move on to our stairs by taking a measurement at the very bottom and then correlating that measurement to the very top I can guarantee myself that the center slot on both of these posts are going to line up perfectly one element that you do have to be aware of when installing this system is that I'm having to use a corner post at this location because it's going into a 90° angle once it gets from the stair to the side of the house on this side and that means I'm having to use this larger post bracket which kicks everything out slightly if I didn't do a picture frame deck I highly doubt that anyone even notice this discrepancy but I did want to make sure that people were aware of this but I also want to suggest that if you do want a picture frame deck while also still utilizing this system you could always go with a wider board around the perimeter which would make this railing kick out much less visible in all honesty I am very nitpicky about stuff like this but now knowing how everything looks in the end I barely even notice it and I actually know of this circumstance versus people that have no idea about it which are much less likely to notice it we can finally move on to our final two posts which are stare end posts these are very similar to the end post that we previously installed but they are angled slightly at the very top of this post once the fasting location is determined I then pre-draw our holes install our fastners and our cover plate and move on to the next side where we can install our final post with that last one fully installed we can focus our efforts now on our cable rail which is the real star
