Fasten the center baluster into the center slot using the two provided #8 x 1-1/4” screws. Work your way from one end of the top rail to the other by inserting balusters into the upper railing. Step 7: Attach Top Rail and Top Rail Cover Gentle tapping with a rubber mallet may make it easier to fasten securely.

Step 6: Install Remaining Balusters into Bottom Railįirmly insert remaining balusters into the lower rail holes. Note: Pre-drilling is required for attaching railing to bracket using a 9/64” drill bit. To ensure that you hit the bottom bracket tab, measure ½” from side of post and mark rail. Set the bottom rail into the bottom brackets (tabs on brackets will be inside of the bottom rail and not exposed).Īttach the bottom rail to the bottom bracket by fastening on top of rail into tab on bottom bracket using one provided self-tapping ⅝” screw on each side. Do not attempt to slide cover onto the rail from an end. Tip: Gentle tapping with a rubber mallet may help facilitate with snapping into place bottom rail cover.

Continue working your way down the length of the rail until complete. Starting from one side of the rail, begin snapping the cover onto the opposing slot. Align cover on one side of the bottom rail in slot on the side of rail. This will help ensure a gap on each end of the bottom rail for placement into brackets.

Tip: To prevent damaging the screw avoid using an impact driver Step 5: Attach Bottom Rail Cover and Bottom Rail to BracketsĪttach the “flat” bottom rail cover to the bottom rail by first centering the cover on bottom rail. Step 4: Attach Center Baluster to Bottom Rail (Post to Post)Īttach the shorter, center baluster in center slot in your bottom rail using two of the provided #8 x 1-1/4” screws. Mark and cut the top rail cover to be the same length as the top rail for all top rail configurations.

Next, slide the rail inserts out and cut ¾” from each side of insert before sliding back inside the rail and centering. Cut the top rail to the measurement between the top brackets (same dimensions as bottom rail). Mark and cut the bottom rail cover 1-1/2” shorter than bottom rail. Slide each rail insert out and cut ¾” from each side of insert before sliding back inside rail and centering. Cut the bottom rail to the measurement between the bottom brackets. Next, cut the bottom rail and bottom rail cover. Take this measurement and transfer it to your rails, ensuring the distance from the last baluster to each post is even.īefore cutting, ensure that the baluster holes on both the bottom and top rail align. Measure the distance from inside of the bracket to inside of bracket. Step 3: Cut Railings for Horizontal Brackets (Post to Post) Then, center the upper bracket on post above the marked line and attach using 3 self-tapping screws. Next, center the lower bracket on post above the marked line and attach using 2 self-tapping screws Then measure up from post base plate 33-7/16" for 36" rail height or 39-7/16" for 42" rail height. If you are not using the template, measure 1-3/8" from top of post base plate or 1-7/8" from decking surface. Tip: Use the Trex Signature rail templates to attach brackets (sold separately on ). Step 2b: Install Horizontal Fixed Brackets (Signature Posts) Tip: Use a clamp to help hold brackets in place while fastening with screws. Center upper bracket on post above marked line and attach using three 2" wood screws. Then, measure up from decking surface 33-15/16" for 36" rail height or 39-15/16" for 42" rail height. Center lower bracket on post above the marked line and attach using two 2" wood screws. Push skirt back onto decking surface before attaching bracket. Slide skirt up to allow for proper measurement. Measure 1-7/8" up from deck surface to bottom of bracket. (SKU: ALPOSTHWDECK) Step 2a: Install Horizontal Fixed Brackets (Pressure-Treated Posts and Posts Sleeves) Using post baseplate as a template, mark location of holes and drill through the decking and blocking with a ⅝” diameter drill bit (a longer drill bit will be required).Īttach posts using four ⅜” x 6” HG bolts, washers and nuts with the Trex aluminum backing plate underneath the blocking (acting as a large washer).

Install two 2” x 8” boards as blocking under post location using 24 pressure-treated compatible 3” wood screws. Install two 2” x 8” cross bracing frames between joists at 7-¼” using 12 pressure-treated compatible 3” wood screws. Trex Signature posts should be installed 6’ or 8’ CLEAR SPAN to account for appropriate railing length.
