Master Lock Combination Padlock Outdoor Brass Long Shackle 2-Pack 175LHEC2

The Master Lock 175LHEC2 combination padlock two-pack offers a keyless security solution designed for indoor and outdoor enclosures like sheds and exterior gates. It targets property owners who need extra reach from a shackle without dealing with physical keys that can be lost or misplaced. By combining a generous opening with dial-based access, this set aims to simplify security around residential and light commercial perimeters.

The central feature of this model is the extended 2-1/4-inch (57mm) hardened steel shackle, which provides clearance for wide hasps, thick gates, and irregular locking points. The 5/16-inch (8mm) shackle diameter pairs with hardened steel construction to deliver resistance against cutting. Underneath, the 2-inch (51mm) wide solid lock body is engineered for structural strength and weatherability, making it suitable for exterior installations exposed to the elements.

Instead of carrying keys, each unit uses a user-settable four-digit combination mechanism that arrives preset to 0-0-0-0. The package includes a dedicated combination change tool to reset the digits, and the process is detailed in the accompanying user manual. Having two identical locks in one package allows users to protect multiple gates or outbuildings while standardizing their access method.

Because combination changes require the included change tool, you must keep track of that small accessory or you may not be able to update your code later. In addition, the 5/16-inch (8mm) shackle thickness means it cannot slip through smaller hasps, locker holes, or narrow fixtures. The listing also does not mention whether both locks can be synced to share identical codes or whether they operate completely independently, nor does it specify any key override mechanism.

Verdict: This Master Lock two-pack is an effective, practical choice for homeowners and facility managers securing outdoor sheds, gates, or perimeter barriers that demand extended shackle clearance. If your locking points require a generous 2-1/4-inch reach and you prefer dial-based keyless entry, this pair fits the bill cleanly.

A great fit if you:

• Need to secure exterior gates or garden sheds that feature thick mounting hardware or wide latch openings requiring extra clearance.
• Want the freedom of keyless access so family members or coworkers can open storage areas using a memorable four-digit sequence.
• Prefer a bundled set of two padlocks to secure separate access points across a single property without purchasing individual units.

Consider something else if you:

• Require padlocks for lockers or storage boxes with latch holes that cannot accommodate an 8mm thick shackle.
• Prefer changing your combination by hand on the fly without needing to store or locate a specialized reset tool.

Confirm on the listing:

• Measure the hole diameter on your gate latch, shed hasp, or chain links to confirm they accept an 8mm (5/16-inch) shackle.
• Check the spacing across your gate or door fixtures to ensure the 2-1/4-inch shackle length and 1-inch shackle width provide sufficient reach.
• Verify that the package contents explicitly state the inclusion of both locks along with the combination change tool before finalizing your order.

How to compare your options: When evaluating padlocks for gates and sheds, focus primarily on shackle clearance, material hardness, and locking mechanisms. A long shackle like this model's 2-1/4-inch vertical opening solves clearance challenges on deep latches where standard short shackles fail to close. If your gates are outdoors, ensure the lock body specifies solid weatherable materials and hardened steel components to handle everyday exposure and deter basic cutting attacks.

• Keep the included combination change tool in a safe, labeled indoor drawer alongside the user manual so you can reset your digits whenever needed.
• Test your newly chosen four-digit combination multiple times while the shackle remains open before snapping the lock shut onto a shed or gate.
• Spin the dials thoroughly away from your selected code every time you lock the shackle to ensure the mechanism is fully scrambled against unauthorized viewers.
• Inspect the dials and lock body periodically to wipe away loose outdoor dirt or debris as recommended in general lock care guidelines.
