Cheap knock-off

Reviewed in Canada on 22 July 2018

Colour Name: Brushed ChromeVerified Purchase

This version is a cheap knock off of the version you might find elsewhere. I've had these types of locks in previous homes and those previous ones operated much more smoothly. This one is poorly machined and not as easy to quickly open or close. It also weighs less than half as much and seems to be made from a cheaper alloy, so I question how much force it could withstand before snapping.

Some difficulty installing on metal frame...

Reviewed in Canada on 20 December 2018

Colour Name: Brushed ChromeVerified Purchase

I installed one of these on a wood frame with zero issues using the long screws. All the reviews are right - it's excellent, very competitively priced and it's not going anywhere. As to my installation on a metal frame, well that proved more problematic. The instructions suggest that the product can mount to metal frames but it doesn't provide much in the way of specific instruction. I assumed that the short screws included in the package were sheet metal screws intended for metal jambs.

They didn't quite work. The end result was that the lock wasn't firmly affixed to the frame (it wiggled and moved) but the screws could not be tightened any further.

Seems like either the countersink in the product doesn't match the profile on the screw head or the screws run out of thread before being completely secured, or both. Not a problem with wood jambs but definitely a problem with metal. I fixed this problem in my case by placing a spacer plate I quickly hacked up between the product and the door jamb to move the product away from the jamb - fortunately I had enough of a gap to accommodate. With this spacer in place, the screws could be firmly tightened and the lock mounted securely.

Awesome design, secure and easy to install

Reviewed in Canada on 1 May 2018

Colour Name: Brushed ChromeVerified Purchase

Awesome design. Extremely secure. You'd have to crash a car through my front door to open this.

We have double front doors design. So I've installed this upside down at the top of the non opening door. So along with the two pins the door already had, with this new U lock, it's seriously secure now.

The secure-ness comes from the fact that the screws are perpendicular to the direction of forced entry. If it was parallel (like if you were able to pull the screws from the head out) then yes one can use force to break loose this lock.

But being perpendicular to the force of entry , it is impossible to break this lock without actually unlocking it yourself from the inside. Now the danger is, you may forget to unlock this and exit through the garage door (and close it), now you cannot enter through your front door !! HAHA.

Easy to install too. Did it on my first try.
