Guliffen Outdoor Combo Lock – Weatherproof 3/8 Inch Shackle, 3-Pack

Secure, weatherproof protection for outdoor spaces

The Guliffen Outdoor Combo Lock is a compact, heavy-duty solution designed for sheds, gates, fences, and trailers. Sold as a convenient 3-pack, these disc locks share robust construction and a customizable 4-digit code, balancing security with everyday practicality.

Rugged build for real-world durability

Crafted with a hardened steel shackle and a zinc alloy body, these locks emphasize strength without adding unnecessary weight. The weatherproof design helps shield against moisture and temperature changes, making them reliable companions for outdoor storage and access points across seasons.

• 2-3/4 in wide lock body for a balanced, unobtrusive profile
• 3/8 in diameter shackle provides a snug fit on common hasps
• 4-digit combination offers 10,000 possible codes for customization
• Simple, user-friendly code setting and resetting process
• Designed for outdoor use on storage units, gates, sheds, trailers, and garages

How to set your own combination

Start from the default 0-0-0-0, then follow a quick sequence to personalize your access. A small reset screw is moved from A to B to enable the new code, and returning it to B saves the change for future use.

1. Open at the default 0-0-0-0
2. Move the reset screw from A to B with a clip or screwdriver
3. Rotate to your chosen 4-digit code
4. Move the screw from B back to A to save the new code

Practical uses and what to expect

Use cases span from routine maintenance visits to off-site deliveries. The 3-pack setup lets you secure multiple access points with either identical or distinct codes, depending on how you configure the locks. While no system can guarantee absolute security, the combination approach reduces the need for key management and offers flexible access control.

• Secure storage units behind gates or porches
• Gate and shed protection for routine upkeep or contractor access
• Trailers and equipment enclosures that travel between locations

Note: Before purchasing, verify that the shackle size fits your intended application. The 3/8 inch shackle is a common fit for many setups but may not suit every requirement.
