Built for the Hallway Where Thieves Shop

Storage break-ins happen fast and with bolt cutters. Every part of the VaultDisc 70 is designed to make your door the one they walk past.

Recessed Shroud

Once it's locked on the latch, less than 4mm of the 9.5mm shackle shows. 36-inch cutter jaws slide off the curved steel shoulders.

304 Marine Stainless

The 1.8mm shell handles coastal humidity, road salt, and sideways rain without rust stains on your door.

Universal Roll-Up Fit

The 70mm body and 9.5mm shackle thread through standard storage slide latches, trailer cam bars, and shed hasps 10mm or wider.

3 Keys Included

One for your keyring, one for your partner, one for the kitchen drawer. Unrestricted blanks copy at any hardware store.

How the VaultDisc 70 Keeps Your Unit Shut

The shroud hides the shackle

The shroud hides the shackle

The 20 x 12mm throat hugs the latch staple, leaving less than 4mm of shackle exposed. Bolt-cutter jaws hit solid curved steel instead.

A deadbolt, not a spring

A deadbolt, not a spring

The key turns the curved 9.5mm shackle 180 degrees along a precision internal track. It can't be shimmed open like a spring-pop padlock.

Brass core that drains

Brass core that drains

The solid brass 5-pin cylinder won't corrode, and a 3mm weep hole beside it lets water drain out before it can freeze in the pins.

Description

Why a disc lock?: Bolt cutters need a gap to bite into. The round shrouded body covers almost the whole shackle once it's on the latch, which is why most storage facilities require disc locks.

Built for outdoors: The 304 stainless shell, solid brass cylinder, and bottom weep hole handle rain, road salt, and temperatures from -10°F to 115°F without seizing.

Guarantee and warranty: You get 30 days to make sure it fits your latch, plus a 2-year warranty against seizing from rain, sleet, or road salt. If the core or shackle locks up, we send a replacement.

5–7 Day Shipping & 30-Day Returns

Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.

30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.

2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.

Why Choose the Cosari VaultDisc 70?

Cosari VaultDisc 70 Detail

360° Continuous Weld

The shell is welded all the way around instead of folded and crimped, so a screwdriver or pry bar has no seam to start on.

Anti-Seize Brass 5-Pin Core

Solid brass doesn't corrode like zinc, and five pins give pickers more to work through than the 4-pin cores in many big-box locks.

Key-Retaining Deadbolt

The key stays in until the shackle is fully locked. If the key is in your pocket, the door is shut.

Fits our 10x20 Extra Space roll-up latch like it was custom machined

Public Storage and Extra Space wanted $29.99 at the front desk for a super light stamped disc lock with two flimsy keys. Bought this heavy 304 stainless VaultDisc instead—you can literally feel the weight difference in your palm. Once it's clicked onto our 10x20 roll-up slide latch, you can't even slip a pinky nail near the shackle, let alone bolt cutter jaws.

Six months on my enclosed work trailer and zero rust stains

I'm a general contractor with a 7x14 enclosed Wells Cargo trailer parked outdoors year-round. Replaced two rusted-out hardware store locks with these. After six months of rain and road salt there are zero rust stains running down my white trailer doors, and it comes with THREE keys right out of the gate—one on my truck ring, one for my foreman, and one on my garage pegboard.

Thieves walked right past my unit last Tuesday night

Someone hit 6 units at our self-storage facility last Tuesday night—every single unit broken into had a regular U-shackle padlock snipped clean with bolt cutters. They walked right past my VaultDisc 70 without leaving a scratch. Best peace of mind you can buy.

Key-retaining cylinder saves me from my own forgetfulness

Love that the cylinder is key-retaining. You physically cannot pull the key out until the shackle is 100% rotated and deadbolted inside the hasp, which stops my scatterbrained self from thinking I locked the backyard shed when I didn't. Just a clean mechanical click open and click shut.

No crunchy resistance even after freezing rain

My biggest fear wasn't even thieves, it was showing up with movers in January and having a cheap zinc cylinder frozen shut. The key glide on this brass 5-pin cylinder is smooth as butter with zero wiggle, and the tiny weep hole on the bottom keeps water from pooling inside the pins.

Continuous weld around the seam—not a folded lip

Look closely at the continuous weld around the edge compared to cheap folded-lip disc locks sold at the storage counter. You aren't popping this shell open with a screwdriver or pry bar. Dropped my old Chateau lock once on the asphalt driveway and the shell dented enough to jam the bolt forever; this VaultDisc feels like a solid hockey puck of brushed steel.

Dead-on 9.5mm shackle slides right through CubeSmart latches

Measured the shackle with my shop calipers before heading over to CubeSmart: dead-on 9.5mm hardened steel and 20mm opening clearance. Slides right through standard roll-up door latches without hanging up or scraping your knuckles.

Three solid brass keys included instead of two

ABUS wanted $72 at the local locksmith and only gave me two keys. Getting three thick nickel-plated brass keys with a heavy 245g 304 stainless lock at 50% off was a no-brainer for our family storage unit.

Tank of a lock—just check your gate hasp hole first

Put one on our climate-controlled storage unit and bought a second for our backyard cedar gate. The 9.5mm shackle is beefy, so I had to widen the staple on my old wooden gate hardware by about a millimeter, but on the storage roll-up door it dropped right in.

Zero rattle on the back of a utility trailer

Fits snugly over the cam-bar latch on my landscape trailer. Because the shrouded body hugs the hasp so tightly, it doesn't bounce around and chip the paint while driving down the highway.

Frequently Asked Questions

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

Yes. The 70mm body, 9.5mm shackle, and 20 x 12mm shroud throat match the standard roll-up slide latch used at those facilities. It won't replace the recessed round cylinder-hole inserts found at a few newer climate-controlled facilities.

How many keys come in the box, and can I get copies made?

Three nickel-plated brass keys are included. They're cut on an unrestricted brass blank, so any hardware store or locksmith can duplicate them.

Will it rust on an outdoor trailer or boat dock?

The shell is 304 stainless steel and the cylinder is solid brass, so neither rusts. A 3mm weep hole under the keyway lets water drain out instead of sitting in the pins.

Can the key fall out while the lock is open?

No. The key stays in the cylinder until the shackle is fully rotated and deadbolted. If you can pull the key out, the lock is shut.

If I buy more than one, are they keyed alike?

Each pack option on the product page states whether its locks are keyed alike or keyed differently, so you can choose before checkout.

What if it doesn't fit my latch or the core seizes up?

Take it to your unit, trailer, or shed. If it doesn't fit your latch, return it within 30 days for a full refund. If the core or shackle seizes from rain, sleet, or road salt within 2 years, we send you a replacement.
