Rated 4.9 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Great Product Easy Install This was very easy to install. After checking for studs behind the shower, drilled the holes in the shower wall and installed per the instructions. Very pleased. Only down side is they are high priced. July 17, 2013
Rated 5.0 out of 5.0 by Very easy install, held secure When your drilling an one and a quarter inch hole in your fiberglass surround, you want to feel secure. After the first hole and assembly with the waterproof seal on the unit I felt Great! Continue to install second unit and grab bar attached securely with out any problems. Enough so, I installed a second grab bar also. Found during installation that there was a 3/4" backer board glued to the rear of the surround, but these fasteners were deep enough to grab past the wood. Excellent, just need to come in a pair at a pair price. The only con is the anxiety of drilling the hole, locating the stud with your questionable stud finder.... February 10, 2015
Rated 5.0 out of 5.0 by First Time I Use This is a great product to install ADA recommended grab bars in baths. It has so much weight bearing capabilities, and the extremely important lateral force requirements. Manufacturer states 500-800 lbs. capacity. With the right tools it is an easy installation, I installed myself, and need the use of the grab bar. Remember though you need two. I ordered and thought they only came in pairs, but when I received the shipment there was only one. I did not read close enough to note that on the cat. August 4, 2015
Rated 5.0 out of 5.0 by Expensive but Extremely Good I needed to install some grab bars in my in-laws' fiberglass shower/tub surround. Not many options since it was not possible to install supports behind the surround and I wasn't going to trust standard hollow wall anchors. The Wingits fasteners were similar to standard hollow wall fasteners but on steroids! If you READ AND FOLLOW THE INSTRUCTIONS it would be difficult to go wrong. These things are solid and I have every confidence that they'll be around a lot longer than me. I'm a pretty big guy and I tried to pull the grab bars out of the wall - couldn't do it. I would definitely use again although it would be nice if the price got a bit more reasonable. May 20, 2014
Rated 5.0 out of 5.0 by Must have for grab bar installations The Wingit bolts are the perfect device to be able to install a grab bar where it is needed, and not have to worry about installing it into a stud, yet have it be safe and secure. Trying to find a stud often makes placement of the grab bar difficult and in awkward places. This product eliminates that worry. I highly recommend this product for any grab bar installations.

Rated 4.0 out of 5.0 by The Beast on the wall and in your wallet. Pro: Great product works perfectly as long as you use the grab bars from the same manufacture. Con: Pricy April 30, 2011
Rated 5.0 out of 5.0 by easy install great product!!!!!! wish I would have found them sooner. makes installs quick and easy!! one tip for easy install mount to grab bar then take off sticky backing paper then stick threw holes in wall then unmount grab bar. then loosen center screw push threw wall and then tighten. remount grab bar. this makes lining up screws much easier.

Rated 5.0 out of 5.0 by What a MONSTER I needed to install some grab bars for a friend of mine who recently had surgery and he is a pretty bike boy. We didn't want to tear into the walls to install blocking so we purchased a pair of these grab bar fasteners. Talk about BEAST - all stainless steel and you can tell it was built for a purpose. They were easy to install with their Apache drill bit through ceramic tile. My buddy has no worries about the grab bar coming loose or pulling out. I recommend using these with their grab bars since they are designed specifically for this fastener - easier and faster installation. Great product and highly recommend to everyone. October 2, 2011
