The “O” tool is a light forcible
entry tool designed for through-the-lock forcible entry. The tool has 3 pieces that make up the tool
set.
The first part of the O tool set
is the bar itself. The bar is 17” long and weighs 2 ˝ pounds. It is made of 4130 aircraft steel heat
treated to Rockwell #42 specifications.
The steel shaft of the tool is dropped forged and recessed into the tool
head and then heat pressed.
The head of the tool has a flat
striking surface with an “A” tool machined into the adz. The “A” tool will remove the lock cylinders
from both mortise and rim locks and will also remove the doorknobs from
key-in-the-knob locks and tubular locks.
The second part of the set is the
“key tool”. The key tool is carried in a small pocket underneath the celetex
grip on the tool. Without this key, you
cannot accomplish through-the-lock entry.
Make sure that the key tool is there at the start of every tour and
after each time the tool is used.

Attached to the “O” tool is a
shove knife. The shove knife is used to
slip the spring on latch locks.
TOOL USE:
·
To pull a lock cylinder
o
Tap the “A” tool down over the top of the lock
cylinder. Drive the tool down
sufficiently enough the blades of the tool bite into the soft brass lock body.
o
When you are satisfied you have a good purchase,
pry UP on the end of the tool and remove the lock cylinder.
o
Look at the back of the lock. If there is a “tail”, you will need to use
the screwdriver end of the key tool. If
there is a cam, you will need to use the “cam” end or angled end of the key
tool.
o
Insert the correct end of the key tool and open
the lock.
o
When using the cam end, remember the 5 o’clock 7
o’clock positionings of mast cams. First
look at the 7 o’clock position. If the
cam lever is there, move it to 5 o’clock.
If its at 5 o’clock, move it to 7 o’clock.
TOOL MAINTENANCE:
·
Keep cutting blades of the “A” tool sharp.
·
Keep the striking surfaces free of burred edges.
·
Keep the tool lightly oiled.
