Cilindro de embutir con pomo giratorio de 1 "

Not sure the correct name of the piece on the cylinder that engages with the lock bolt but it was way smaller than the one on the keyed cylinder I was replacing. Had to remove the one from the old cylinder and replace it on the new cylinder in order for it to work correctly

Fit perfect , mark on thumb turn needed to let me know when it is engaged some other locks do not have that feature.

Easy to install. Put my lock in compliance with city regulation.

Worked fine afterwards
