It wouldn't be too difficult if you had a Dremel with the right attachment. But, there are quite a few other products in this same line, and if I am envisioning it correctly what you are trying to.do....there are probably better items with no modification needed. When we used ours, we found the ozco building products website to have better information to help us decide which pieces we exactly needed.
You could try bending the lower bracket flap down to 45 degrees. Then cut your 2x4 at 45 degrees to match. Might work. Just don't over work the bending of the metal as it could stress and break. Good luck.
No, these are not galvanized. But they are powder coated - which, it is my understanding will hold up just fine in exposed weather as long as the powder coating is not damaged. If the metal underneath the powder coating is exposed, it will rust.
The powder coating will not be affected by pressure treated lumber.
No, does not fit actual 2x4 rough dawn lumber...learned the hard way
Hi Liz. Load testing data is not currently available for this item.
Yes, should be fine.
We used on pressure treated 2x4 (1 1/2 x 3 1/2) they were very snug on a couple, but fit without any alteration. The rest fit exactly and securely.
I asked the original question. I believe I had to bend the bottom piece to match the angle of the stair railing at the top of the railing. Overall I'd say it worked pretty well, though it isn't specifically designed for stairs.
