Who makes it?

[Yankee Chronicler]

Conventional thumbturns for deadbolts, as found in most aluminum storefront doors, require both pinching and twisting of the wrist to operate the deadbolt, so they don't comply with the ADA. I know I have seen deadbolts with extended, paddle-like levers that can be operated by swiping with a palm. I can't find them. Does anyone know who makes these things?

The real question is : Is the thumbturn even allowed?

That's not it. That only works with latchbolts, not deadbolts. I'm looking for things like tose in the link Sifu posted.

If it does not require tight grasping, pinching, twisting of the wrist, single hand operation, with less than 5 pounds of force to operate its been ok. The US Access Board say you can use the closed fist test (although not official). If you can operate it with a single hand closed fist that should do it.

This is the performance criteria I fall back on as best I can. Every "accessible" thumb turn I can recall had a longer lever. In the filed I used the closed fist. Often it required adjustment but usually passed the performance criteria once installed correctly. For plan review I can only request the specification but can't test it, that is left up to the inspector.

I have also seen many properly installed standard thumb-turn bolt levers that would pass the closed fist test, though I can't recall anyone proposing them as accessible.

Accessibility is not the only criteria.....You have to look at egress too...
