The shackle is the part that gets cut, so it is the part to read · review
The only lock here that puts a number on its shackle — four thousand pounds — and one of three that shields it.
The conclusion Twelve dollars sixty for the only lock on this shelf that puts a figure on its shackle — up to 4000 lb of cut strength — inside a round shielded body that denies a bolt cutter its purchase, with no key to lose and a code you can reset. For a locker, a bike or a container that is the right combination of facts. The figure has no standard behind it, the diameter is unpublished, and the plated shackle and die-cast body belong indoors rather than on a weather-facing gate.
No shackle diameter. No test standard. No weather statement.
Four thousand pounds.
It is the only cut strength figure on the whole shelf, and the only measure that speaks directly to this shelf’s introduction: every padlock is attacked at the shackle.
Four thousand pounds is beyond hand pressure on a mid-sized bolt cutter, and within reach of a large one with long handles.
No test method, no laboratory, no standard. Treat it as the maker’s own measurement.
At least six of the fourteen locks here offer only an adjective.
Rather than resisting it.
A bolt cutter has to get its jaws around the shackle. A shield denies it the purchase.
A thicker exposed shackle resists force. A shielded one declines to offer a target.
This shelf’s introduction calls a closed shackle the single biggest step up available in this family. Three locks on this shelf shield; the only published shackle diameter among the American listings here belongs to a lock that advertises being extended.
For a locker.
A four-dial resettable combination means nothing to lose, nothing to copy and nothing to cut a spare of.
It also means a forgotten code is a cut-off lock, and no proof of ownership.
Which Brinks does not claim.
The stated uses are lockers, bikes and storage containers.
A zinc-plated steel shackle facing rain is what this shelf’s introduction calls the plated component that will seize by spring.
The brass lock on this shelf is the one built for a gate.
On sale at around $13 on the American Amazon store at the time of checking.

| Cut strength | Up to 4000 lb, stated for the steel shackle. It is the ONLY cut strength figure published on this shelf, and it is the one measure that speaks directly to this shelf's introduction — which says every padlock is attacked at the shackle. No test standard or method is named with it |
|---|---|
| Shrouding | A round shielded design stated to minimize shackle exposure and protect against cutting. It is one of three locks on this shelf that shield the shackle, and this shelf's introduction calls a closed-shackle design the single biggest step up available in this family |
| Shackle | Zinc-plated hardened steel, stated for cut resistance. No diameter is published, as on at least six of the fourteen padlocks here |
| Body | 40 mm (1.57 in) zinc die-cast. Die-cast zinc is the weaker of the two body constructions on this shelf — laminated steel resists a hammer better — and it is lighter and does not rust |
| Cylinder | None: a 4-dial combination, stated easy to set, use and reset. No key exists, which is the point for a locker |
| Weather | Not stated. The body is zinc die-cast and the shackle zinc-plated steel, and this shelf's introduction warns that a plated steel component on a weather-facing gate will seize by spring. Brinks names lockers, bikes and storage containers rather than gates |
| Keys | Not applicable. A resettable combination means nothing to lose and nothing to copy, and also nothing to prove you own the lock if you forget the code |
| Supplied | One padlock. Price per lock is twelve dollars fifty-nine, mid-range for this shelf |
| Stated for | School and gym lockers, bikes and storage containers — stated, and notably not gates or outdoor hasps |

That Brinks is prepared to put a number on the shackle, which nobody else on this shelf does — and that the number has no standard behind it. Four thousand pounds of force is substantial, well beyond hand pressure on a mid-sized bolt cutter and within reach of a large one with long handles or a hydraulic cutter. No test method, no laboratory and no standard is named, so treat it as the maker's own measurement rather than a certified grade. It is still more than an adjective, and at least six of the fourteen locks here offer only adjectives.
Usually, and this shelf's introduction says so plainly: a closed-shackle design leaves only a few millimeters visible and is the single biggest step up available in this family. The reason is mechanical — a bolt cutter needs to get its jaws around the shackle, and a shield denies it the purchase rather than resisting the force. A thicker exposed shackle resists; a shielded one refuses the attack. Three locks on this shelf shield, including this one and the D-profile lock here, and the only shackle diameter published among the American listings here belongs to a lock that advertises being extended.
Brinks does not suggest it, and the specification agrees. The stated uses are school and gym lockers, bikes and storage containers — indoor or sheltered places where a combination is the convenience and weather is not the problem. A zinc-plated steel shackle on a gate that faces rain is what this shelf's introduction describes as the plated steel component that will seize by spring. For an outdoor gate the brass lock on this shelf is the one built for it, and the chrome-over-steel lock with brass and stainless internals is the one built to survive salt.

| Model | Price | Shackle | Body |
|---|---|---|---|
| BRINKS 175-50054 4-dial resettable sports padlock, 40 mm | $13 | Zinc-plated hardened steel, stated for cut resistance. No diameter is published, as on at least six of the fourteen padlocks here | 40 mm (1.57 in) zinc die-cast. Die-cast zinc is the weaker of the two body constructions on this shelf — laminated steel resists a hammer better — and it is lighter and does not rust |
| Mindy 40 mm shrouded hardened keyed padlock, 3 keys | $14 | Hardened, stated. No diameter, no alloy and no length appears. Mindy describes the lock as professional grade hardened BASE METAL, which is not a material: base metal means any non-precious metal | 40 mm (1.57 in), stated in the title. No material and no construction — not laminated, not die-cast, not brass |
| SEPOX 40 mm all-weather solid brass padlock, keyed alike, 2-pack | $14 | Brass, stated: a durable brass body AND shackle resisting corrosion. That is the unusual half — most weatherproof padlocks pair a brass body with a steel shackle. Brass is softer than hardened steel, so this trades cut resistance for a lock that will still turn after a winter | Solid brass, 40 mm (1.57 in), with a chamfered edge — stated. This shelf's introduction asks for a brass or stainless body on a gate that faces weather rather than a plated steel one that will seize by spring, and this is the only solid brass body on this shelf |
| NovLock NLCL004 | $10 | 7 mm (0.28 in) hardened steel | Solid zinc die-cast |
