Measure Twice Cut Thrice

I have baby gates across the bedroom door to keep Shadow separated from Beeper.

The bottom two gates are swing-out style and have two lugs on the door-frame that accept pins on the door.

The top gate has always been difficult to get closed, but the bottom one has always been fine.

I used the provided template to place the lugs, so I assumed it was some kind of tolerance stack-up problem with the gates themselves.

Swapping them top to bottom helped a lot.  The bottom one was noticeably tighter, but still worked correctly.  The top one got looser, but still bound up on the top lug.

So I measured the fit between the lugs and pins on the bottom gate and replicated that on the top.

It amounted to lowering the top lug about 1/8".

Then I measured between the lugs and they now match!

Somehow I got the top lug 1/8" too high when I mounted them initially.

Worse, I replicated this mistake when I lowered the top gate to narrow the gap to allow it to become the middle gate.
