I dono what to call it so been calling this the "You Tension" Because it looks like a U shape

Check it out i put a video of how it functions at the bottom i made also.
"You Tension Original Horizontal"

"You Tension Vertical Version"
(Didn't have time to shave the top post so in finalized one would take up less space by pins)

The Mini vertical Concept

The larger version of "You Tension" (I feel like its trying to tell me something?)

Even larger version leaves room in small keyways

How i have been doing my top of keyways mostly.

Horizontal Option

Upside Down Option to still have top of keyway

My response to not having Falle Tensioners
