Guardian Drain Lock Dome-D-Lock Commercial Floor Sink Locking Dome Strainer For Restaurants, Hotels, Kitchens, Managers To Prevent Clogs and Pipe Damage 3 Inch

Noticed that rats were coming inside my home via the drainage hole which had no cover. This totally stopped it. I highly recommend!

I really needed to replace a damaged guard. This one did the trick and it was a perfect fit

Looks like a good product. Everything is like described. Only thing, probably it is my mistake, I'm looking to fit in 2in hole in the sink and Lock itself is 2in, so doesn't fit... Had to return.I'll maybe repeat my order if you will have smaller option, also for our requirements we need a smaller distances of the holes on top.Had no problems with return...Thanks for service.

They should send the tool to lock the drain with the drain

I purchased the Guardian Drain Lock for my outdoor drain that would get covered with leave or debris and clog. Thus causing a back up and flooding in the basement. Since my purchase of the Guardian Drain Lock I have had only one flood in my basement. The drain is working as I anticipated it would to solve the problem. To improve its performance for out doors use I recommend adding a screen on the inside of the dome, cause small debris will block the drain. I have to check the drain frequently to prevent flooding.
