Whether you are looking to secure your GPS or your precious Doubletake Mirrors, this lock knob will add a layer of protection for a few bucks.
 
The knob consists of a 1/4"-20 female threaded security knob and a knob key.
It can replace all finger knobs on our arms and mounts.
 
At a fraction of the cost of currently available keyed locking knobs, the additional peace of mind and tamper resistance comes at a very affordable price.
 
It is the perfect accessory for keeping your mounted accessories safe from theft and tampering.
