Garage door lock bolt

[DXP55]

I have a fully retractable garage door to which I have put a Liftmaster opener.

The only niggle I have is bottom of door isn't fully secured because of the operating arms and springs - in other word you can pull bottom of door out a few inch's but top is fully secured by electric opener.

What I need is a electric drop bolt to fix centrally on bottom of door with drop bolt facing down - The Lifter has a 12v output on action so the drop bolt needs to be spring loaded to push it into a plate on floor and retracted on operating button.

I have spent a good while on google and found some but they seem to be wrong way round for me - in other words power on to lock - I need power on to retract bolt.

Has anyone seen one or know of something that would do the job.

Thanks

Dave

Google solenoid bolts.

More likely to find something suitable.

Things like this.

Thanks for looking but I had seen those earlier and they are not suitable - seems I needed gate bolt's.

However the problem has been solved by Garage door man who came to look at my door.

Seems new doors have a fitting worked by action bar of opener that pulls wire which opens two locking bars at base of door.

So new door to be fitted. - At last getting rid of old wonky door
