4 x 4 Instructions
Quickporch is a unique deck system. The order of assembly may seem odd, but it will assure the best results. Therefore, the perimeter will be suspended and assembled level with temporary props before anything else is attached to it.
Preparing to build your deck
Read all instructions
BEFORE starting the project.
TOOLS NEEDED: Power driver with tips (including #2 square drive and 5/16” lag driver), saw (hand or power), level, tape measure, any square, and a shovel and tamping bar.
CLEAR all obstacles from the area where you intend to put the deck. Place the platform on the ground where you want the deck to sit. Determine which of the three-(3) stair options will work best for your application. Configuration 1 and 2 will require only one handrail on the stair while configuration 3 will require the second handrail kit, which includes a fourth long post. Configuration 3 cannot be used with a 46” x 69” deck.
MEASURE AND MARK. Your platform is 46” x 46” or 46”x 69”. Use a tape measure to mark the house where the deck will begin and end. Also mark the desired height of the deck at both ends or mark one end and use a level to determine the other mark. This height may be from 1/2” to 7 3/4” below the door depending on the door swing and local codes.
ASSEMBLY DETAIL INSTRUCTIONS FOR PLATFORM
Choose the configuration you need and place the deck so that the correct side will be toward the house. By rotating the 4x4 platform 90 degrees you can change from configuration #1 to configuration #2. In the case of a 4x6 platform, to change from configuration #1 to #2 it is necessary to remove the piece of decking that has one notch for the 3rd post and flip it end for end and reinstall it.
Temporarily attach 2 – 2 1/2” screws 5 1/2” below where you want the top of your deck. Set the back of your platform on these screws and level from front to back. It is necessary to use some kind of temporary support to maintain the set height from the platform. A 2x2 with a screw in it or a stack of blocks will do
as long as the platform is kept level. See fig 1. Now that you have the platform temporarily in place, you will have to assess what the posts will sit on. If all your posts are on concrete, asphalt, or any hard surface, go on to the next step.
If the posts are on grass or dirt, then dig in some sort of block (tamp hole with tamping bar or post to settle it before placing block in it) directly below the corners of the deck. Check your local building codes to determine what types of blocks may be used. Here are some possibilities 1) concrete blocks, 2) treated wood blocks, 3) “Bell” or pre-cast blocks, or 4) poured cement and metal post bases.
There will be a long post in three corners for configuration 1 and 2, or a long post in each corner for configuration 3 (4x4 only). Measure the distance of each post accordingly. *See note below. Then cut each post to its corresponding length. See fig 2. Put the long posts In place and attach with the 4” lag screws with washers through the sides of the platform. When cutting the under deck posts (short post), measure the distance from the top of the platform to the ground and subtract 1 3/8” to allow for the top of the post to sit underneath the decking of the platform. Attach the short post with lag screws.
If a platform requires four long posts for configuration 3, cut a hole in the last corner of the deck. Cut a hole by removing the last deck board and cutting a 3 3/4” x 3 3/4” notch in the board and replace it on the deck. Once the posts are in place, remove the leveling stick.
RAILING. Place tow of the 4” x 4” cut offs on the decking at either end of the opening and set the guardrail on them to ensure proper spacing from the deck at both ends of the rail. See fig 3. The inset of the rail to the posts is up to the installer. The 4” lag screw attach through the baluster of each rail into the post, and they should not be left too far out past the edge of the 4” x 4” post.
BRACES. There are two braces for each corner post (a “right” and a “left”). Lay each set out ahead of time to get the “prettier” ones to the front. Use 4 – 2 1/2” screws on each brace. Place each brace flush with the outside of the post and inside the platform. See fig 3.
POST CAPS. Center the 4” x 4” post and attach with 2 1/4” screw.
Now your ready to build your stair. See adjustable Stair Instructions.
*If provided, add spacers to the bottom of the posts with 4 #10x1 – 1/4” screws.
