Answers

there are several way you could do it. if for instance the landing is set off the ground where your bracket is set directly on the slab but since the landing is higher you can bolt the post into the side of the landing giving the post two point to anchor to the closer you are to the ground more than likely it will be wobbly

if you are using these brackets for the use of securing these posts in the pictures it would work because you have two anchoring points. the post against the house can also be secured into the houses siding etc. the bottom post at the first step you could use this bracket but you would also want to secure it into the riser brick. this bracket is not like using a CBS44 where it would be set into a footing. what you may want to use for these two posts is called ABU44. its has a taller sides with more surface to anchor to.

Is there a skirt that can go over this and hide it?

Asked by drew March 6, 2018

Answers

you can hide the bottom of this bracket but you will find that the fasteners and the bracket stem protrudes out a little more than the 4 x 4. one way is to measure the base bracket from the sides and include the heads of the fasteners in your measurement. . there will be a gap at the top of the base trim because you did this. now you could either caulk it of what I do sometimes is use another piece of trim whether I made it or purchased it like qtr. round or made a piece from the same material the base or post is made up from

for me its always been what am I anchoring to. if its just to anchor it for a solid attachment a 1/2" x 4" with a larger washer will work. from there you can 5/8" and 3/4" if need be but if you did you'd probably be using a heavier bracket

Yes. The special "L" shaped ones are usually recommended. Home depot has them in 50-pavks, I'm not sure about smaller or singles. You might call your local store to find out.

I used them for patio posts. Where the load comes from above. Having used a number of them. I do not believe they will provide the lateral stability need for a fence that will see wind and other lateral forces such as kids, dogs etc..... Hope this helps.

this product was used for a new pergola addition that is attached to the house. it served our purposes great, the only downside was the pilot holes had to be redrilled in order to get the tapcon screws to go in all the way. There isn't enough clearance for the head of the drill if you use the holed provided. Once installed they were super solid and worked perfectly!

I used two of these to anchor the stair rail posts at the base of stairs to a new deck I built. I also have angle ties anchoring the stair stringers to the concrete pad on the other side. By tying the posts to the post base and the stringers it made everything very sturdy.

When I build or repair something the first thing that I require is functionally sound and aesthetically pleasing solutions. This particular bracket has both of these qualities and therefore passed the quality control test. Combined with the pressure treated lumber and deck screws this project is aesthetically pleasing and functionally sound. Our soon to be 15y old dog "Sandy" appreciates this ramp everyday.
