Best credit card to use at Master Lock.

Home ImprovementOnline Shopping

Master Lock is a longtime American manufacturer of padlocks, combination locks, and security hardware, a category it has dominated since the 1920s and that now extends to bike locks, cable locks, and lock boxes sold through hardware stores and its own site. There is no Master Lock co-brand credit card, so purchases are best routed through a home-improvement category card, or a flat-rate cashback card if you would rather not track category bonuses for a lower-spend item like this.
