Re: Safe Room Door Lock

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

It's 8" block wall with fully grouted cells and rebar. The door will be
mostly concealed including the hinges (dunno how but the guy is loaded so if
there is such a thing he will buy it). There won't be any visible door knob
or hardware so I think prying th door outward, even with only a 600lb mag
lock will be pretty darn difficult. Also, the perp will have to pass at
least 3 layers of an ADT alarm system to get to where the room is.

Yah ADT beat me to the remodel...but given they've already had 3 false
alarms since we've been there so dunno how long that relationship will last.
I met with the sheriff today and I asked him what zone ADT dispatched on and
he said they didn't give him any info...just the alarm dispatch...weird...we
always dispatch with a zone description. Ah well.

I hate prewiring for another company, but I am anyway. I know my prices are
more reasonable then their's would be.

|
| The force would be downward, not outward, with only a 1/2" insertion on 1
| 3/4" door. The best the perp could expect is to take a chunk out of the
door
| and only if the shank of the screwdriver didn't bend upward first.

| Lets think about this for kicks and giggles. A safe room is probably...
what
| 6'X8'? Maybe 8'X10'? and you want someone to get to a 15mph sprint in that
| distance. Riiiightttt! And why should they do this? To get out? Remember
the
| door swings out. All they have to do is hit the rex button. Why take a
| chance on injuring their shoulder? Next, a perp could take a 15mph run,
| which is questionable inside any structure, at it and if the door is
| installed properly, with or without a mag of any size most likely will
| bounce off the door and land on his ass. Why, because, again Robert, the
| door swings outward.
| Your propensity to quickly jump in and cast your opinions vastly
outweights
