ISEO Mortise Lockset

A handy person from Elk Grove Village, IL says:
I need to replace a broken lockset. It looks like your 82-400 might fit.

What is the oc spacing between the handle & key channel in the lock cylinder?

Also if I should ever need a new cylinder what would I need to know (name/type), dimensions, etc) to get one that will fit and do you sell the cylinders?

The measurement between the key hole and lever handle hole is 3" on the 82-400. The width and height of the lock box is 2-1/4" by 7". The back set from the edge of the lock to the lever hole is 1-3/4". Hopefully these measurements help. Check to see if your lock matches up. Also, if you need to just replace the key cylinder, our 40-089 could work as a replacement. Note that the 82-400 takes a Schlage key way, whereas the 40-089 take a Kwik Set key way.
