Arlai 4" Stainless Steel Latch Lock Padlock hasp Set, with Screws and Padlock, Your Own Fence Locks gate Lock, for shed Locks with Keys Lock hasp Set

What you get and where it fits

I installed this Arlai hasp-and-padlock set on a backyard shed door that needed a simple closure—something more secure than a hook-and-eye, but not a full deadbolt. It’s a compact kit: roughly a 5-inch stainless hasp, eight mounting screws, and a small iron padlock with three keys. The pitch is straightforward: a quick, affordable way to add basic lockability to a door, gate, cabinet, or locker.

Right out of the package, the hasp looks clean and fairly well finished. Edges are smooth, the hinge swings freely without binding, and the staple (the loop the padlock goes through) is sized for small to medium padlocks. The included padlock is compact—think “locker lock,” not “high-security.” This is squarely a light-duty solution that prioritizes convenience and price.

Build and materials

The hasp is stainless steel, and it behaves that way in real use. After weeks outdoors, mine hasn’t shown rust or staining, even after a couple of light rains and morning dew. The gauge isn’t heavy, but it’s not paper-thin either—appropriate for a 5-inch hasp intended for sheds, cabinets, and utility doors. The hinge doesn’t wobble excessively and closes flush with the staple aligned.

The padlock is a different story. It’s iron, basic in design, and not built for weather. It operates smoothly out of the box, and the keying is fine, but it doesn’t have the corrosion resistance or cold-weather tolerance I’d want for permanent outdoor duty. For indoor use (closets, lockers, cabinets), it’s perfectly serviceable. Outdoors, I saw surface spotting and one freeze-up during a cold snap that required a bit of de-icer to free.

In short:
- Hasp: decent stainless, good for indoor/outdoor, light-duty thickness.
- Padlock: functional but not weather-resistant; best kept indoors or replaced for exterior use.

Installation experience

Installation is as simple as it gets. Mark the door leaf and frame, pre-drill pilot holes, and drive the included screws. A couple of tips made the install cleaner and more secure:

• Use longer screws. The included screws are short and fine for thin cabinet faces, but for a shed or exterior door, longer stainless screws (I used #8 x 1-1/4-inch) bite deeper and resist prying better. If you’re mounting to softwood or thin siding, consider through-bolts and washers on the inside.
• Align so the hasp covers the screws. The hinged leaf should cover the mounting screws on the staple plate when the hasp is closed; that’s what prevents someone from simply removing the staple plate.
• Pre-drill carefully. The metal plates have little tolerance; if your pilot holes drift, the hasp can bind. A scratch awl to mark centers helps.
• For exterior installs, seal the holes. A dab of exterior-grade sealant in the pilot holes reduces water ingress and swelling.

Installed on a simple plank door over a 2× frame, the hasp sat flat, closed squarely, and didn’t rattle. The footprint is narrow (about 1.25 inches wide), so it fits on skinny stiles and cabinet faces where chunkier hardware won’t.

Day-to-day performance

As a daily-use latch, it’s fuss-free. The hinge opens and closes smoothly and the staple lines up consistently with the padlock shackle—no fumbling or misalignment after a few weeks of use. The stainless finish wipes clean and doesn’t snag clothing or gloves. On my shed, opening and relocking with one hand was easy.

Outdoors, the hasp has held up very well to moisture. The padlock, as noted, is the limiting factor. In damp, cold conditions, iron padlocks tend to take on moisture, and freezing temperatures can lock them up. A dry Teflon or graphite-based lubricant helps; oil-based lubricants can gum up in the cold. If you plan to use this set outside regularly, I’d upgrade the padlock.

Security reality check

No small hasp-and-padlock combo is a silver bullet, and this one is meant for deterrence, not high security. Judged by that standard, it does its job. It keeps kids out of a well house, discourages casual snooping in a storage cabinet, and raises the effort needed for opportunistic theft from a shed.

A few sober points:
- The hasp thickness is light-duty. It resists casual prying, but with enough leverage and poor mounting, it can be defeated.
- The included screws are short. Longer, harder, or tamper-resistant screws materially improve resistance to prying.
- The staple accepts small to medium shackles. A 30–40 mm brass or stainless padlock fits well. Discus-style locks may not seat properly given the narrow hasp.
- Your door and frame matter. Mounting into solid framing or a backing plate makes a bigger difference than the metal gauge alone.

If your goal is to secure high-value tools or deter determined intruders, this isn’t the right class of hardware. If your goal is to add a modest, reliable lock point to something that previously had none, it’s right in the zone.

Best uses

• Indoor: lockers, cabinets, utility closets, storage trunks.
• Semi-protected outdoor: sheds, well houses, fence gates where the lock is under an eave or checked regularly.
• Temporary or budget-conscious setups where convenience and speed matter more than brute strength.

What I’d change

A few small tweaks would elevate the set without changing its identity:
- Include longer stainless or security Torx screws. It’s the easiest upgrade and improves real-world security.
- Upgrade the padlock or offer a weather-resistant version. Even a basic brass body with a stainless shackle would cope better outside.
- Slightly thicker hasp leaf or reinforced staple. A modest bump in gauge would add confidence without making installation harder.
- Clarify the stainless grade. Knowing whether it’s 304 or 201 helps set corrosion expectations in coastal environments.

Practical upgrades

If you’re installing outdoors, I recommend:
- Replacing the padlock with a 40 mm brass or stainless model, preferably weather-rated. A covered shackle design resists bolt cutters and moisture.
- Using longer stainless screws or through-bolts where possible.
- Adding a backing plate on thin doors to resist tear-out.
- A periodic shot of dry lubricant on the hinge and lock cylinder.

These changes are inexpensive and transform the set from “basic” to “appropriately robust for light outdoor duty.”

Value and alternatives

The value proposition here is strong: you get a serviceable stainless hasp, all the fasteners, and a working padlock with keys in one package. If you only need indoor cabinet-level security, it’s a tidy, low-hassle solution. If you’re thinking exterior, factor in the cost of a better padlock and upgraded screws. Even with those add-ons, you often end up spending less than piecing together a premium hasp and lock separately.

If you know you need heavier-duty hardware—thicker hasp leaves, hidden or shielded staples, or compatibility with high-security discus locks—look toward larger, reinforced hasps and weatherproof padlocks from pro-grade lines. They cost more, and installation can be fussier, but the jump in security is real.

Bottom line

This Arlai hasp-and-padlock set is a compact, easy-to-install way to add lockability to doors and cabinets that don’t need heavy-duty security. The stainless hasp holds up nicely outside, the action is smooth, and the footprint fits where bulkier hardware won’t. The included padlock gets you up and running, but it’s the weak link outdoors; swap it for a weather-rated brass or stainless lock if you’ll be in the elements.

Recommendation: I recommend this set for light-duty applications, especially indoors or semi-protected outdoor spots, with the caveat that you should upgrade the screws and padlock for exterior use. It’s a good-value starter kit that, with a couple of thoughtful tweaks, becomes a dependable everyday latch solution. For high-value storage or high-risk areas, step up to heavier hardware.
