At ESM, we believe exceptional products come from precision engineering and close collaboration with our customers. Acting on this belief, a dedicated team—led by our General Manager and joined by core engineers and sales executives—visited Guangdong on September 16, 2025. During this full-day onsite session, the team conducted an in-depth technical exchange with a key client, focusing on the newly launched 69100 Series European-style Lock Core Whale Tail Lock.

The 69100 Series Whale Tail Lock was the core topic of discussion. Developed to meet the demanding needs of high-end commercial and outdoor applications, the product integrates several key innovations:
Equipped with a high-precision cylinder that meets European standards, the lock provides strong keying capacity and minimizes key duplication risks. This significantly enhances anti-theft performance for increased security.
Inspired by the form of a whale’s tail, the handle offers both a distinctive visual design and a structurally reinforced build. The larger load-bearing area improves resistance to impact, forced entry, and harsh conditions such as road vibration.
Designed for toolboxes and compartment doors on trucks, RVs, and camper vans, the 69100 Series also serves as a secure locking solution for industrial enclosures and various equipment housings.


The General Manager of ESM noted, “This visit went beyond a typical meeting—it connected our R&D strengths with the client’s real operating needs. The insights gathered will directly influence the evolution of the 69100 Series and our overall product lineup.”
The client’s representative also shared positive feedback: “The professionalism and sincerity of the ESM team were impressive. Their willingness to visit and listen strengthens our confidence in continued cooperation. The design philosophy and security level of the 69100 Series align perfectly with our upgrade requirements and will add significant value to our end products.”
The session in Guangdong was more than a technical discussion—it was an important step in building mutual trust and aligning future development goals. Ningbo East Sea Machinery (ESM) remains committed to our principle of “Customer First, Quality as Our Soul.” We will continue delivering reliable locking solutions and elevating industry standards through proactive collaboration with customers worldwide.
