Re: [DML] door openers

["Rustproof" <Rustproof@xxxxxxxxxxx>]

I built my own door openers two years ago using a remote entry shaved door
kit I bought online for $60.00. It utilizes the large solenoids. It is very
well hidden and I used the existing leftover wires in the door. It has
worked flawlessly since and was almost a no brainer to modify and install.
All modifications are completely invisible. It does have a safety interlock
using a combination of doorlock position and key position. (Just a
tricked-out relay) They won't inadvertently open while driving even if you
press the remote button or in the event of component failure. (It will only
fail on the side of safety) You can even open just the right, left or both
door at once. The choice of actuator was purely happenstance That's what
came with the kit. I'm sure if the kit came with  motor driven units of
proper specification, it would work just fine too. This isn't rocket science
guys.  However, if you are not mechanically inclined or just plain lazy,
Darryl and  many other creative guys give you a nice set of options and they
stand behind their products. (Wouldn't it suck if there were only one brand
of tires or motor oil?) They design it, test it,  package it, guarantee it
and mail it to you. All you have to do is pay for it , follow the
instructions and not screw it up. Some guys like blondes and some guys like
brunettes...pick an actuator and  get it over with.
Either way, there's nothing more impressive than watching those doors glide
open by themselves! I recommend them highly!
