How secure is your camper, trailer, tools, and toys?

Whatever needs to be hauled by a trailer is vulnerable to attack by power tools. Thieves use power tools! Portable angle grinders and power tools are the new norm in trailer theft. The ONLY trailer lock to stand up under a power tool attack, is the SAF Trailer Lock.

Altor decided to tackle and solve this new industry security threat, and made the most secure trailer coupler lock with our patent pending SAF Tech design. The SAF Tech unique geometry of the radial cast steel fin design, destroys the cutting edge on angle grinders up to 5” blades, reciprocating saws, drill bit attacks, as well as defeating traditional tools that attack using brute force like a sledge hammer.

Every other lock can be cut within a matter of seconds.

At ALTOR headquarters, we tested the most popular locks and none stood up longer than 120 seconds against an angle grinder attack. The SAF Trailer Lock, survived a concentrated attack by angle grinder, lasting over an hour and thirty-two minutes of continuous power and brute force tool attack.
