Wilson Locking Systems has has introduced a revolutionary
new locking device for aircraft called "PropLock."
Its compact, lightweight foul-proof design makes it ideal for
private pilots and commercial aircraft operators alike. About the
size of a small clock radio (10" X 5" X 2"), PropLock quickly and
easily affixes to the propeller of nearly all general aviation
aircraft. It clamps onto the propeller base close to the airplane
spinner in five to 10 seconds. Any attempt to crank the motor
throws the propeller out of balance creating severe vibration and
preventing take-off.
PropLock operates on a vice grip action. The Z-shaped device
locks with a single turn. PropLock transforms into an elongated egg
shape as the locking cylinder moves into the upper part of the
locking mechanism where it is protected from being drilled out. The
inner cell of the closed lock is protected by a "live" rubber
lining with a 20 to 30 durometer and is UV resistant. The arms of
PropLock are coated with a polyurethane epoxy to prevent scratches
to the propeller when being affixed.
PropLock is formidable. While the body is made from 6061
aluminum, the latch is made from stainless steel, which is
difficult to cut with a cutting torch or hack saw. Yet it is
attractive, compact and lightweight -- about 3 Ibs -- which makes
it easy for pilots to carry. PropLock is powder coated in the
Wilson Locking's signature bright lime green for maximum
visibility, although custom colors are available.
When applied, PropLock allows pilots the flexibility of moving
the aircraft from one hanger to another for maintenance. For those
states that require two locks, Wilson Locking Systems recommends
PropLock be used with a CuffLock, Wilson's patented wheel
immobilizer. Special orders for all sizes of antique and vintage
aircraft are available.
PropLock is one of four complete locking devices currently
available for the transportation and parking industries from Wilson
Locking Systems.
