## Overview

The PermaFLOW PF0990 TANKBRACE is a lightweight, plastic toilet tank support designed for 1" to 2" gaps. It installs easily without tools, preventing tank movement that can cause cracks and leaks. Ideal for professionals seeking a quick, reliable upgrade to bathroom stability.

## Description

Tankbrace toilet tank support is a Plumbing accessory that fixes toilet tank gaps and prevents them from cracking and leaking. It needs no tools and is easy to install.

Review: MINIMUM 1" gap, if it's smaller - this isn't the product you need. The adjustment knob is required for the system to work, and it's 1" to start - so the rest of the size adjustment bits are useless to you without the 1" knob to attach them. You cannot just adjust a tiny amount, the adjustment knob will be too large. Just go get regular shims in that case. If this is more than 2", it's also not the right tool - the mechanism you stack parts with is flimsy and questionable - choose one of the other systems for toilet support. I don't know why this was almost 20$, it's about 4cents worth of 3d printed material.
Review: I replaced the bolts in my toilet tank that connect it to the bowl. I noticed some movement, not much, in the tank, but from everything I read, that was normal for the type of installation bolts that I used. That said, I was still a little nervous that someone would lean back and crack the tank or something, so I got this kit to brace the tank against the wall, and it was very easy to install these to the tank and brace the tank against the wall. Made me feel alot better for someone to come poop at my house.
