ViperX1 Gravity Gate Latch | One-Side Entry Keyed Lock | 2 Independent Latching Hooks Key Lockable One Side | Privacy Gate Gravity Latch | Vinyl, Wood, & Aluminum Gates - Black

Easy to install works great. High quality construction. Easy to open with full hands and lock is strong. Looks and fits perfectly. Little expensive but worth the peace of mind.

Very easy to install. Much more than I anticipated.

I was able to connect with customer support on the phone, the call started out seeming a little sketchy but I think the agent was just working from home. He had me send him a video of the problem and talked me through the fix. The lock has worked flawlessly since then. Great customer service. This latch and lock worked very well for a few months but today the locking mechanism and the latch failed. I had walked through the gate and locked it behind me but a couple of hours later the gate was open and my dogs were running around in the street. After I got my pets safely into the house I checked the lock only to fine that it was locked on the inside but the outside of the lock worked as if it was unlocked. Besides that, the gate opened at the slightest push, even when the prongs were lowered around the latch bar. I was able to make some adjustments so the latch would hold the bar again but I can’t make the lock function properly again. I’m assuming this lock isn’t really suited for a wooden gate as advertised. Wood swells and shrinks with the weather and this failure occurred at a change in seasons. Also, wooden gates are subject to more movement due to wind hitting the solid surface. Metal gates are often bars that permit the wind to pass through. The plastic bar that connects both sides of the locking mechanism don’t allow much of a margin of error therefore shrinking and swelling of the wood can cause the bar to fail and the gate lock to become inoperative. The lock came with screws that were too short to mount it well on a wooden fence but they would be adequate for a metal fence. I did replace them with longer, outdoor rated deck screws so that was my first clue that this lock was not made for a wood fence despite claims that it would work well for that application. I’ll be contacting support for assistance in repairing this problem and will update this review if they help me find a permanent fix for this issue.

The lock is amazing. The instructions are not as great BUT... I call the support as I couldn't lock the latch and got a technician that was very helpful. Here are the missing instructions: 1 - on the latch side... make sure the key is in the OPEN position before installing it and start with this side FIRST with no key in the lock. 2 - push side and still WITHOUT the key in the lock... let's position the rod. The rod turns 180°. You need to find the middle position so that you can turn 90° left and 90° right. Let's call that the 0° position. You can only install the push side when it is on the 0° position. Once in the 0° position, slide it into the hole to connect with the latch side (assuming the length of the rod has been adjusted already). Rod length: make sure the rod has the proper length. Easy to figure out... look at the EXACT size of your post and report that value on the rod ruler (in inches or mms). For instance if your post like mine is thin and measures 38mm then cut the rod just before the 40mm mark. You know that the length is correct when you install the two parts and the two latches (looks like viper fangs) are fully sunk (like you can't see the tip of the fangs) Again, amazing support from Safetech.

THIS LATCH IS ABSOLUT JUNK!!!! DON'T WAIST YOUR MONEY. The internal guts are all plastic and the instructions don't even make good toilet paper. In two months the lock will not stay locked. Push hard enough on the outside lock and it unlocks everything. Now I have a 1/2" hole drilled through my fence post AND I'M OUT $88.

easy enough to install and love that it has opening and locking options on both sides but because it's a bit cheaply made it is often not able to engage the locking teeth unless VERY gently closed. The teeth get stuck in the UP position and even though it is addressed on the troubleshooting section of the manual, it is not always fixable the way they instruct. I often have to pull the teeth down with my fingers. I just wish it was more reliable. Also, the lock mechanism was conveniently able to be put on one or the other side, but the lock arm was NOT...so basically negates the versatility of the lock mechanism positioning. Overall, if it worked exactly as it was supposed to it would be a really really great piece, but unfortunately with mostly plastic parts it just is not that reliable.

Wonderful lock. Can lock and access on either side defense, which is excellent. Was not easy to install at all, though directions for shaft that goes through fence were not great but eventually, I got it to work and I’m very happy with it.

Had to replace my standard lock on my pool gate because the door sags so it would not latch (lock) properly, no matter how many times I fixed the sag. This latch is awesome. Love the way it clicks into the door and how easy it is to open from the other side (I bought the 2 sided lock). Really simple to install. Easy to open and close, love that I can use a key to lock it too. Highly recommend.

Great lock. But parts not available in UK. Only place i found was in Western Australia. Be aware that the plastic rod that connects to each side of the gate wears easily until it is not long enough to activate the gates mechanism. (Wears when touching metal components). The company in WA are very accommodating. So either online payment (expensive charges) or late night waiting for OZ to open.

Worth the money, very heavy duty, works perfectly for a huge metal gate.

I bought a similar one from a hardware store and it was rubbish. hard to get it to lock, easy to force open. I then got the slightly cheaper one from Amazon, installed in on another gate and found it was twice the quality of the hardware store one I bought a second one to replace the hardware store latch. I like that it is easy to disassemble to re pin to your own key, the double 'fang' to catch the gate bolt also means that its if everything isnt perfectly aligned, it will still lock.

Really easy to install....just make sure your measure and cut on the connecting bar is precise. Otherwise looks and works well.

Works like a charm And easy to assemble
