PACLOCK’s patented “9-Series” conical shape greatly reduces frontal drilling attacks. Offers unparalleled security for hasps, vans, trailer couplers, and applications compatible w/ a flat-back puck. The “9-Series” cone puck is made from 304 stainless, which is very difficult to machine and is not susceptible to rusting like 302 or 303. Every Lock, One Key: Use one key for all your security solutions – trailer doors, hitch pins, Pelican cases, or cam locks! The pick/bump resistant 6-pin UCS cylinder allows for 20,000+ key codes. American Manufacturer: Made in USA with global components by a family manufacturer hiring veterans and people with disabilities. Our product line is growing, so if you don’t see your lock, call us! PACLOCK's UCS-9S is machined from 304 stainless steel, making the UCS-9S a killer padlock with superior weatherability and strength! All the benefits of a traditional, hardened steel PACLOCK hockey-puck, but with one amazing feature ~ a cone shaped front! Every other hockey-puck on the planet is flat on the front. The “Cone puck” was conceived and engineered specifically to thwart any type of frontal drilling attack. The cone is especially effective when the puck is situated in a recessed housing that forces the attacker to use longer length drill bits. The UCS-9S has special tapped holes on the back allowing the user to affix this padlock directly to a gate, a door, or anything that swings open. Mounting this padlock to the hasp means no more lost padlocks because the operator forgot about it! It’s flat-back design is better suited for any “shrouded” hasps that typically stepped-back padlocks are used.
