The TOTO DuoFit In-Wall Tank Dual-Flush System with Copper Supply takes up less floor space, giving your bathroom a more open feel and making it easier to clean. This modern design uses TOTO's Dual-Max® flushing system, allowing you to proactively conserve water with a full or light flush option. Choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The DUOFIT® harness allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals. The in-wall unit can support up to 880lbs when installed properly. The kit arrives ready to be installed within a 2” x 6” stud setting with a 2" x 6" polyethylene waste outlet. If you require installation within a 2” x 4” setting, you will need to additionally purchase TOTO’s 2” x 4” PVC outlet kit (THU343). To enhance the installation with a WASHLET® bidet seat, there is a pre-attached copper supply built into the system. The separately sold TOTO WASHLET® Connection kit will complete your WASHLET® install (THU805). This DUOFIT® requires the toilet bowl and push plate to be purchased separately.

Good, inexpensive work watch
Color: all black watch
Bought as a working watch so I don’t wreck my good watches. It’s been working just fine and holding up well while not taking very good care of it. Keeps accurate time. Glass has stayed clear. Black finish looks good and is holding up well. Seems to hold up with steady pounding.
Stop watch buttons are a bit crude and will mess up your time when your hand gets pushed back against it during hard labor. However, I have not babied this watch at all.

It’s not an ugly watch, but I did not think the watch looked as nice in person This watch lost several minutes over a few months. It is light and feels cheap. However, it was not expensive, it’s comfortable to wear and beauty is in the eye of the beholder.
