Master Lock 8413 Adjustable Locking Cable, 6 Foot (3.7m) Long x 3/8" (10mm) Diameter

The 8413 is a 6 foot braided steel cable at 3/8 inch (10mm) diameter. That length wraps a job box lid and a frame member, or loops several tools together, and the 3/8 inch braid stays flexible enough to thread through tight guards and trigger openings where a stiffer cable will not pass. A strap is built in to gather the slack so the excess does not hang loose.

You can lock it anywhere along its length. The 8413 uses a patented adjustable locking mechanism that clamps the cable tight at any position, so you cinch it down to whatever loop the item needs instead of leaving a long slack loop that can be levered or slipped off. That is the main practical difference between this and a fixed-loop cable lock.

Yes. The 8413 is offered keyed alike (KA) so one key runs every cable, or keyed different (KD) so each has its own key. Keyed alike is what you want when one person is securing multiple job boxes or several gun cases and does not want a ring of keys. Keyed different suits handing individual cables out to different people. Key codes 3210 and 2129 can be requested on a keyed alike order, and you can note whether a substitute keyed alike number is acceptable.

Keyed, using a wafer cylinder. There is no dial or combination on the 8413, so access is controlled by who holds the key rather than who knows a number, which is usually what you want when a cable is shared across a crew and you cannot easily re-set a combination after someone leaves.

It is built for outdoor exposure: rust resistant lock body and a vinyl coated cable. The vinyl also keeps the braid from scratching painted box lids, tool housings, or a gun stock it is wrapped around. Note that Master Lock classes the 8413 as a residential grade product, so for a high-exposure commercial site treat it as a deterrent and securing cable rather than heavy commercial-grade security hardware.

Two application groups: guns and hunting gear, and tools with job boxes and gang boxes. In practice that means running the cable through a receiver or trigger guard and around a fixed point, or threading a gang box lid to the box frame or a rack. It is an auxiliary lock, meaning it adds security to something that already has its own closure, not a replacement for a door lock or a box hasp.

Pick by shape, not by strength alone. A padlock and chain needs a hasp or two fixed rings sized to the shackle, and the chain has to reach. The 8413 threads its cable end through openings a shackle or a chain link will not enter, then cinches to any length, so it works on odd geometry: a lid with no hasp, a group of tools with different profiles, a rack rail. Where you do have a proper hasp and want a hardened shackle, a padlock is the stronger choice. Many crews carry both.

The 8413 uses a wafer cylinder, which Master Lock specifies for pick resistance on this cable. A wafer cylinder is a lower-cost design than a pin tumbler and is common on portable and auxiliary locks rather than on door cylinders, so judge it against other cable locks rather than against a commercial door lock cylinder.
