LONG THROW vs SHORT THROW (deadbolt)
There is a misconception that a deadbolt used on vehicles must have a long throw (stick out and into a recepticle) in order for it to work properly, not so.
The AutoBolt SS along with the original Auto Bolt were specifically designed for a short throw to take advantage of leverage to the device and avoid excessive size and bulk. The longer a bolt sticks out the more leverage advantage you are giving to the would be thief in applying pressure to the end of the bolt and bending it sideways and causing damage to the unit. This tends to show up when a door is accidentally locked and the door slammed shut. One of two things happen or both. 1. the loss of leverage advantage allows pressure on the extended end of the bolt and often causing damage to the linkage or drive mechanism of the unit. This often times prevents the bolt from retracting into the door and requiring the need to push it back into the door in order to be able to close the door. That also usually results in the bolt being stuck or jammed into the unit to be rendered ineffective for future use. The long throw often allows damage to the vehicle sheet metal as well, denting the metal and chipping away the paint. The plus benefit is that it would take a thief with a big tool to defeat the long throw.
On the other hand, the short throw does not stick out far enough to damage the vehicle via denting the sheet metal or chipping the paint as the bolt remains inside the door frame and out of harms way. The Ramp Latch tm developed for the AutoBolt SS is designed to gently push the bolt (the only moving part on the SS) back into the housing without clanging the door or especially damaging itself. Making the AutoBolt SS virtually indestructible! Also see the test results for manual extrication from a vehicle with the bolt extended (in case of an accident when using the AutoBolt on the front doors for complete protection) The AutoBolt SS does not impede or impair a manual extrication rescue! Rather than using a long throw and giving up leverage advantage, if the door gap is more than 1 inch, it is recommended to use a space (metal or nylon) to bring the ramp latch out to the short throw bolt and maintain leverage advantage. It’s not how deep the bolt goes, but ow well you dissipate the force being applied.
Back to the leverage advantage. The further a bolt sticks out of the unit, the more susceptible it becomes to damage from pressure on the end of the long throw, granted that shouldn’t happen, but it can. The more pressure put on the end of a long throw, the more (multiplied) pressure on the unit or housing. The best way I can explain it, is if I give you a pencil and ask you to break it. You probably could snap it into with ease. However, if I give you a 1 inch piece of pencil and ask you to break that in two, you would probably spend a lot of effort and energy into it and transferring that energy back and forth between your hands and not be able to break that 1 inch piece. That is how the AutoBolt SS retains its leverage advantage and trnsfers whatever energy a thief might put on the short throw and transfer it into the housing which passes it on to the sheet metal of the vehicle surrounding it. For a demonstration of how important leverage can, look a the strength test video of the original Auto Bolt made of high impact plastic and steel inserts. https://youtu.be/O4zHGKhLjXY That tiny ½ inch plastic bolt was able to defeat two-2,000 lb tie down straps that were actually pulling the sheet metal right off the door frame! We like to say “small…..but mighty”. That’s the power of leverage to your advantage.
The AutoBolt SS is fast becoming known as the sexy vehicle security for its appealing looks and smooth function. It is strong, simple (one moving part), effective Greg the AutoBolt Guy
