Shurlok SL-300W – Frequently Asked Questions
1) Does the Shurlok SL-100 lock box use one combination for the shackle and another for the key door?
Yes, and that is the point of the SL-100. One combination releases the shackle so the box can be taken off the door or railing, and a separate combination opens the key compartment. Give a cleaner or a subcontractor only the key compartment code and they can get the keys without ever being able to remove the box.
2) How many keys fit inside a Shurlok SL-100 key lock box?
Up to five keys. The key compartment measures 1-3/8 inches with a 9/16 inch opening, so it takes a handful of standard door keys, not a fob, a card, or a bunch on a large ring. If you are staging keys for a turnover crew, count on five flat keys per box.
3) Will a Shurlok SL-100 shackle fit over a door lever or a gate railing?
The shackle is 7/32 inch thick, 7/16 inch with the protective cover over it, and the overall height with shackle and body is 5-1/2 inches. That clears a standard lever or knob neck and most fence and railing rails. On a fixed post or a rail thicker than the shackle opening allows, mount it instead, mounting hardware is included.
4) How do you change the combination on a Shurlok combination key lock box?
You set your own code on the SL-100 at any time, and recombinating takes seconds. That matters on turnover: reset the key compartment code after a contractor finishes rather than replacing the box. There are 10,000 possible combinations on the dials.
5) Can the Shurlok SL-100 be wall mounted instead of hung on a door?
Yes. Mounting hardware ships with the SL-100, so you can fix it to a wall, a post, or a jamb at a vacation rental or a job trailer rather than hanging it off the lever. Hanging by the shackle is the other option, it is the same box either way.
6) Is a dial-style key box or a push-button one better for a crew working after dark?
Dial style is the one that works in the dark here. The SL-100 uses zero locking: roll the dial up and away from you to zero, then count the numbers up, so a maintenance tech can open it by feel and clicks with no light. It also does not force a start-over, if you fumble one digit you just fix that digit instead of resetting the whole sequence. Push-button boxes generally need you to see the pad.
7) Is the Shurlok SL-100 lock box tough enough for a construction site?
It is built as a commercial box: solid metal body, hardened steel shackle, chrome plated brass dials, and a protective back. Shurlok lists construction sites, vehicles, and boat lockers among its applications. Treat it as a key control device, not a security barrier, its job is keeping keys off a nail in the site trailer.
8) Can a Shurlok SL-100 be used as a regular padlock as well as a key box?
It locks like a padlock, the shackle is released by its own combination, but the body is a key compartment rather than a solid padlock case. Use it to secure a locker, a gate hasp, or a bike where you also want keys stored inside. If you need a lock whose only job is holding a hasp shut under abuse, buy a purpose built padlock instead.
9) What colors does the Shurlok SL-100 come in, and can I color code units across a property?
Three colors: blue, black, and red. On a multi building portfolio that is enough to code by function or building, say red for emergency and mechanical room keys, black for unit turnovers. The box is identical across all three, only the finish changes.
10) How big is the Shurlok SL-100 key box body?
Body width is 2-1/2 inches, with a height of 1-5/8 inches and a width of 1-3/8 inches stated for the box, and 5-1/2 inches overall once the shackle is counted. Useful when you are checking clearance behind a storm door or inside a meter cabinet before you hang a dozen of them.
