5-Pin REKEYABLE cylinder is standard. Can also be configured to use the same key as all 4-pin padlocks (#1, #3, #5, etc) for NO ADDITIONAL CHARGE

Why brass and stainess steel? Both materials are rust and corrosion proof. Many outdoor-use padlocks are available with brass shackles as an option. For some applications however, a brass shackle may not offer the stregnth and cut resistance that the customer needs.

This is why we developed our own stainess steel shackle to work with Master Lock's #6840 solid brass padlock. You get the rust and corrosion resistance of brass PLUS the stregnth of stainless steel where it's needed the most. As far as we know, no other Master Lock distributor offers this combination.

We can build these Pro Series padlocks to order here to get them to you quickly. Orders of 24 or less will ship the same day you order or the next business day. If you need more than that in a hurry, call us at 1-800-461-0620, we can usually accomodate all requests.
