Metal fetters

Technical Parameters: 1, screw-type metal anklet, the key is open to each other. 2. The outer surface of the metal anklet is smooth, without any defects such as angularity and Burr, and the connecting parts are smooth. Uniform paint film, no foaming and peeling and other phenomena. The left and right fetters of the metal anklets are of the same shape without obvious bending. Weight: 2.16 KG4, screw type, H: 85 mm, B: 90 mm 5, flexibility: The key can be inserted into the lock core of the metal fetters naturally, insert and pull smoothly, open and lock flexibly, each connecting part turns flexibly. 6. The locking fastener of the metal fetters shall be opened with a special tool. 7. Horizontal and Vertical Static tensile test of fetters: On the same set of metal fetters, the metal fetters with tongue and spring are under the locked condition, 2500N Longitudinal Static tensile force and 2500N transverse static tensile force were applied respectively, and kept for 30S, during which the metal fetters were not opened, and there was no permanent deformation or crack after the test. Durability: Metal fetters work no less than 3,000 cycles. Corrosion resistance: the Corrosion Resistance Grade of metal fetters is: Grade 7(spray cycle is 8 h)★ product provides the 2016 national security prevention alarm system product quality supervision and Inspection Center (Beijing) Ministry of Public Security Safety and Police Electronic Products Quality Inspection Center issued the test report. Implementation Standard: GA/T237-2005 metal fetters. Test number: No. 1630574.
