Knaack box locks

davidmeiland | Posted in General Discussion on January 20, 2004 05:36am

I want to change the locks on my boxes and switch to either a rotary-numeric-combination type or to a type with a round key. They have the usual Master A1 locks that are easy to drill out, and I have to keep track of 3 different keys. Can anyone tell me about a lock that will fit the Knaack lock recess and that’s nice and secure? I want to order them online somewhere if possible because the store here has jack.

    View Image  The Master "Sesamee" lock is sold a Lowes, Home Depot, Target and Walmart.  LIsts at $20, but usually go for $14.  You can set its combination.

    At Lowes and Home Depot the boxes of locks sometimes are all keyed alike, if you can see the number on the key you can verify that.

    Probably not the most indestructible of locks, I removed one pretty quick with a sharp hacksaw and think a whack or three would get it as well but it will be surrounded in the loving embrace of the Knaack box, but I agree with the other guy. These are good. I have had good luck with these changeable combination locks.

    They are great where crews go from one site to another and back, sometimes alternating with another crew using the same box. Who has the key? Are they there today? Has anyone made a copy to use for a midnight raid?

    The beauty of these is that you don't have to actually get a key, across two counties, to the other crew. You can just tell them the combination on the phone to the foreman. Foreman not there? Tell the next guy and change the combination that evening if your worried. No need to scrap the lock. When someone leaves the company, or at random intervals, you can just reset the combination. No need to worry about getting the key back or if they made a copy.

    These units are also fairly weather resistant. Have had one on a shed and in the rain for years and it had never jammed. About once a year I might give it a little WD-40.
