Elk-924 Sensitive Relay to drive a solenoid

Hi all,
 
Looking at using a ELK-924 sensitive relay to drive a solenoid which will be used as a garage door deadbolt - http://www.ebay.com.au/itm/110884060252?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
 
Can anyone see any problems with this? The solenoid will retract when powered, so if my garage door is open a constant 12V will need to be applied to hold the solenoid open. Would there be any issues if say the garage door was open for extended periods of time?
 
Cheers

Solenoids come in 2 varieties.  Some are designed as continuous duty solenoids, and others are designed for intermittent duty.   Usually, the manufacturer will specify the duty level that they are designed for, but the eBay listing you linked to doesn't say. But from the applications listed (such as vending machines), I'd guess this one is for intermittent duty.
 
It's important to get a continuous duty solenoid if you think the door will be open for any length of time.

Is there a reason why you wouldn't want to get a strike and appropriate locking hardware instead of this? Definately only a bare illusion of physical security.
 
At $10 you get what you pay for and in actuality, this is just as strong as putting a screw across the door opening.

Thanks for the reply, I'll chek with the seller if its rated for continous duty.
 
Its for a "roller door", basically acting as a dead bolt in the roller track. Pretty much like this video on youtube : https://www.youtube.com/watch?v=D9hSp2FClIA

Far different solenoid and product...and to play devi's advocate, that mount appears that with enough upward force (provided not bolted through the L brackets) you could rip the entire thing off/out of the wood.
 
Really not a security item, more of a "warm fuzzy feeling" device.
 
While the door would probably be turned to shreds by using it, this is an application for a maglock.

Im just looking for a way to add a little more security so the door cant be forced open as easily. As with most options, nothing is foolproof, people will find a way around it if they so desire.
 
Maglock sell quite a few type of magnetic locks, which would you recommend?
 
Cheers
