"I wonder what an "anti-climbing" section might look like?"

So far, they are using a 4 to 6 foot flat plate at the top, which affords no handhold. This year's appropriation limits construction to previously used designs. Next year they might start putting the barrel tops on them, which are even harder to climb, and also defeat grappling hooks.

What is going in now are 18 to 30 foot steel bollards, with the flat plate at the top. 18 foot deters all but teams of fit young men, 30 foot deters all but virtual commandos or circus acrobats.

These new bollard barriers are much heavier material - they will persist for decades without maintenance.

Here is a picture of the current 18 foot design:

I liked the design where the top was wider than the wall, and rounded.

Bbbbbut, the media the Democrats say we are not being invaded.

Why aren’t the top sections welded together? That’s reinforcing strength if they get a large enough, heavy enough vehicle to ram it.
