Fitting a vsb door opener is really quick and easy.
Just for fun I timed myself fitting this door installation and it took less than 4 minutes.
8 screws to suit the timber you’re attaching it to (we use 25×3.5mm)
a short piece of string.
First mount the door.
The lower screws form the bottom door stop that the door must rest against when it is closed. Attach the first runner with the bottom screw, straighten the runner and fit the top screw. Rest the door on the screw and position the runner on the other side and attach with a screw in the bottom hole. Now lift the door up to the top to check that it slides freely and fit the last screw in the top of the runner.
Now attach the cord from the vsb using a short piece of cord. The easiest way is to remove the door from the runner so you can work with it on the flat but this is not essential. Why use an extra piece of cord? You could use the cord that is coming out of the VSB but you need to maintain the knot that actuates the stop switch inside the unit and this is actually quite fiddly to do.
Now remove the lid of the VSB so you can access the mounting holes which are behind the each of the lid screws. Re fit the door into it’s runners and hold the VSB unit so the door is hung in the open position.
The trickiest part of installing the VSB is getting the screws to come out of the back of the unit without falling off the screwdriver! I find the best way is to stick the screw to the screwdriver and then, swiftly and in one movement, aim the screw into the back of the hole. Licking the head of the screw is often enough to stick the screw to the screwdriver.
Once you have one screw in you can level the box and then fit the other 3 screws.
Your vsb door opener is now ready for the batteries to be fitted, tested and the lid refitted
