Don-Jo FDT-1 Frame Dimpler Tool for Hollow Metal Door Frame Installation

The Don-Jo FDT-1 Frame Dimpler Tool is a purpose-built installation aid designed for use when fitting a new hollow metal frame into an existing masonry or stud opening.

The double-sided design extends the tool's service life, allowing installers to flip to the opposite side after extensive use on one side. Included with the tool are two Allen screws and a long-arm Allen wrench for immediate, out-of-the-box use.

Don-Jo FDT1 – Frequently Asked Questions

1) What is the Don-Jo FDT-1 frame dimpler tool actually used for on a hollow metal frame install?
The FDT-1 puts a dimple into a hollow metal door frame so the fastener head seats flush instead of standing proud. It is meant for fitting a new hollow metal frame into an existing masonry or stud opening, which is the case where you are anchoring through the frame face and need a clean seat for the screw. It is an installation tool, not a piece of door hardware that stays on the opening.
2) Does the Don-Jo FDT-1 come with everything needed, or do I have to buy a wrench separately?
Two Allen screws and a long-arm Allen wrench ship with the FDT-1, so it works out of the box. No separate driver purchase. The tool works by turning the Allen screw with the wrench to press the dimple into the frame, so the wrench is part of the mechanism, not just a setup accessory.
3) Is the FDT-1 dimpler good for repeated commercial use or is it a one-job tool?
Hardened steel, and double-sided. When one side wears from extended use, you flip it and keep working, which is why Don-Jo built it for crews doing frames day in and day out rather than a single opening. It is a commercial-duty tool.
4) Do I need a frame dimpler, or can I just countersink the hollow metal frame with a drill?
A dimpler is the tool for this when you want the fastener to finish flush and clean on a hollow metal frame face. The FDT-1 presses the dimple in with an Allen screw driven by the wrench rather than removing metal, so you get a consistent seat for the fastener across every anchor point on the frame. If you are installing a new hollow metal frame into an existing masonry or stud opening and face-fastening it, that is exactly the job this tool was made for.
5) Will the Don-Jo FDT-1 work on a wood door frame or an aluminum frame?
No. The FDT-1 is built for hollow metal frames. Dimpling relies on the frame being formed sheet steel that will take a pressed impression from the tool without splitting or cracking, so wood jambs and aluminum storefront frames are outside what it is for. On those, you fasten by the method the frame manufacturer specifies instead.
6) How do I order the Don-Jo frame dimpler, and are there different models or sizes?
There is one model, FDT-1, and no size or finish choices to specify. Ask for the Don-Jo FDT-1 frame dimpler tool and you get the tool with the two Allen screws and the long-arm wrench.
