The all-metal Combi-Bolt features a 3/8″ diameter solid steel bolt that slides into a strike or bolt receiver, leaving little of the shackle exposed. Because the shackle is protected, they claim it’s more secure than hasp and padlock designs. Plus with four pick-resistant dials, you get 10,000 possible codes — it goes without saying (but I’ll say it anyway) that it would take a long time guess the right code.
Made with chrome-plated brass dials and coated die-cast body, the Combi-Bolt was designed to withstand the elements. You can install the lock with only a drill (with the right sized bit) and screwdriver. Also included are one-way security screws, a bolt receiver to flush mount the Combi-Bolt, and a strike plate if you wish to recess the lock.
To change the combination: Dial the current combination, lift the handle up, and slide it back until the handle drops again. Then, simply dial the new combination, lift the handle up, and slide the bolt forward. A reviewer on Amazon [What’s This?] claims this procedure might be a little too easy, though, since his wife accidentally reset the combination on him.
Despite listed prices of $20 or less, it looks like it’ll take you $30 to get a Combi-Bolt shipped to your door.
