Lock STABILUS Basi 6170-4000-BLAU luggage lock 21 mm combination lock blue

STABILUS Basi 6170-4000-BLAU is a compact 21 mm mechanical combination luggage lock in blue designed to secure suitcases, travel bags and cases. The lock uses a three-digit combination mechanism so no key is required, and its 21 mm shackle is sized to fit most standard zipper pulls and small attachment loops. Constructed for everyday travel and storage, the lock provides a simple way to deter casual tampering and reduce the risk of accidental opening during transit.

Advantages

The mechanical combination eliminates the need to carry or manage keys while offering quick access for users who know the code. The compact 21 mm shackle and lightweight body support easy installation on zipper sliders and small loops without adding significant bulk to luggage. The visible blue finish allows fast identification among several bags and provides a durable surface that resists everyday wear. The straightforward, all-mechanical design is inherently reliable and requires no batteries or electronics.

• Securing suitcase zippers during air, rail or road travel

How to use

Set and operate the lock by aligning the current factory-set combination to open, then attach the shackle through the zipper pulls or attachment loop and rotate to lock in place. To change the combination, follow the manufacturer’s mechanical reset procedure: open the lock, adjust the digits to a new code while in the reset position, and close to store the new combination. Store the chosen code in a secure place and test the new combination several times before travel to ensure reliable operation.

Usage recommendations

Use the lock as a deterrent to casual tampering rather than as a high-security device. Regularly inspect the shackle and body for wear before travel, avoid forcing the mechanism if it resists, and keep a record of your combination in a secure location. For valuable or high-risk items, combine with other security measures such as tamper-evident seals or carry valuables in locked, controlled compartments.
