Step Kits are designed for a standard 7/11 rise/run or a 32-1/2° angle. The following instructions and illustrations are
designed with the upper post support fastened 1-3/8" from the edge of the porch or deck surface and the lower post support fastened
1-3/8" from the foot of the steps. (See illustration in Step 1)
Step 1 - Prepare and install posts and decking. Prepare the posts and mounting surfaces to which the railing section will be attached.
A typical installation uses a 4" x 4" vinyl post sleeved over either a 4" x 4" treated wood post, or an LMT Blu-Mount with aluminum or
PVC guides. When using PRESIDIO
®
PVC Decking, the upper most 4" x 4" post (installed at the deck or landing surface) should
extend 38-1/2" above the wood joist framed structure for 36" high railing systems, and 44-1/2" above the wood joist framed structure
for 42" high railing systems. The remaining 4" x 4" staircase posts should be cut 7" longer to accommodate for the 7" stair riser. (See
illustration below). Cut and fasten the posts to the wood framing or if you are installing your PRESIDIO
®
guardrail system on a
concrete surface, install LMT Blu-Mounts to the concrete pad / staircase following the supplied Blu-Mount installation instructions .
Install decking boards over or around post supports. (Please refer to the decking installation instruction manual for the correct
installation procedures of the deck boards.) Sleeve the post supports with a 4" vinyl post. The installed post sleeves must be plumb for
correct installation of the rail section. If vinyl post skirts are being used at the base of the posts, slide the post skirts into position so that
they come to rest around the base of the 4" x 4" sleeved post.
Step 3 - Measure and cut the bottom rail. The bottom rail is identified by having two hollow cavities inside the rail. Measure the
distance between the base plates of opposing nylon post brackets keeping the tape measure 1" above the end of the step treads while
maintaining a 32-1/2° angle. If cutting of the bottom rail is necessary, cut an equal amount off both ends of the rail so to maintain
uniform baluster spacing between the posts. Loosely position the 2" x 3-1/2" bracket covers on opposing ends of the bottom rail.
Step 2 - Secure post mounting brackets.Attach the nylon post brackets to the sleeved posts by using the (4) #10 x 1-1/2" pan-head
screws for the 4" x 4" treated wood post, or the (4) #10 x 1" pan-head screws for the LMT Blu-Mount with aluminum or PVC guides.
Measure and secure the bottom nylon post brackets in accordance with the illustration provided in Step 1. Similarly secure the top
nylon post brackets to the sleeved 4" x 4" posts as illustrated.
