Keylex Quick Number Change Function: Easily change memory numbers!

Easily change the memory number with just key operations. No stress, it can be changed in a few seconds!

The Keylex series is continuously launching models equipped with the "Quick Number Change Function"! The "Quick Number Change Function" allows for the deletion and registration of memory numbers using the included key operation. The method of changing is very simple: to delete a number, just insert the key into the cylinder and turn it in the RESET direction; to register a number, press the desired number button and then turn the key in the SET direction. This eliminates the hassle of having to remove the Keylex unit from the door every time a change is made! It is recommended for places like hotels and vacation rentals where numbers are changed regularly. Additionally, in rental housing, changing the number when tenants change eliminates the need to replace the cylinder, thereby reducing costs. The method for changing memory numbers is also introduced in a video on the official Nagasawa Seisakusho YouTube channel! Please experience the new Keylex series with improved convenience!! 【Series with Quick Number Change Function】 　◇For Door Opening◇ 　　・4000 Series 　　・3100 Series 　◇For Sliding Doors◇ 　　・3100 Series *Double-sided specifications are only available in the 4000 Series.

In civil engineering work conducted near residential areas, schools, hospitals, and stores, consideration for noise and neighboring properties is essential. In particular, the sound generated during vehicle passage and the installation and removal of temporary roads, access routes, and heavy machinery work yards can be concerning. Hyper CLT sheets are civil engineering materials that utilize wood CLT. As wooden sheets, they can be used as alternatives to steel plates, for muddy ground measures, ground protection, heavy machinery scaffolding, and worker pathways. Due to the unique properties of wood, they provide a different experience compared to metal sheets, making them easy to recommend in sites where reducing metal noise and considering neighboring properties are priorities. Additionally, the texture of wood can soften the impression of the site, contributing to the creation of environments that emphasize environmental consideration and safety awareness. The 5×10 sheet weighs approximately 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to handle even with small machinery. They can also be utilized as a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A" for innovative ideas, safety measures, and neighbor considerations in public works. We also accept requests for materials and consultations for implementation.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can cause changes in the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
