Product Description

Master Lock 50mm Combination Padlock (Solid Brass) – Keyless Combination Lock

Instantly establish heavy-duty, keyless access control on critical commercial and residential perimeters with the formidable, highly durable Master Lock 50mm Combination Padlock (651DAU). In demanding environments like shared storage units, commercial toolboxes, and active construction gates, managing and distributing physical keys to multiple staff members is a massive logistical nightmare. This elite, heavy-duty keyless combination lock acts as the ultimate access management solution. It operates entirely via a highly secure, 4-digit set-your-own numeric dial system, providing 10,000 unique possible code variations. This allows facility managers to grant instant access to authorized personnel without ever cutting a single key.

Engineered for unwavering commercial durability and absolute worksite convenience, the 651DAU features a massive 50mm wide solid brass body. This heavy-duty footprint provides terrifying physical strength against brute-force hammer strikes while being completely immune to rust, making it exceptionally reliable in brutal outdoor weather. Fortified with a highly cut-resistant 9mm hardened steel shackle, it aggressively destroys the blades of opportunistic bolt cutters. The highly ergonomic dual-sided dials and rapid push-button opening mechanism allow for instant, one-handed operation even in dark, confined spaces. Supplied as a highly economical boxed set of 4 padlocks, this rugged brass padlock is the definitive, hassle-free security upgrade for modern, high-traffic facilities.

Who Is The Master Lock 50mm Combination Padlock Ideal For?

This massive 50mm padlock delivers heavy-duty keyless access, solid brass construction, and a 9mm steel shackle. It is highly recommended for:

Commercial Storage Facilities: Utilizing a highly reliable keyless combination lock to perfectly secure massive roller doors on storage units, allowing owners to securely grant access to removalists without mailing them a physical key.
Construction & Tradespeople: Relying on the incredibly tough 9mm hardened steel shackle to safely lock up heavy-duty jobsite toolboxes and generators, protecting expensive tools from aggressive bolt-cutter theft.
Shared Residential Gates: Providing a secure, keyless entry point for heavy perimeter side gates, allowing multiple family members, gardeners, or pool cleaners to access the property simply by knowing the 4-digit code.
Facility Managers: Slashing administrative costs by deploying a massive Box of 4 brass padlocks. The resettable combinations allow them to instantly change the access code when a contractor finishes a job, maintaining absolute security.

Key Features and Performance Benefits:

4-Digit Resettable Combination: The ultimate keyless convenience. The lock features 4 numbered dials, giving you exactly 10,000 possible code combinations. You can easily reset the code at any time to a number you will remember, entirely eliminating the need for keys.
Massive 50mm Solid Brass Body: Forged for extreme survival. The heavy-duty 50mm body is cast from solid brass. This provides massive physical strength to survive violent hammer strikes, while being completely and totally immune to rust and weather corrosion.
9mm Hardened Steel Shackle: The absolute deterrent against cutting tools. The thick 9mm shackle is forged from heavy hardened steel, making it incredibly difficult for opportunistic thieves to cut with standard saws or medium bolt cutters.
Rapid Push-Button Access: Extremely ergonomic design. Once you spin the dials to the correct code, you simply press the button on the bottom of the lock, and the shackle springs open instantly, allowing for rapid, one-handed access.
Double Deadbolt Locking Mechanism: Absolute brute-force resistance. This advanced internal mechanism locks BOTH sides of the heavy steel shackle tightly, violently resisting aggressive prying and extreme pulling force.

Frequently Asked Questions

What makes a 50mm padlock better than a 40mm padlock?

A 50mm body width provides a much heavier, more massive physical presence. It is considered a heavy-duty commercial footprint, offering vastly superior resistance against hammer blows and acting as a much stronger visual deterrent than a smaller 40mm lock.

Can I change the combination to a number I want?

YES! The combination is fully 'Resettable'. When the lock is open, you follow the simple instructions included in the packaging to program your own unique, memorable 4-digit code (like a birth year or pin number). You can change it as many times as you like.

What happens if I forget my code?

If you forget your custom code and the lock is closed, there is absolutely no override key or 'master reset' button. For security reasons, you will be permanently locked out and will have to physically cut the massive 9mm shackle off to open it. Always write your code down!

Is the Solid Brass body good for outdoor use?

Yes, absolutely. Solid brass is naturally 100% immune to rust and corrosion. Unlike cheap steel locks that seize up in the rain, this solid brass body will survive brutal outdoor weather, making it excellent for heavy garden gates and tool sheds.

How does the 'Push-Button' mechanism work?

Unlike traditional combination locks where you have to physically pull the heavy shackle up to open it, this model is spring-loaded. Once you dial the correct code, you press the button on the bottom of the lock, and the shackle pops open automatically.

What does 'Double Deadbolt Locking' mean?

Cheap padlocks use a single, spring-loaded latch to hold the shackle down. A double deadbolt physically locks into deep notches on BOTH sides of the steel shackle, making the lock completely immune to being violently pried or hammered open.

Why are the dials on the side instead of the bottom?

Side-mounted dials are vastly more ergonomic. When the heavy 50mm lock is hanging from a gate, you can look straight at the side and spin the numbers easily. Bottom dials force you to awkwardly twist the lock upside down to read the numbers.

Will the 9mm shackle fit my gym locker?

Likely NO. A 9mm thick shackle is designed for heavy-duty commercial hasps, thick security chains, and large gate latches. It is generally too thick to fit through the tiny holes on standard personal gym lockers or luggage zippers.

How many locks are in this package?

This specific listing is for a highly economical bulk carton containing exactly four (4) individual Master Lock 651DAU padlocks, making it perfect for outfitting multiple gates or a fleet of worksite toolboxes.

Can I set all 4 locks to have the exact same code?

Yes, absolutely! Because they are all 'Set-Your-Own' combination locks, you can easily program all four locks to open using the exact same 4-digit code, providing incredible convenience for you and your staff.

Is it difficult to pick the combination?

Because the lock features 4 separate numbered dials, there are exactly 10,000 unique possible code combinations. This makes it mathematically incredibly difficult and time-consuming for a thief to 'guess' your code.

Do you offer trade pricing for commercial facilities?

Yes, Freshway Supplies provides highly competitive volume pricing and trade accounts for construction firms, self-storage facilities, and facility managers ordering bulk cartons of combination locks. Contact us to establish your account.
