RJS Tech

RJS Tech is a manufacturer of plumbing specialty hardware built around solving one of the most common headaches in toilet installation and removal: stuck, stripped, or spinning closet bolts. The company's catalog centers on two flagship lines, SetFast closet bolts and the Jam-Bar toilet bolt lock wrench, both designed specifically for the realities of field plumbing work.

Rather than offering a broad catalog of general plumbing hardware, RJS Tech has built its reputation around specialty tools that address a narrow but persistent pain point trade plumbers encounter on nearly every toilet job.

Product Lines

SetFast closet bolts feature a self-adjusting design made from solid brass with stainless steel washers, eliminating the need to hacksaw excess bolt length or mark up porcelain during installation. The bolts are available in multiple lengths, including an extended XT version suited for flanges recessed relative to the finished floor.

The Jam-Bar toilet bolt lock wrench addresses the opposite end of the job: removing old, corroded, or spinning closet bolts. Its flat blade inserts alongside the nut while a patented tooth design grips and locks the bolt in place, letting a plumber back off the nut without the bolt spinning freely.

Why Contractors Specify RJS Tech

Plumbers who have fought a rusted, spinning closet bolt while trying to swap a toilet understand why RJS Tech's tools have found a following in the trade. Traditional closet bolts often require field-cutting to length, a step that eats time and risks nicking porcelain.

SetFast bolts remove that step entirely, while the Jam-Bar wrench turns a frustrating, multi-tool removal job into a quick single-tool fix. For plumbers billing by the job, tools that shave minutes off routine toilet installs and removals add up over a busy week.

How to Choose RJS Tech Products

Selecting the right SetFast bolt length starts with measuring flange depth relative to the finished floor. Standard lengths cover typical installations, while the XT length is built for flanges set lower than a standard installation.

For toilet removal jobs where bolts show visible corrosion or have already sheared partway, the Jam-Bar wrench is worth keeping in a service truck alongside a hacksaw as a backup. Plumbers stocking service trucks often keep both SetFast bolts and a Jam-Bar wrench on hand, since one addresses new installations and the other addresses removal of existing, aged hardware.

Frequently Asked Questions

What makes SetFast closet bolts different from standard closet bolts?

SetFast bolts use a self-adjusting design made from solid brass with stainless steel washers, so installers do not need to cut the bolt to length or risk marking the porcelain during a toilet installation.

When should a plumber use the XT length SetFast bolt instead of the standard length?

The XT length is designed for flanges recessed relative to the finished floor, a common scenario with tile or added flooring layers that raise the floor height after the flange was originally set.

How does the Jam-Bar wrench remove a spinning closet bolt?

The Jam-Bar's flat blade inserts alongside the nut and its patented tooth design grips and locks the bolt in place, allowing the nut to be backed off without the bolt spinning inside the flange.

Are RJS Tech products limited to residential toilet installations?

RJS Tech's closet bolts and Jam-Bar wrench are built for standard toilet flange configurations found in both residential and light commercial plumbing work.

What should be kept on a service truck for handling stubborn closet bolts?

A Jam-Bar wrench addresses bolts that spin or resist removal, while a hacksaw remains a useful backup for bolts that have corroded beyond what a wrench can grip.
