Between 2010 and 2014 the TSA reported more than $2.4 million in missing items at American airports alone. 25% of these thefts happened in the baggage pick-up areas. ♦ TSA Locks Work as an Excellent Deterrent. With so many bags unlocked, other people present and limited time to work in, thieves will pass locked bags by in favor of easier unlocked targets.♦ An Alloy Body Designed for Tough Work. SureLock uses a 100% alloy body which is built with the stress of airport handling in mind. We back this up with a lifetime warranty which covers damage caused by baggage handlers and TSA inspectors. ♦ Know if You’ve Been Inspected Right Away. There’s nothing worse than getting to your hotel and discovering that the TSA has lost an important item when inspecting your luggage. SureLock’s inspection indicator will let you know if the luggage has been opened right away so you can deal with any problems while you’re still at the airport. Review: Buen producto - Buenos material, terminado solo un poco pesado. Review: Nice metal locks - I’m happy to feel the weight of these and really like that they’re not made of cheap plastic. They’re easy to set and should hopefully help deter thieves. (if only because they choose an easier target without locks. Lol) ## Features - THE MOST DURABLE LOCK ON THE MARKET. SureLock uses an ultra tough alloy body to protect our locks from the harshest of baggage handling. Our hardened stainless steel internal lock mechanisms won't rust or freeze up even after years of use. Put our locks to the test. We back them with a complete money back guarantee. - PEACE OF MIND WITH AN INSPECTION INDICATOR. Know if your luggage has been inspected as soon as you pick it up at the airport with our pop-up inspection indicator. If the TSA has opened your luggage, a button will pop out of the top of the cable lock. You'll know to double check your luggage to make sure nothing has gone missing while you're still at the airport instead of at your hotel or final destination. - EASY SET COMBINATION MECHANISM WITH FOUR DIGITS. Setting your combination literally takes less than ten seconds and the use of four digits means that your combination is harder to crack and easier to remember. In addition to this, you can change your combination as many times as you would like. - A SECURE LOCK WHICH WORKS WITH NEARLY ANY KIND OF LUGGAGE. The standard size of the steel shackle loop on luggage locks is 21.67mm. We decided to lengthen the shackle on these locks to 25.67mm. This allows them to better fit hard cases such as Pelican or gun cases. - EASY TO READ DIALS. SureLock uses a white numeral on a black background for our combination dials. These high contrast dials make reading your combination a breeze. No more squinting or searching for glasses as you try to open your locks. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076NQ87X1 | | Additional Features | TSA Approved | | Best Sellers Rank | #99,922 in Bags, Wallets and Luggage ( See Top 100 in Bags, Wallets and Luggage ) #1,068 in Luggage Locks | | Brand | SURE LOCK | | Brand Name | SURE LOCK | | Colour | 17021ALL COLOUR | | Control Method | Touch | | Controller Type | Combination control | | Country of Publication | USA | | Customer Reviews | 4.6 out of 5 stars 4,061 Reviews | | Included Components | lock | | Item Dimensions | 17 x 51 x 25 Millimeters | | Item Weight | 79.38 Grams | | Item dimensions L x W x H | 17 x 51 x 25 Millimeters | | Lock Type | Combination Lock | | Manufacturer | SURE LOCK | | Manufacturer Part Number | 43235-167706 | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model Name | TSA17021 | | Model Number | TSA17021 | | Number of Pieces | 1 | | Product Finish Type | Painted | | Recommended Uses For Product | securing luggage, lockers, toolboxes, gun cases, and golf cases | | Shape | Rectangular | | Special Feature | TSA Approved | | Style Name | Fashionable | | UPC | 646648185169 | | Unit Count | 4 Count | ## Product Details - **Brand:** SURE LOCK - **Special Feature:** TSA Approved - **Lock Type:** Combination Lock - **Item dimensions L x W x H:** 23.9 x 13 x 2.5 Centimeters - **Material:** Stainless Steel ## Images ![SURE LOCK TSA-Approved 4-Digit Resettable Combination Lock with Open Alert, Easy-Read Dials - for Luggage, School Lockers, Gym, Office, Toolbox & Security Cases (Available in 1/2/4-Pack), 17021ALL - Image 1](https://m.media-amazon.com/images/I/61dtiNXFwmL.jpg) ![SURE LOCK TSA-Approved 4-Digit Resettable Combination Lock with Open Alert, Easy-Read Dials - for Luggage, School Lockers, Gym, Office, Toolbox & Security Cases (Available in 1/2/4-Pack), 17021ALL - Image 2](https://m.media-amazon.com/images/I/61sZG8I22EL.jpg) ![SURE LOCK TSA-Approved 4-Digit Resettable Combination Lock with Open Alert, Easy-Read Dials - for Luggage, School Lockers, Gym, Office, Toolbox & Security Cases (Available in 1/2/4-Pack), 17021ALL - Image 3](https://m.media-amazon.com/images/I/61QEQJygnsL.jpg) ![SURE LOCK TSA-Approved 4-Digit Resettable Combination Lock with Open Alert, Easy-Read Dials - for Luggage, School Lockers, Gym, Office, Toolbox & Security Cases (Available in 1/2/4-Pack), 17021ALL - Image 4](https://m.media-amazon.com/images/I/7123AAFgPwL.jpg) ![SURE LOCK TSA-Approved 4-Digit Resettable Combination Lock with Open Alert, Easy-Read Dials - for Luggage, School Lockers, Gym, Office, Toolbox & Security Cases (Available in 1/2/4-Pack), 17021ALL - Image 5](https://m.media-amazon.com/images/I/611QC0eUV9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buen producto *by L***S on 17 October 2025* Buenos material, terminado solo un poco pesado. ### ⭐⭐⭐⭐⭐ Nice metal locks *by J***Y on 19 October 2024* I’m happy to feel the weight of these and really like that they’re not made of cheap plastic.
