Key Features

26:1 Dispensing Force

The 26:1 drive mechanism gives you more leverage when working with thick epoxy. That means smoother trigger effort and better control when you are dispensing high-viscosity adhesive all day.

Steel Jobsite Build

A heavy-duty steel carriage is built for repetitive use instead of occasional homeowner duty. If this tool is going in and out of the truck and getting used hard, that matters.

Fits Multiple Cartridge Sizes

The Simpson Strong-Tie EDT22S Manual Dispensing Tool is made for 22 oz. side-by-side epoxy cartridges and includes conversion parts for 16.5 oz. 2:1-ratio cartridges, so you are not locked into one setup.

Overview

The Simpson Strong-Tie EDT22S Manual Dispensing Tool is a hand-operated epoxy adhesive dispenser built for 22 oz. cartridges. This is a manual dispensing tool designed for controlled epoxy adhesive application in anchoring and fastening work. Model Number: EDT22S. If you are setting anchors, installing threaded rod, or working with structural adhesive on a regular basis, this tool is built to make thick material easier to push and easier to control.

The big selling point here is the 26:1 drive mechanism. That ratio matters because epoxy adhesive is thick, especially the high-viscosity products used in anchoring applications. More mechanical advantage means less fight at the handle, more consistent bead flow, and less hand fatigue during repetitive dispensing. On real jobs, that translates to cleaner fills and more control when you need to keep adhesive where it belongs.

Simpson Strong-Tie built the EDT22S around a heavy-duty steel carriage for long-term use. This is not a flimsy caulk gun you burn through after a few cartridges. The steel construction is there for contractors and tradespeople who need a dispensing tool that can handle repeated use, ride in the truck, and keep working under steady jobsite demands. Lowe’s also calls out the all-steel construction for durability, which lines up with the product’s intended use.

Jobsite practicality is where this tool makes the most sense. The low-maintenance design is meant to reduce clogging and interruptions, and the controlled dispensing action helps maintain even adhesive flow. Amazon’s product description also notes that the handle sits under the cartridge for better balance and ease of use, and that the drive mechanism releases by pushing forward on the drive handle. Those are the small details that make repetitive anchor adhesive work less aggravating over the course of a day.

Compatibility is another strong point. The EDT22S is designed for 22 oz. side-by-side epoxy adhesive cartridges, and Simpson Strong-Tie includes the parts needed to convert it for use with a 16.5 oz. 2:1-ratio epoxy cartridge. That gives you flexibility across adhesive formats without needing a separate dispenser for every cartridge style in the shop.

This adhesive dispenser is best suited to pros and serious users who actually work with structural adhesive systems, not someone looking for a one-time-use tool. It fits concrete anchoring crews, general contractors, remodelers, and anyone doing regular adhesive anchoring work with Simpson Strong-Tie epoxy systems. If your goal is clean, repeatable epoxy dispensing with less effort than a basic gun, this is the right kind of tool.

Make Thick Epoxy Easier to Dispense

When you are working with structural adhesive, trigger effort matters. The EDT22S is set up to give you more push with less strain so you can keep the flow steady instead of fighting the tool.
