The Aquia IV One-Piece Elongated Dual Flush 1.28 and 0.8 GPF Universal Height WASHLET + Ready Toilet with CEFIONTECT is the epitome of modern form and function. The skirted design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. The Aquia IV features TOTO’s DYNAMAX TORNADO FLUSH, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT technology, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with DYNAMAX TORNADO FLUSH, helps to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The chrome center-mounted push button that sits atop of the tank allows you to proactively conserve water by choosing between a 0.8 GPF rinse or 1.28 GPF for tougher jobs. This version of the Aquia IV offers TOTO T40 WASHLET+ compatibility for when you are ready to upgrade. WASHLET+ toilets feature a channel on the bowl surface to help conceal your WASHLET+ supply line and power cord for seamless integration. The Universal Height design allows for a more comfortable seat position across a wide range of users. The TOTO Aquia IV meets the standards for EPA WaterSense , and California’s CEC and CALGreen requirements. The Aquia IV comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. Includes a SoftClose toilet seat (#SS124). Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines.

Great item
Size: 9 Holes
Works great Would be nice to have another peg to make sure it stays in line. Just used a drill bit of the same size.
Worth the investment

Game-Changer for Clean, Accurate Shelf Pin Holes!
This shelf pin jig absolutely delivered on everything I needed — the ease of use was fantastic right out of the box. Once I got the layout aligned, drilling was quick and precise. The accuracy is impressive, with clean, straight holes every time, and the included bits worked like a charm. The design is clever, compact, and durable — the aluminum plate feels premium and makes it easy to keep things straight. I love the versatility too; switching between 5mm and 1/4" bits was fast, and the guide holes are clearly labeled. The size is ideal for cabinets, bookcases, and even tighter spaces where a bulky jig wouldn’t fit. For anyone needing quick, repeatable shelf pin drilling, this jig speeds up the use and keeps your project moving fast without compromising quality. If you're doing any custom shelving or cabinet work, this is a must-have tool that saves time and eliminates guesswork.

Works well for DIY
Worked well for building bookshelf. Wish it maybe had som little pads on the back as some times it would slide a bit, but if I tightened it more it would dent the wood slightly. Overall very easy to use and worked well for its intended use.

Good addition to my jig collection!!!
Size: 9 Holes
It works great! Would be better if it had a Brad style drill bit instead of the ones that came with it.
