Innorel P254c Spreading Disk

Innorel P254c Spreading Disk for the tripod legs to fix them in the open condition, preventing accidental close and tripod flip with all the equipment mounted over it (telescope mount and the telescope itself, in my case). I decided to make the disk easy for quick install even on darkness while stargazing or astrophotography. Therefore the disk is round' and is locked by the tripod small centre column locking ball; it snaps over it easily', but releasing needs a tight force on the ball. The design contains also two small holes for attaching to the tripod column.
