E-Z Base Black Powder-Coated Post Base for 4x4 Nominal Lumber

An update, the use of a hand belt sander, and about a minute'ish on each side the higth of the E-Z Base, and it only takes about 6 or 8 waks with the sledge hammer and its on tight without your arm getting tired. Just sand it a little more if you dont want to use the hammer at all. Have fun all

Drill your holes and use resin anchors to set threaded rods in them (1/2" stainless steel?). Leave to set (very quick) and then tighten the assembly. There will be no expansion forces to crack the concrete. I used this method some 15 years ago to fasten wall plates to the foundations of my house that I was building and it is still standing.

No just for 4 x 4 posts ,wish they made same design for 6 x 6

NEVER Post bases do not provide adequate resistance to prevent rotation about the base and therefore are not recommended for non-top-supported installations such as fences or unbraced carports Warning: The E-Z Base and E-Z Spike products should not be used for solid fences in excess of 4' in height or that are unprotected from wind forces. These products are not rated for uplift loads, and should not be used with posts for overhead structures or any other structure that requires resistance to wind uplift loads. Notwithstanding the terms of the Limited Warranty, Simpson Strong-Tie does not guarantee, represent or warrant that this product will prevent or reduce damage caused by corrosion, or any seismic, wind, atmospheric, or other load-producing event.

The instructions on the label say to use four 1/2-inch anchors to secured the base to concrete - that means fasteners (screws) of 1/2-inch diameter. There are two types of these fasteners - "expansion bolts" and heavy-duty anchor screws. To attach the wooden post to the base, use eight 1/4" SDS or Lag screws

I would think that would work as long as the gate is normal weight

Half-inch fasteners are what Simpson specifies.

Yes, but tall heights and finding straight 4x4’s would be tough. Not knowing the loads your pavilion project would be subject to, like winds, rooof materials, etc a proper amount of planning would be necessary to make it a safe structure. Additionally, cross bracing would certainly be necessary, I’d look into timber frame suppliers and you might find a better solution for your particular project.

Nothing to grab on asphalt.

Mine have been outside for 1 1/2 yrs, no signs of anything wrong. No fading, rust, nothing like that so far.
