Stainless Steel (IN STOCK - READY TO SHIP) 

Model 400-SS puck padlock with hidden shackle  (2 Medeco M3 keys included) 

Machined from a solid bar of 303 Stainless Steel and fitted with a 6 pin pick resistant cylinder. 

Medeco M3 High Security Cylinders feature UL437 Listed physical strength components like the triple locking technology for ultimate pick resistance and solid brass construction with strategically placed hardened inserts to thwart drilling attacks. 

This model is a great upgrade for our coupler lock system. 400-SS version puck lock has no step-back. This product is not meant to be used with rear or side door HASP of trailers due to the inconsistent gap that the trailer manufacturers hold. Model 400-SS puck lock is precision and works as an upgrade for our coupler lock system. If you purchase this model for trailer doors it will be at your own risk and you most likely have to correct the gap on your trailer doors. **Please see our 400XL Model for rear and side doors**
