*"Bump-Proof"
is a term used to refer to locks that have been engineered to resist
"Bumping".
Mul-T-Lock Ltd.
is a worldwide leader in developing, manufacturing and marketing High
Security products for institutional, commercial, industrial and
residential applications.
Mul-T-Lock® high security
cylinders have a unique telescopic pin tumbler mechanism with internal and
external pins. Both the internal and the external shear lines must be
aligned simultaneously in order for the plug to rotate.
The Mul-T-Lock patented plug has
a unique structure.
When the top and bottom pins, plug and body meet, a three-dimensional
shear line is formed to an almost perfectly spherical shape.
Steel inserts ensure anti-drilling resistance.
These features provide an added
security dimension and make the Mul-T-Lock cylinder pick-resistant
and drill-resistant for high security needs.
When Master Keyed, additional side pins or back pins can be incorporated.

VARIABLE
COMBINATION CYLINDER 3 IN 1
This cylinder is built to allow a change of combinations by the
insertion and operation of the next key in a sequence of 3 keys.
Introduction of each new key invalidates the previous key combination.
When all 3 combinations have been used, the cylinder may be reset by a
MUL-T-LOCK authorized locksmith. The product is packaged with the 3 key
types, color-coded and clearly marked in a sequence, to guide the
customer in correct usage. First you use the green set of keys.
Whenever the combination needs to be changed, simply start using the
yellow key (Then the green key will automatically be cancelled). Once
again you may change the combination by applying the same process with
the red key. (the yellow key as well as the green will automatically be
cancelled).
A simple color coded idea

combinations.
