This TSA-approved luggage lock bundle contains two Master Lock 4688D set your own combination locks, available in red and blue. Both locks feature durable metal bodies measuring 1-3/16 inches wide, with 1/8-inch diameter flexible steel shackles covered in vinyl for resistance to baggage handling abuse. The 1-1/2 inch shackles securely fasten luggage, backpacks, storage cases, and more while allowing TSA agents to inspect and relock bags when needed. These Master Lock bundle components complement each other through their matching high-quality construction and TSA-accepted status, providing flexible color options to organize and identify your locked baggage. Pairing red and blue allows travelers to color code locks for different bags or family members. The included Master Lock lifetime limited warranty provides added peace of mind on both bundle locks.
