Rail sub kits have been pre-cut to 6ft. or 8ft. lengths. Check to ensure the kit is complete.
SAFETY: Always were goggles when cutting, drilling, and fastening materials.
NOTE: Check local building code requirements prior to installation.
IMPORTANT NOTE: 6" Top Rail is sold separately and comes in 12 and 16-foot lengths. Use the Top Rail Connectors with all joints including Post, In-Line, 450 and 22.50 to insure a proper fit between parts.
The 4"x4" and 6"x6" post sleeves have been designed to slide easily over the Composatron Tall Steel Surface Mount Bracket. Follow the Surface Mount Bracket instructions for wood deck or concrete slab before installation of the Post Sleeves. Pressure treated wood 4" x 4" or 6" x 6" can also be used but is not recommended due to uncontrolled swelling, cracking and twisting of the wood.
IMPORTANT: DETERMINING Post Height
4"x4" Center Post:
For 36" railing height, the post sleeve must be cut to 34".
For 42" railing height, the post sleeve must be cut to 40".
6"x6" Main Posts:
For other than column full height 6"x6" Post installations, cut the main 6"x6" Post Sleeve a minimum of 2" higher than the desired rail height or 38" for a 36" rail or 44" for
a 42" rail.
NOTE: If optional Post Skirt is to be used, install over Post Sleeve prior to installation of sub rail or use our 2 piece post skirt.
2. RAIL MEASURING AND CUTTING
Measure between post sleeves, top and bottom, to obtain the rail length. Also check rail opening to ensure the posts, newels or walls where the rail is to be mounted are plumb and square. To obtain proper baluster spacing, be sure to measure and cut retainer and bottom rail an equal distance from the center.
TIPS: See our web sight www.composatron.com for:
1) Optional cut technique to equally divide rail kits, i.e. make 2 rail sections from one rail kit and
2) How to cut and position railing on the Post Sleeve at a 45° angle.
3. RETAINERS AND BOTTOM RAIL BRACKET INSTALLATION (see Figure 3)
Place the U shaped end of the bracket on the under side of the bottom rail and retainer just slightly inside (1/16") the cut edge. Mark and drill pilot holes with a 3/16" drill bit. Drill holes to proper size using a 3/8" drill bit.
Note: When drilling the bottom rail, drill through the bottom wall only – Do not drill through the top
surface wall.
Using the Allen key supplied, screw the threaded insert into the 3/8" holes from the bottom until flush. Be careful not to over tighten/torque. Fasten brackets using the 1/4"x 20 pan head bolts to the underside of the retainer and bottom rail.
4. ASSEMBLE AND FASTEN
Align the ends of the baluster with the predrilled holes in the retainer (see fig. 4).
Using the #8 stainless steel wood screws, fasten the ends of the baluster to the retainer first, through the predrilled holes, then fasten the other ends of the balusters to the bottom rail (be careful not to over- tighten/torque the screws).
5. CENTER RAILING SUPPORT
Attach the stainless steel center support bracket to the Pre-cut center Support using the 1 remaining #8 wood screw. Install the support assembly in the
center of the underside of the bottom rail using the
1" screws supplied in the sub kit.
6. CONNECTION TO POSTS
#6-1: 4"x4" Center Post, Corner Post and 6"x6"
Main Posts
Center the assembled rail sub section between the post sleeves and position the bottom of the retainer aprox. 1/16" above the top of the 4x4 center post. Mark the bracket hole locations and drill with a 3/16" drill bit. Fasten the section to the post using the
#14 x 2" stainless steel painted screws supplied with a #3 Philips or square driver. NOTE: For the 4"x4" center post and corner post, the bottom of the retainer should sit at the top of the post to allow the top hand rail to pass over the 4"x4" center post. For
a center post corner application a 6" Top Rail Corner Connection Hardware Pack" is required.
#6-2: 6"x6" Main Posts, 45° Connection
Follow the 45° Rail Installation Instructions or visit our web site at www.composatron.com for details.
A 45° Hardware Pack is required for this installation.
7. INSTALL ALL SECTIONS
Before installing the top rail, insure all sub rail
sections are installed.
