Introduction
Your new nose and door puller kit contains all the essential
components normally used to effectively open most safe
deposit locks. Each component is designed to perform a specific function. When used correctly,
these tools will last a lifetime with a minimum of care or
service.
PNP-1000 Nose Puller
The PNP-1000 Nose Puller is designed to be an all
in one type puller.
Additional tools or accessories are not required to
effectively extract most key plugs from industry standard
safe deposit locks.
The primary components are listed on the following
page.
Each component has a specific purpose.
The handle assembly is made from 33% glass reinforced
nylon and contains a brass, threaded nut.
The puller shaft is made from alloy steel that is
heat treated to RC38-42. The distal portion is custom
machined to accommodate standard 1/4" insert bits.
A #2 Phillips bit is provided with each kit.
The knurled nut is alloy steel that is nickel plated.
The puller cup is made from 33% glass reinforced
nylon and contains a witness slot for viewing progress made
during the extraction process.
The thrust bearing assembly is constrained by an
acetal resin cage, assuring correct alignment of the thrust
bearing components during use.
Using the PNP-1000 Nose Puller
-
Install the # 2 insert bit into the distal
portion of the puller shaft, securing same with the
provided set screw.
Usually, you will have to rotate the handle
assembly to extend the puller shaft and nut beyond the
end of the puller cup to gain adequate access to the set
screw.
-
Position a # 8 or # 10 sheet metal screw on top
of the insert bit.
Guide the knurled nut down and over the screw.
Tighten the knurled nut.
-
Drill a pilot hole into the key plug to be
pulled.
Do not over-drill, limiting the distance to no
more than 3/4".
-
Using
the puller cup as a screwdriver handle, thread the sheet
metal screw into the pre-drilled pilot hole. **Maintain
a perpendicular alignment.**
-
Do not bottom the sheet metal screw against the
key plug.
Hold the puller cup steady and positioned over
the center of the key plug.
Rotate the handle assembly until it is snug
against the puller cup.
Verify perpendicular alignment and clearance
through the witness slot. Re-adjust
the puller cup location by loosening the handle
counterclockwise. Continue
to rotate the handle assembly until the key plug is
extracted.
-
After the key plug is extracted, open the lock
in the manner dictated for the type and brand.

Service Notes
- Best
results are achieved by using a 10X24 Phillips-Head
machine screw.
This requires the additional step of tapping the
pilot hole in key plug.
- Several
safe deposit locks require “weakening” of the horn
prior to extraction of the key plug.
Yale B-201, B-231 and Diebold 175-40 are examples
of locks that require horn weakening.
Weakening is accomplished in several ways.
One method is to utilize a plug-cutting hole saw.
By removing most of the horn to a depth of ˝"
the remaining material will not resist the extraction
process.
Another method is to fracture the horn, using a
block of wood and a stout hammer.
Place the block of wood in contact with the horn.
Apply several short, fast blows with the hammer
to the block of wood.
Once the nose is fractured or weakened, normal
extraction can proceed.
- Use a new screw for each extraction.
- Use only stainless steel screws.
- To prevent screw breakage, do not tighten the
screw to the point where it is tight against the key
plug.
Our experience dictates that leaving the screw
loose on the puller shaft allows the screw to seek its
own level, compensating for misalignment and or lack of
true, perpendicularity.
This is accomplished by adjusting the insert bit
depth within the distal portion of the puller shaft.
Slightly loosening the knurled nut is another
option.
- Stubborn key plugs may require the use of an
adjustable wrench applied to the integral hex nut of the
handle assembly.
- Use GT-85 lubricant or its equivalent to
lubricate the thrust bearing assembly.
Wipe down the entire tool after each use and
store it in the provided case.
