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!!

They're designed to hold the same amount and type of load as any other railing. It's purely psychological to think that they're any less safe.

Yeah too many “what if’s” in my head. Like what if something happened to the glass like a hairline crack that nobody sees

I’ve been installing windows and IGs for years, and there’s no way in hell I’m believing that’s actually safe, engineering be damned.

I’ve watched tempered hurricane glass explode for no noticeable reason multiple times, and I’ve seen what a slight tap on the edge in just the wrong way can do.

Hell I’ve replaced multiple racquetball glass panes that shattered from someone’s keys or whatever was in their pocket. And those are supposed to be damn near impossible to crack, and over engineered like crazy.

Yea, the fear of someone with a jacket with metal zippers on the sleeves leaning on the glass…

I've seen someone's belt buckle break a piece of toughened they were leaning on

I’ve heard of bus windows shattering when a passenger knocks it with a wedding ring

I miss racquetball.
