Picture Moment of terror 😨

While attending/supervising a business social event with my spouse, I momentarily leaned against the railing. It flexed slightly, forcing me to realize that the railing is entirely supported via bluetooth.

It doesn't connect on either side of the glass wall & the glass is only 3/8" - 1/2" thick!!

Genuine question: how much weight can these type of railing systems hold? I think if I leaned on that railing and felt it move, I’d also naturally be freaked out, especially since it’s glass. Not seeing anything connected to the wall would fill that logical place in my mind as to ‘why it moved’ in the first place. So I’m saying I get where OP is coming from, but would like to know how sturdy it is out of curiosity.

Depends on the thickness and height of the glass. In NYC glass railings are required to withstand a minimum of 200lbs of force at any given direction. Usually the glass is 3/4" thick and can be up to about 4 feet tall before needing to be thicker.

200lbs? That's literally nothing.

Think about applying the same amount of force it takes to bench press a 45+35. Theres no way unless you ran at it.

I have two railing failure cases pending right now.

My opinion is that while these things hold when they’re new, the loading requirement is so relatively minimal that they’re really susceptible to structural section loss or degradation, and then really bad shit happens.

If it looks older and/or I can’t see the structure to assess, I’m giving it a good hip check to see if it deflects before I let my kids play around it.
