The lock body combines a metal core with a stainless-steel cover, and the hardened steel shackle measures 9/32 in (7mm) diameter with a 3/4 in (19mm) usable length. An anti-shim locking mechanism is built in specifically to resist one of the more common bypass techniques used against basic combination padlocks.

• The preset 3-digit combination comes set from the factory rather than user-programmable.
• Both locks in the 2-pack share the same combination, so a single code covers 2 separate locations.
• Overall lock body width is 1-7/8 in (48mm), sized for standard locker and cabinet hasps.

The hardened shackle and anti-shim design target everyday theft attempts rather than heavy-duty forced entry, positioning this as an indoor security lock rather than an outdoor gate-grade padlock.

With a 13/16 in (21mm) shackle width and 1-7/8 in (48mm) body, this padlock is sized to fit standard gym lockers, school lockers, cabinets and storage hasps rather than oversized gate or trailer hitch applications. Reading the dial is straightforward thanks to a high-contrast finish that stays legible even in dim locker-room lighting.

• The preset combination means there's no initial setup step, both locks work right out of the packaging.
• Measuring the target hasp or door's backset, cross bore and thickness beforehand is recommended to confirm fit.
• Two identical locks with one shared code simplify multi-locker or backup use without juggling separate combinations.

Because the shackle length is fixed and moderate, it suits thin locker doors and hasps better than a thick gate chain or wide loop application.

This padlock suits students, gym-goers and anyone needing a straightforward lock for indoor lockers, cabinets or storage where a shared preset code across 2 locks is more convenient than programming a custom combination. It's built for everyday indoor theft deterrence rather than high-security or outdoor applications.

• Good fit for shared households or gyms where multiple people need the same access code.
• Suits anyone who prefers not programming a combination lock manually before first use.
• Less suited to outdoor gates, sheds or trailers where a heavier-duty shackle diameter is typically expected.

Anyone needing a lock they can reset to a personal combination, rather than use as preset, should look at Master Lock's user-resettable combination models instead.

The lock uses a 4-digit combination offering 10,000 possible codes, ten times more combinations than a standard 3-digit lock, making it harder to guess or cycle through by trial and error. A side-window design shows the current combination setting so it can be changed one-handed.

• Combination should be scrambled after setting a new code, per the manufacturer's instructions
• No physical key or backup override exists, so the set combination must be remembered or written down securely
• The 1/4-inch shackle diameter fits standard hasp and locker holes sized for that shackle width

Because there is no key backup, losing track of a changed combination means the lock body may need to be cut off to regain access.

Constructed from zinc alloy for the lock body and carbon steel for the shackle, the lock is built to resist hammering, sawing and prying attempts better than lightweight plastic-bodied locks. A weatherproof design allows it to stay mounted outdoors without rusting shut over time.

• Overall size measures 3.15 x 1.73 x 0.87 inches, compact enough for lockers and small hasps
• Resistance to rust and corrosion suits year-round outdoor placement on gates, sheds and fences
• Shackle diameter of 1/4 inch fits most standard locker and hasp openings

Very heavy-duty applications, such as securing high-value equipment or exposed chain-link gates in high-theft areas, may call for a thicker shackle than this lock's 1/4-inch diameter offers.

This lock is sized for everyday security tasks including school and gym lockers, sports bags, toolboxes, fences, gates, storage cabinets and hasp-style latches. Its compact 3.15 x 1.73 x 0.87-inch body keeps it lightweight enough to carry between uses.

• Gym and school lockers benefit from the one-handed side-window combination setting
• Sheds, gates and fences benefit from the weatherproof, rust-resistant construction
• Toolboxes and cabinets are secured without needing to track a physical key

For high-security applications like securing high-value outdoor equipment or motorcycles, a heavier-shackle, high-security padlock would be a better fit than this general-purpose 4-digit lock.

The lock uses a 4-digit dial system offering 10,000 unique code combinations, roughly ten times the number available on a 3-digit lock. A hardened steel shackle with a 0.23-inch diameter provides the physical resistance point against cutting or sawing attempts.

• 4-digit dial supports 10,000 possible combinations
• Hardened steel shackle resists cutting and sawing
• Zinc alloy body adds weight and rigidity to the housing around the dial mechanism

Because the combination is fully resettable by the owner, losing track of a chosen code locks the item away with no backup key; writing the code down somewhere separate from the lock itself is worth doing before first use.

The lock body combines a zinc alloy housing with a hardened steel shackle, finished with an anti-rust treatment aimed at outdoor exposure. Total weight comes in at 0.27 lbs, and overall dimensions measure 3.11 x 1.73 x 0.86 inches (L x W x H).

• Zinc alloy body construction with a weatherproof, anti-rust finish
• Overall weight of 0.27 lbs keeps it light for daily carry
• Compact dimensions of 3.11 x 1.73 x 0.86 inches fit small hasps and lockers

The anti-rust treatment is aimed at general outdoor weather exposure rather than submersion, so it is better suited to a gate or shed hasp than prolonged contact with standing water.

The compact 3.11 x 1.73 x 0.86 inch size and 0.23-inch shackle diameter suit gym lockers, school lockers, cabinets, pantries, toolboxes, and gate or fence hasps rather than heavier-duty applications like storage units or trailers. The side window dial design makes the numbers easy to read even in a crowded locker room.

• Sized for lockers, cabinets, toolboxes and gate or fence hasps
• Large-number side window design aids quick reading in low light
• Single Peacock Blue colorway is the only option in this listing

Larger applications like padlocking a storage container or trailer hitch typically call for a thicker shackle diameter than the 0.23 inches offered here, so this lock is better matched to everyday indoor and light outdoor use.
