Hercules Universal Sink Harness Kit

I learned about this amazing product from my granite countertops installers. Luckily I had one they installed to reference because the paper instructions are very difficult to understand. This product is great solution - no holes or supports from the counter is needed.

This harness mounting kit was exactly what I needed after my sink started to fall away from our granite because the installers had only used epoxy. I used this for a 50/50 stainless steel sink with center drains. Like another reviewer I used the instructions and online videos for guidance. Install went smoothly. My sink has some flex in the middle between the two bowls and my fisrt attempt didn't leave enough thread on the screw to tighten it snug to the granite. I moved the wire up one notch and was able to tighten it so that the sink was nice and snug all the way around. Just did the install yesterday and so far so good. I'll update this review after a few months and let you know if this thing holds up.1-Year Update- 6/18/2015It's been a year since I reinstalled the sink. I'm happy to report that there's been absolutely no movement/separation whatsoever. I have a garbage disposal attached and will often have a heavy dutch oven soaking full of water sitting in the sink. This product has definitely stood up to the test.

I moved to a house with a kitchen sink insufficiently jury-rigged to stay in place so that it sagged and the caulk was separated. A handyman said be could build a cradle for the sink for about $400. Hah! I ran across a YouTube video demonstrating a sink install using this harness and it looked like the perfect solution for my situation. The sink is stainless, so I wasn't concerned about the weight pulling the screws out of the sides of the cabinet where the sling must be attached. If I was installing a heavy undermount sink, I'd be concerned about the short screws and would likely install this using longer screws that extend past the cabinet walls into wood strips for reinforcement.The directions were very easy to follow and I believe DIY beginners wouldn't have any problems setting this up. A second pair of hands could come in handy but with the help of some 2x4s cut larger than your sink opening and some cleverly positioned straps, it's easy enough to do on your own.A gave this 4 stars because my particular install was pretty difficult, so that may not be fair. The previous homeowners put a sink meant for a 36" cabinet into a 33" cabinet. Doh. (Face palm.) That size of sink measures exactly 33". Folks, I do not recommend you try doing the same in your own home! Since I'd like to eventually replace the countertops, sink and base cabinet, I just went with what I already had. The protruding screw heads for the sling made the cabinet width ever so slightly narrower, but the sink was already snug so I had the wrestle it into place for longer than should have been necessary. I had the sink suspended just below the counter and applied caulk; this is where a second pair of hands would have been a huge help. It took quite a while to get the sink seated against the counter because of its size. I took turns cranking the screw for the underside of the sling and hammering the edges into position. By the time it was correctly placed and the sling was tightened, the silicone caulk had started to set up and there is no way to get a clean application with a finger swipe. A second person would have been able to do this for me while I worked underneath. I used a sharp utility knife to cut out extra caulk, but it looks junky to me.All that being said, I would recommend this sling if you are replacing or reinstalling a sink with a countertop that is already in place. It's unobtrusive and won't take up any cabinet storage space. It has a strong hold, but I'd be careful not to overtighten your main screw so that you don't risk pulling the screws out of the cabinet walls. The value for the money is very good as this does the job very well for the low price.

It took a full 2-3 hours for me to install, but it does work well. I installed it because my two-basin stainless sink fell down from the bottom of my granite counter top. Glue/silicone gave way after 12 years in the house and sink fell one day when it was loaded with water and dishes. Had to scrape clean top of sink and underside of countertop and install the four anchorpoints for the wires on this Hurcules harness kit. Took some planning to make the wires run beside, rather than directly across the two drains of the sink, however it all worked out and as I tightened the harness up, the new silocone squeezed out the sides, indicating a good all around seal. I would buy again and recommend this device. It takes more work to install than they indicate, but is a good kit and I would buy again.

I have used these multiple times and they work GREAT!

A year ago I Epoxy stud clamps for a kitchen stainless sink. I was meticulous with a clean surface and let the Epoxy dry for 48 hours before installing sink. After a few months of normal use the Epoxy studs fail. I looked up under the counter sink installation and saw a video using the Hercules sink strap installation kit and was impressed by the ease and simplicity of the kit. Recieved kit 24 hours later with prime. Installation time including prep (sink removal and old silicone cleaning took 2-3 hours. I am happy with this product and delivery was fast. Seems to be very sturdy after installation. I recommend this product and think it should last many many years. Although time will tell.
