In the world of automatic gate openers, a common new feature you'll see is as a gate is closing it will slow down for the last few feet instead of slamming shut. The slow down feature not only dampens the sound of the gate closing, but also takes stress of the gate and gate opener components.One problem with this feature is the lack of momentum as the gate closes, it reduces the amount of weight hitting the lock to below the weight needed for the gate to fully close and lock. Instead, the gate latches rest on top of each other without fully locking, leaving your gate unprotected against forced entry and wind. What separates the Estate Swing lock from the rest of the competition is that it requires less than 1 pound of weight for the gate to lock. While other locks require approximately 10 pounds of weight, which is no longer generated from the momentum of the gate because of the slow down feature. Another benefit of the Estate Swing lock is the unique pivot design reduces power consumption. The older model locks require 3 amps to pull the latch open because they pull back on a direct linear path. The Estate Swing lock requires less than 1 amp because it works on a swivel, making the pulling action much easier. The reduction in power required for the lock means less strain is put on the system as a whole as power is distributed through the motor and control board. Since less power is then required from the system, you can reliably active and run the motor, power accessories, get a longer life span from battery systems, and will not stress the circuitry of the control board of the gate opener.
