Built for Doors You Walk Away From

Every part of the VaultDisc 70 is chosen for a lock that hangs outside, unattended, for months at a time.

82% Shrouded Shackle

Only a 20mm × 17mm throat is exposed. Bolt-cutter jaws slide off the curved stainless shoulders instead of biting the 9.5mm hardened shackle.

Real 304 Stainless Body

Solid SUS304 stainless, not chrome plating. No rubber ring to hold rain, and a bottom drain port that lets water run out.

5-Pin Solid Brass Core

A tighter 5-pin cylinder that held past our five-minute pick limit, so a thief can't quietly open it and leave no trace.

3 Thick Milled Keys

2.4mm brass keys that don't flex when the lock is cold. Three in the box, on a standard blank any locksmith can copy.

How the VaultDisc 70 Keeps Your Unit Shut

Nothing for Bolt Cutters to Grab

Nothing for Bolt Cutters to Grab

The 70mm body wraps around 82% of the shackle. Cutter jaws hit curved stainless steel and slip off before they can close.

A Key That Drives, Not a Spring That Rusts

A Key That Drives, Not a Spring That Rusts

Turning the thick brass key moves the shackle directly, like a deadbolt. No pop-spring to corrode, and the key stays captured until the lock is shut.

Sealed Against Weather

Sealed Against Weather

A continuous 360° laser weld and bare stainless finish shed rain and slush. The drain port keeps water from sitting around the cylinder.

Fits flush in our Extra Space roll-up latch with zero room for bolt cutters

Do NOT put a standard padlock on a self-storage door—thieves walk down the row with 36-inch bolt cutters in a gym bag and pop exposed shackles in two seconds. The VaultDisc 70 sits completely flush inside our roll-up door slide latch with maybe 2mm of wiggle room. Good luck getting a pry bar or cutter jaw anywhere near that shrouded shackle. Heavy, clean laser weld all the way around.

Survived Michigan road salt on my cargo trailer without seizing

Ran two of these on the rear and side cam-bar latches of my enclosed Wells Cargo landscape trailer through months of slush and highway salt. Put the key in this week and the brass cylinder turned like butter on the first try—zero orange rust streaks. I also love that you can't pull the key out until the shackle is 100% seated, which kept me from leaving the back door half-latched on day one.

Way smoother than the $28 lock I had to pay maintenance to cut off

I originally bought the 'recommended' disc lock at the storage facility front desk for $28. Five months later the key went in, turned halfway, and froze solid—cost me $50 to have maintenance take an angle grinder to my own lock. Ordered the Cosari as a replacement and the difference in the internal track is night and day. Thick milled brass keys that don't twist like aluminum foil when pushing the bolt.

No plastic bumper trapping rainwater against crimped seams

Learned my lesson with those hardware-store disc locks that wrap a black rubber ring around the edge—that bumper holds Pacific Northwest rainwater right against the folded metal seam until the guts rust shut. The VaultDisc 70 is pure brushed 304 stainless with a continuous welded perimeter. Four months on an outdoor drive-up unit in constant rain and it still operates like the day I put it on.

Three heavy keys included instead of the usual stingy two

We're between houses right now with a 10x20 unit packed to the ceiling. Having three thick brass keys included right away meant my wife, my brother-in-law helping with the truck, and my daily keyring were all covered without hunting down a locksmith who stocks disc blanks. At 295 grams it feels like a solid stainless steel hockey puck in your hand.

German-level build quality without paying $55 per lock

I needed four matching disc locks for two commercial storage bays plus my equipment trailer doors. ABUS makes a great Diskus lock, no question, I just couldn't stomach dropping $220+ on four padlocks. Grabbed four VaultDisc 70s during the 50% off promo and checked the seams right away—continuous clean weld, zero folded tabs, heavy brass core. Couldn't ask for better value.

Zero key-binding even in 15-degree morning temps

Because disc locks use the turn of the key itself to slide the curved shackle around the housing, cheap ones grind and bind up until you feel like the key is going to snap off in the cylinder. This one has a remarkably smooth internal cam. Even at 6:30 AM in 15-degree Denver cold, it rotates cleanly with two fingers and pops open without fighting it.

Peace of mind after an insurance nightmare on an old lock

Two years ago someone raked open a cheap 4-pin brass padlock on my buddy's storage unit and relocked it afterward—renters insurance fought the claim because there was 'no visible sign of forced entry.' Switched both of our bays to the VaultDisc 70. Between the recessed multi-pin cylinder and the shrouded 10mm shackle, nobody is quietly picking or snipping their way into this.

Holds up to coastal salt air—just measure small gate hasps first

Put one on my boat storage bay (fits like a glove) and bought a second for a narrow side yard fence gate. Measure your gate staple first because a true 70mm body with a 10mm shackle is beefy—had to swap my thin $4 fence latch for a heavy-duty hasp so the shackle cleared cleanly. Once mounted, the salty coastal humidity hasn't fazed the 304 stainless one bit.

Continuous perimeter weld passes the hammer check

First thing you should check on any round discus lock is the outer rim. Cheap two-pack locks crimp the front and back plates together with little folded tabs that split like a clam after two hits with a framing hammer. The Cosari shell is continuously welded around the full circumference and ground smooth. Dust and desert grit blow right at my gate all week and a quick turn still opens it effortlessly.

Frequently Asked Questions

Will the VaultDisc 70 fit my Public Storage, Extra Space, CubeSmart or U-Haul unit?

It fits standard roll-up door slide latches and most trailer hasps. The 9.5mm shackle passes through a typical 7/16-inch latch hole. It is not designed for recessed round cylinder inserts found at some newer indoor facilities, so check your door first. If it doesn't fit, return it within 30 days for a full refund.

Will it rust if my unit is outdoors or near the coast?

The body and shackle are 304 stainless steel and the cylinder is solid brass. There's no rubber bumper to trap water, and a drain port at the bottom lets moisture escape. It opened on the first turn after our 14-day salt-spray and freeze test, and it's covered by a 2-year zero-seize replacement promise.

How many keys come with it, and can I get copies made?

Each lock comes with three heavy-gauge 2.4mm milled brass keys. They use a standard blank profile, so most locksmiths can cut copies.

Why won't the key come out when the lock is open?

That's intentional. The lock is key-retaining, so the key stays in until the shackle is fully locked. It means you can never accidentally close the lock with your keys inside the unit or trailer.

Why does it take a full half-turn to open and close?

The VaultDisc 70 uses a positive-drive mechanism. The key moves the shackle directly, like a deadbolt, rather than relying on a spring that can rust or weaken. A 180° turn opens it and another 180° locks it.

Are multi-packs keyed alike?

Check the keying option shown at checkout before you order. Keyed-alike sets let one key open every lock, which is handy for two units or a trailer with side and rear doors.
