    The hole spacing did not match the old "Steelcraft" door handle it replaced, but that might be a good thing because the screws were installed to "new metal". Does the job.

    Reviewed in Canada on February 4, 2024

    So the screws in the box I have no idea what they are for so be prepared to get your own.

    Instructions what instructions? There's a picture on the box that contradicts the hardware included and slip of paper with half decent instructions for different products. So you better have a bit of DIY aptitude and just figure it out.

    I thought the packaging was scratched up but turns out it was manufactured with some decent scratches in it makes it look tougher I guess? If that's something that bothers you probably should pass.

    I pre drilled the holes and used some small self drilling hex washer screws to hold it in used a sharpie to mark where I needed the slot in the rail for the bar then drilled a top hole and a bottom hole and used a dremel and some files to finish the slot.

    The thing is beefy I'll give it that and the red handle is just cherry. No doubt it's going to rip my door apart before it will break.
    Just hope me and my wife can remember to lock out the opener when it's latched.

    5.0 out of 5 stars A mechanical lock perfect for my needs
    Reviewed in Canada on November 12, 2019
    Verified Purchase
    I purchased two of these mechanical locks after an attempted break-in into my garage where someone forced one side of the garage door open. These locks will definitely improve security - especially while you're away. Realizing I have two garage doors, and these locks only lock one side of the door, I decided to purchase two more (total of 4, installing a lock on each side of both doors). If you only use a single lock on a door, the other side of the door can still be forced upwards - something I wanted to completely prevent.

    The bolts included won't suffice for most doors. I purchased a bunch of metal screws, also from 鶹. However, you can buy these at your local hardware store as well for less. If you wish to order, here's a link: /gp/product/B00OKIVWIC/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

    Final note: These locks work well, and it is not the fault of the product if the user forgets to unlock the doors prior to operating their garage door opener. Having the garage door opener ripped out of the ceiling, while unfortunate, isn't the lock's fault - it did it's job. I would be more concerned if the lock broke in this scenario. Properly installed garage door openers won't rip themselves from the ceiling if they encounter resistance.
