Japanese Advanex's Instant Lock Improves Installation to Ceilings
Add to my favorite
The Advanex "Instant Lock" is a hardware to prevent nuts from loosening and falling. Mount it from below onto a hanger bolt and it is good to go without the need for maintenance. It can be mounted and dismounted single-handedly and effortlessly. It doesn't require any tools nor torque management. Currently it is used in installation to ceilings but will expand its application to other fields.
