Commercial padlock with long shackle

Master Lock commercial padlock K6000 uses a 4 pin cylinder and a long steel shackle for reach around thick hasps. Body is steel with silver finish and measures 1 5/16 in high by 1 3/4 in wide. Two bumpers add cylinder protection. Keyed different, not rekeyable and no control key registration required.

Suits gates and lockers needing extra shackle

Fits padlock hasps where standard shackles cannot reach. Not for buyers who need weather resistance, interchangeable core, or rekeyable cylinders. Not for buyers who need keyed alike sets or master keyed systems. High security rating covers physical attack resistance only.

4 pin Master K6000 keyway decides compatibility

Cylinder accepts only Master K6000 key blanks. Existing Master K6000 keys will not operate this lock unless cut to match. No other keyway works. Verify keyway before purchase to avoid fitment issues.

Questions about this item

How do I install the Master Lock K6000 padlock on a gate and what step is often missed?

Insert the 5/16 inch shackle through both hasp holes, snap the lock body shut, and turn the key to engage the four-pin cylinder; the step people miss is verifying the shackle clicks fully into both locking notches before turning the key.

What maintenance will the Master Lock K6000 padlock need over time?

Apply a light PTFE lubricant into the keyway and shackle holes every six months to keep the four-pin cylinder and steel shackle moving freely; the solid steel body and non-rekeyable core require no internal servicing.

What is the first limit I will hit if the Master Lock K6000 padlock stays locked outdoors in rain?

The specification states the padlock is not weather resistant, so sustained moisture will cause surface corrosion on the steel body and shackle before any mechanical failure of the four-pin cylinder occurs.