8. INSTALL 6" TOP HAND RAIL
After all sub rail sections have been installed, measure the length between the 6"x6" main posts and cut the Top Rail.
(NOTE: Use the System Connectors, sold separately, at all joint connections to insure proper fit). Place the cut Top Rail onto the retainer of the previously installed Sub Rails and over the 4"x4" center posts. (NOTE: If the Top Rail is tight over the 4"x4" Center Post, the retainers may be misaligned. To correct this problem, loosen the #14 x 2" stainless steel screws holding the top brackets, reinstall Top Rail and retighten the screws).
#8-1: Install Corner 6" Top Rail over Center Post
Follow the directions as per step #8. Cut Top Rails with corresponding 45° angles approximately 1/8" shorter than a piece for a tight fit to allow room for the joiner piece. Before installation of the Top rail, insert both Top Rails into the joiner. Place the loose assembled Top Rail pieces onto the retainer, find the proper seating location and firmly press Top Rails onto the retainers. (NOTE: Caulking may be used to seal the joiner to the Top Rail if desired). A 4"x4" Over-post Connection Hardware Pack is required for this application.
NOTE: Overpost Connections other than 90° are not possible with this rail system until our new 22 degree Post Sleeve and accessories become available. Please see separate Top Rail Connector printed installation instructions or visit our web site at www.composatron.com
9. FASTEN THE 6" TOP RAIL TO RETAINER
Use the remaining 1" stainless steel screws supplied, fasten up through the retainer into the underside of the Top Rail to lock it in place. Space screws evenly. For additional holding strength use caulking between the Retainer and the Top Rail.
1. PLACEMENT
Center the Surface Mount Bracket (SMB) at each post location and mark the mounting hole locations
on the surface. Position the open slot away from all fastening locations.
2. MOUNTING THE POST
Mark SMB mounting locations onto the deck surface.
• Concrete installation: Drill marked mounting locations with a 3/8 dia. Masonry bit to accept 3/8
dia. x 4” wedge anchors. Gently tap the anchors into the drilled holes.
• Wood Installation: There must be a solid base to fasten SMB to. A 5” min. thick blocking must
be securely fastened to the structure prior to installation of the SMB. DO NOT fasten the SMB
directly to the deck surface. The SMB is to be installed using 3/8”dia. x 5” lag bolts (the lag
bolts will require a 1/4” pilot hole to ensure the wood foundation blocking does not split).
3. FASTENING
Place the SMB over the mounting locations. Lightly tighten the mounting fasteners so that the SMB can
still move freely, but tight enough for the SMB to sit flush with the mounting surface.
Note: Wedge anchors are for concrete installation ONLY. For installation to wood surface refer to local building code.
(Recommended: Use minimum 3/8” x 5” lag bolts into solid wood mass underbody.)
4. SMB ADJUSTMENTS
If the SMB is out of plumb and or level, add shims to the base of the SMB.
Check for plumb and square. Repeat until correct.
5. INSTALL RAIL SECTION
• Cut the post sleeves to the desired length and slide them over the SMBs' squeezing the top of the
SMB to start the post sleeve and slide it down until flush with the base.
• Place assembled rail section between the posts and mark the bracket hole locations onto the post
sleeves as per the Railing Installation Guide supplied with the railing kit.
• *IMPORTANT: Remove the rail section and drill the bracket hole locations with a 7/32dia. drill
bit (*THIS DRILL SIZE IS CRITIACAL*). Drill through both the post sleeve and SMB.
• With all holes drilled, place rail section between posts and install as per the Railing Installation Guide.
6. FINAL STEP
With all rail sections installed, tighten all the SMB base fasteners. Install the 2 piece post skirts
supplied in the SMB kit (if you have purchased the SMB alone, you will need to purchase a 2 piece post
skirt to hide the base and fasteners).
• For Concrete installation: If the concrete anchors have tightened leaving the too much thread
exposed for the 2 piece post skirt to install properly, it may be necessary to cut the top of the
wedge anchor so it no longer interferes with the skirts snapping assembly).
