Sesamee Weatherproof Padlock: Since 1926, 80 Years of Reliable Security

The Sesamee Weatherproof Combination Padlocks have provided 80 years of reliable security Originally Patented in 1926, the Sesamee Weatherproof Combination Padlock basic design has remained unchanged over the years. The four wheel design which yields 10,000 possible combination changes, uses a solid brass internal platform which has evolved over the years. Sesamee Weatherproof combination padlock

Originally conceived with a multi-piece frame, the 1980’s saw the platform become a solid brass single piece frame. This change along with spring strength increases, shackle modifications, and wheel alignment improvements, made the Sesamee Padlock virtually impossible to pick open by both vandals and professional thieves alike.

If imitation is truly the sincerest form of flattery, the Sesamee Padlock family of products, must be the most respected family of locks in the world.

The Sesamee Weatherproof Combination Padlock design has been copied repeatedly over the years, but the solid brass Sesamee Weatherproof Combination Padlock is still the first name requested on Federal, State and Local government specification sheets when it comes to reliable out-of-doors, weather resistant, combination locks. All Sesamee Padlocks have a limited 1 year warranty.

    Great heavy-duty lock

    Posted by Bob P on Sep 12th 2018

    I like this lock because it is weatherproof, heavy duty and extra secure with all brass internally. In addition, the hole to re-set the combination cannot be accessed from the outside, like Master Lock's similar looking model. I had a Master Lock, but switched it out once I saw the specs on this Sesamee lock. Solid product and good value.

    Great lock for outdoors

    Simple to set combination of your choice. Convenient since I ordered two and can program both with same code. Purpose is for outdoor shed and to back gate around pool.

    exactly what I was looking for

    Posted by Unknown on Oct 5th 2016

    I was looking for a substantial easy to set easy to unlock outdoor programmable padlock - I was completely frustrated with what I could find locally. I had settled for a Brinks brass 3 digit padlock and had regretted the purchase almost immediately. When I saw this padlock online I thought this sounds perfect - boy was I right ! Maybe a little overkill for my needs security wise (OK all the way around) I thought the lock was pricy but my frustration with my first purchase was reaching the point of pitching it out into the field the next time I got it open after 16 attempts. This lock is solid and impressive long before you take it out of the package. It is heavy but what was the combination itself. The pin key is an ingenious method to set it - absolutely no way to accidentally mess up the combo once it's set. So peace of mind that way. No one can reset it without opening it first then you must have the pin key to change the combo - more peace of mind. But the ultimate feature is the rock solid tumblers - no slop - no play - no guessing at positioning of the code #s. The number you spin to is the number you chose - not 1/100" in either direction and it wont open on any or all of the digits. I just purchased this lock so cannot comment to it's longevity but I can tell you that I am certain that I will be able to open it on the first try EVERY time !!! Over all an impressive piece of equipment - cost is actually cheap compared to the excellent quality.

    Posted by Marvin on Aug 26th 2016

    I use this for my boat. I just had to get new locks after 5 years! That's impressive! These locks are exposed to the elements yet they still work perfect.

    Excellent performance in all weather elements outdoors

    Posted by Bradley Johnson on May 6th 2014

    Our company has been using combination locks for years on the gates to our forest properties and have had bad luck over the past few years with other brands. Earlier this year we found the Sesamee Padlock Keyless Marine locks, ordered some to try and so far has been very satisfied with their performance. They have withstood the weather elements very well and are easily opened by everyone at the gate. I've already recommended them to other companies and friends.
