Larson QuickFit 5 Sided Spindle Mortise Lock Body NO Trim

Went in easy and works great.

The lLarson lock was delivered quickly. Upon receipt i found that the spring which returns the latch bolt outward was stuck between the latch bolt shaft and the guide hole for the latch bolt shaft. This would not allow the latch bolt outward to engage the strike plate. I had to use pliers and a pick to forcefully remove the end of the spring from it's stuck position in the latch bolt shaft guide hole to get the lock to function properly.
