Von Morris in either the Buckingham or Earlham trim.
The slide bolts
will be mounted on the inside of the normally closed door, one at the
top and one at the bottom of the lock stile. The top bolt will need to
be longer on very tall doors in order to reach them without the aid of a
stool or ladder. For example, if the highest you can reach is 80
inches and your door is 90 inches tall, you could select an 8-inch bolt
for the bottom, but you would need at least a 12-inch bolt for the top.
