The PD-108001 is a Delayed Egress Hook Lock from Lockwood that comes with 1000kg holding strength, Monitored and security option. The world famous and original V-Lock has been completely re-engineered to provide superior performance and reliability. The ES8000-S now incorporates a new motor and 1:19 ratio gearbox providing up to 65% additional preload capability and a higher locking force up to 10Kg. The electronic circuitry has also been completely upgraded to intelligently detect the locked state with “smart” retry function & uses on average 25% less peak current draw. Aside from some minor cosmetic changes, the lock body and overall footprint remains unchanged and is a direct retrofit for the original V-Lock. The ES8000-S has a high torque motorised bolt that moves from the vertical position to the horizontal state when locked. The bolt moves into the V shaped strike plate & allows for door misalignment of up to 7mm. The high torque motorised bolt can be concealed from view or surface mounted and has the world’s first fail-safe motor locking mechanism.
