
tered 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. Screws should be snug; do not over tighten.
Slide the top rail onto the metal insert with attached spindles. This is intended to be a tight t; please use soap as a lubricant if needed.
To install the support block, take the 6" piece of metal insert, slide the support block into the prole of the insert, and secure with a premium
deck screw. Slide the insert to the center of the lower rail.
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.
