If you are using the 4 in width of the post to the 4" width of the 2 x4 like a butt joint it will work just fine. you can
I use then for narrow shelves in the back of my cupboards for a single row of cans or spices without a problem.
Sorry, it is not intended for woold shelves it too short.
There is no difference in application or function, other than fasteners and allowable loads are a little different. The A34 is 1 716” x 1 7/16” x 2½” long and is cookie-cut to save material, whereas the A23 is 2” x 1½” x 2¾” and not cookie cut. So the A34 would be more economical since it has less steel. For applications where the connector will be visible, people tend to go towards the A23 for the cleaner look with the square edges. Thank you!
When attached to Douglas Fir or Southern Pine, the A23 has an allowable load of 680 lbs. in the F1 direction and 535 lbs. in the F2 direction (use 0.86 x DF/SP allowable loads for Spruce-Pine-Fir or Hem Fir); please see our website or current Wood Construction Connectors catalog for complete information. Thank you!
It's not hurricane grade. As for the open car port. It being open make it easier for it to be destroyed/swept away by the force.
