The shackle is the part that gets cut, so it is the part to read · review
A D-profile heel-and-toe body with brass and stainless internals — the closest thing on this shelf to the closed shackle the hub asks for.
The conclusion The best-built lock on this shelf: a D-profile body that shrouds most of the shackle, heel-and-toe locking so both legs must be cut, a disc cylinder, key retention and — the detail that justifies thirty-seven dollars — all internal mechanics in brass and stainless steel, which is what keeps an outdoor lock turning. No shackle diameter, the order quantity is never stated, and the fourth bullet names a different model entirely.
No shackle diameter. No order quantity.
Which is what heel and toe means.
On an ordinary padlock the bolt holds one leg of the shackle and the other sits in a hole. Cut the held side and the shackle swings free in a single pass.
Heel and toe locks both legs. The attacker cuts twice.
Add the D-shaped body, which leaves only a short span reachable, and this is the strongest shackle arrangement on this shelf.
This shelf’s introduction calls a closed shackle the single biggest step up in this family. This is FJM’s version of it.
Which is the sentence that justifies the price.
Triple chrome over hardened steel resists weather on the outside. A steel mechanism inside rusts anyway, and seizes.
This shelf’s introduction names that as the outdoor failure that matters: a plated steel lock that will seize by spring.
All internal mechanics brass and stainless steel is the answer to it. A chrome-plated lock at twelve dollars does not say that.
Like six of the seven here.
Eighty millimeters is the body width, not the shackle.
This shelf’s introduction calls diameter in millimeters the first specification that matters. One lock on this shelf gives one.
SPSA80 everywhere, and SPSA60 in the fourth bullet.
The title, the reference and the 3 1/8 inch dimension all agree on 80 mm (3.15 in). The SPSA60 sentence is lifted from the smaller model’s page.
Confirm the size on the order page if it has to fit a particular hasp.
On sale at around $37 on the American Amazon store at the time of checking.

| Shackle | A freely rotating hardened steel shackle with heel-and-toe locking, in a D-shaped body stated to grant very little access for bolt cutters or saws. Heel-and-toe means the shackle is secured at both ends, so cutting one side does not open the lock — both legs must be cut. It is the strongest shackle arrangement on this shelf |
|---|---|
| Diameter | Not published. This shelf's introduction calls diameter in millimeters the first specification that matters, and at least six of the fourteen padlocks on this shelf omit it. The 80 mm (3.15 in) figure in the title is the body width |
| Shrouding | The D-profile is the shrouding: the body rises around the shackle so only a short span is reachable. This shelf's introduction calls a closed-shackle design the single biggest step up available in this family, and this is the nearest to it here |
| Weather | Triple chrome plated hardened steel, stated as uniquely suited to outdoor and marine environments, with ALL internal mechanics in brass and stainless steel. The internals matter more than the plating: a chrome shell over a steel mechanism seizes when the mechanism rusts, and brass and stainless do not |
| Cylinder | A disc mechanism requiring the keyway to turn 90 degrees before engaging the discs — stated, with pick resistance claimed. Disc detainer cylinders are the harder common type to pick |
| Keys | KEY RETAINING: the keys can only be removed when the padlock is locked — stated. Four European-style keys, described as hard to duplicate. At least two of the fourteen padlocks here are key retaining |
| Supplied | Keyed alike, so one key set fits all the locks in the order, with a keyed-different option stated as available. The quantity in this listing is not stated |
| Reference | The title and the product reference read SPSA80 and the body is described as 80 mm (3.15 in), while the fourth bullet reads "The SPSA60 FJM Padlocks come with 4 unique European style keys". Two model numbers on one page |
| Orientation | Applicable vertically or horizontally on storage or shipping containers, stated — which on a D-style lock is not automatic and is the detail that decides whether it fits a container lockbox |
| Amazon reference | B00HR01SSY |
| EAN | 0027536970201 |
That both legs of the shackle are locked into the body, so an attacker has to cut twice. On an ordinary padlock only one leg is held by the bolt and the other sits in a hole — cut the held side and the shackle swings free in one pass. Heel-and-toe doubles the work, and combined with the D-shaped body, which leaves only a short span reachable, it is the strongest shackle arrangement on this shelf. This shelf's introduction calls a closed shackle the single biggest step up in this family; this is the version of that idea FJM sells.
More than the plating suggests, because of one sentence in the fourth group of bullets: all internal mechanics are brass and stainless steel. That is the part that decides whether an outdoor lock still turns next spring. Triple chrome over hardened steel resists the weather on the outside; a steel mechanism inside rusts regardless and seizes, which this shelf's introduction describes as the failure that matters outdoors. Brass and stainless internals are why this costs thirty-seven dollars and a chrome-plated lock at twelve does not.
SPSA80, on the evidence. The title, the product reference and the body dimension all say 80 mm (3.15 in) and SPSA80, while the fourth bullet begins "The SPSA60 FJM Padlocks come with 4 unique European style keys" — a sentence lifted from the smaller model's listing. Everything else on the page agrees with the 80 mm (3.15 in) reading, including the stated 3 1/8 inch dimension, so the SPSA60 line is a copy error rather than an alternative. Confirm the size on the order page if the lock has to fit a particular hasp.
