4-Pack 4-Digit Disc Combination Padlocks with 3/8" Hardened Shackle

Product description

What’s in the box: a set of four disc-style combination padlocks, each with a keyed-outless 4-digit mechanism for up to 10,000 possible codes. They arrive ready to program and use, giving you four independent locks for multiple points of access.

Construction and materials: each lock features a 3/8" (9.5mm) hardened steel shackle and a rounded, shielded body designed to limit shackle exposure to bolt cutters. The locking mechanism is housed on a solid brass internal cylinder to resist corrosion and maintain smooth operation in damp or variable weather conditions.

Dimensions and fit: the padlock body measures approximately 2-3/4 inches (70mm) across, with the hardened shackle sized at 3/8 inches (9.5mm) diameter. These proportions make the locks suitable for standard hasps, storage unit latch holes and common chains; note that the shackle thickness may require a sturdier chain in some setups.

Security features and use: the round shielded profile reduces leverage points for cutting tools while a pick-resistant design helps guard against manipulation. The 4-digit, keyless combination is straightforward to set and change, allowing temporary codes for guests or staff without issuing keys.

Support and recommendation: the locks come with a 12-month warranty and access to customer support if you encounter issues. Before installing, measure your latch or hasp and the chain opening to confirm a good fit and ensure the shackle diameter works with your hardware.

Pros

  • Keyless 4-digit combination with 10,000 combos
  • Hardened 3/8" steel shackle and shielded body
  • Brass cylinder for corrosion resistance

Cons

  • Shackle may need a thicker chain in some setups
  • Resetting the code can be awkward on certain units
  • Occasional defective unit reported

VerdictThese four disc-style combination padlocks deliver robust, keyless security for a variety of outdoor and indoor uses. The hardened 3/8" shackle and round shielded body reduce exposed metal and improve resistance to bolt cutters. The 4-digit mechanism provides ample combinations and convenient keyless access, though a few users report a fiddly reset on some units and the shackle diameter may requir
