Liftmaster 41A6102 Power door lock

SERIOUS SECURITY FOR YOUR GARAGE DOORS!
Pair this accessory with a Liftmasrer jack shaft operator (3900 or 8500) and no one is breaking in without a lot of effort and noise. There simply is no way to open the door from outside without the proper remote control. Easy to install, 3 holes in the frame, perhaps only two if you are lucky, 2 screws and connect the wires to the operator. The operator does the rest, including proper sequencing. Don’t store your collector car without one for every door! I even got an insurance discount for using one.
