Master Lock Co 643D Aluminum Combination Padlock

Product Description

The MASTER LOCK CO 643D is a compact aluminum combination padlock designed for luggage, bags, and light-duty security applications. The body measures 1-9/16 inches wide and is constructed from aluminum for a balance of low weight and weather resistance. The 7/8-inch steel shackle provides solid cut resistance for travel and storage use. A user-settable combination eliminates the need to carry a key, making this a practical choice for travelers, locksmiths supplying travel accessories, and facilities staff managing small lockout needs.

This padlock is sized for luggage hasps, soft-sided bag zippers, and similar light-duty applications. Its aluminum construction keeps weight minimal, which matters for checked or carry-on baggage. The user-settable combination feature makes it suitable for bulk distribution in hospitality, facilities management, or travel retail environments. Each unit ships individually carded, and the package contains 4 units per pack.
