This bi-fold door glides on a precision chromium beam (Thompson Linear Bearing) and pivots on ball bearings for one-touch, effortless action. Designed by Haik.

Very cool. Can you show us a picture of the hardware?

Hi, I would have love to see a video of the door being machined.

Very nice work indeed.

Here's a detail picture of the hardware... this is the "live" or moving end of the bi-fold door.  The stationary end has the same design just without the linear bearing, you can see that and the gimmick at work in the video I've linked here...

Unfortunately, I did not video the machining of the door... but I did snap a pic at the end.  Also, I've included 2 screenshots from when I was doing the design.  Fun stuff that I will be doing more of for sure!!

Thanks for the video. I never would have figured it out from the pic.
