master lock combination

Master Lock combination locks use several styles: preset numeric dials (commonly 3‑digit and 4‑digit), 4‑dial numeric mechanisms, and set‑your‑own word combinations found on some luggage‑style locks.

Listings highlight features that increase cut resistance and durability: hardened steel shackles, solid or metal lock bodies, stainless‑steel covers, braided steel cables, and protective vinyl coatings to protect surfaces.

The listings show 3‑digit and 4‑digit numeric combinations, 4‑dial mechanisms, and some set‑your‑own word combinations for luggage locks. A 4‑digit numeric option provides thousands of possible combinations.

Most listings describe locks for indoor applications such as gym and school lockers. At least one listing explicitly calls out both indoor and outdoor use (for lockers, gates, etc.) and notes a solid body for improved weatherability.

Shackle diameters range from about 1/8 in (3 mm) up to 5/16 in (8 mm), with common shackle lengths around 3/4 in (19 mm) to 1 in (25 mm). The cable option is listed at about 3/8 in (10 mm) diameter and 5 ft (1.5 m) long.

Several listings cite features to aid dialing: soft‑touch dials, dial grip points or textured dial edges, ergonomic designs, and no‑slip grips for more accurate dialing.

Most listings use wording such as “Lifetime Limited Warranty,” and a few use phrasing like “Lifetime Guarantee.”
