Black & Decker WORKMATE 400 workbench Parts

To open a Black & Decker WORKMATE workbench, we set it upright, release the locking clips, then pull the legs and top apart until the frame fully spreads and the locks snap into place. This ensures the bench is stable before you clamp or cut.

Steps to open and lock it safely

• Stand the WORKMATE on its end so the legs can swing freely.
• Find the locking clips or latches near the folding joints.
• Pull the clips outward to release the folded position.
• Spread the legs and top apart until the bench opens flat.
• Press down on the top (using body weight if needed) so the locks fully seat.
• Confirm both sides are equally opened and not twisted.

Quick stability check (before you use it)

A WORKMATE is safest when it is fully opened and both locking points are engaged.

Check	What you want to see	What to do if it fails
Locks engaged	Clips/latches are fully seated	Re-open, then press down until they snap in
No wobble	Bench does not rock on the floor	Move to a flatter surface, re-check leg spread
Top alignment	Jaws/top halves sit level	Re-open and make sure both sides open evenly
Clamp action	Handles turn smoothly and clamp evenly	Back off, re-align the jaws, then tighten again

If it feels stuck or won’t snap open

• Check for sawdust, paint, or rust at the hinge points; clean and re-try.
• Look for a bent leg brace or twisted frame; straighten before forcing it.
• Loosen the clamping handles slightly; some units bind if the jaws are tightened.
• Apply a small amount of light oil to pivots, then wipe off excess.

Why it matters

If the WORKMATE is not fully opened and locked, it can fold unexpectedly under load. A proper lock-in also keeps the clamping jaws square, which helps when cutting, sanding, or holding a workpiece.

Yes. Black & Decker WORKMATE benches like the WORKMATE are good for light to medium DIY tasks because they combine a portable workbench with a built-in vise-style clamping surface, so you can hold wood, trim, and small assemblies securely while you cut, drill, sand, or glue.

What “good” means for a WORKMATE-STYLE workbench

A WORKMATE is a strong choice when you need a compact, foldable bench that sets up fast and stores easily.

• Works as a small workbench, clamping station, and sawhorse-style support
• Dual clamping handles help you grip uneven or awkward pieces
• Swivel pegs (bench dogs) add flexibility for different shapes
• Folding frame makes it easy to carry and store
• Great for garages, apartments, and jobsite punch-list work

Where it shines (and where it does not)

These benches are designed for versatility, not heavy industrial loads.

Use case	Fit for a WORKMATE	Notes
Holding boards for drilling/sanding	Excellent	Clamping is the main advantage
Small glue-ups and assembly	Very good	Add scrap wood pads to protect surfaces
Cutting long lumber	Good	Support the free end with a stand or sawhorse
Heavy hand-planing or large doors	Limited	A heavier, wider bench is more stable

Quick setup and safety tips

• Set the bench on a flat surface and fully lock it open before loading it.
• Keep fingers clear of the moving jaws when tightening the cranks.
• Use scrap wood as jaw pads to prevent marring softwood or finished pieces.
• For long stock, add outfeed support so the workpiece does not tip the bench.
• Re-tighten hardware periodically; folding benches loosen over time with vibration.

Why it matters

A portable clamping workbench improves accuracy and safety because the work stays put. That means cleaner cuts, straighter holes, and less chance of the material spinning or shifting while you use a drill, jigsaw, or sander.

Finding parts and model details

For the best parts match, confirm the exact model marking on your bench and then search by model number on Sears PartsDirect. You can also use our guide, how to find your appliance model number (and what it means for parts), to identify the correct model information.

The Black & Decker WORKMATE line is more than 50 years old. The original WORKMATE design dates to the late 1960s, and WORKMATE models were widely sold in the U.S. starting in the 1970s. For your Black & Decker WORKMATE workbench, the exact age depends on the specific type/version and when it was purchased.

How to estimate the age of your WORKMATE workbench

We use a few quick checks to narrow down the production era without guessing.

• Look for a type number or date code on the frame, underside of the top, or a label near the hinge area.
• Check for country of manufacture markings (often helps separate early vs. later runs).
• Note the jaw/top style (wood vs. composite, handle style, and vise mechanism design).
• Compare hardware (leg braces, pivot points, and fastener style) for older vs. newer revisions.
• If you still have the original receipt or packaging, use that purchase date as the most accurate reference.

Common WORKMATE timeline (quick reference)

These milestones help you place your bench in the right decade.

Era	What it usually means	What you can do next
Late 1960s	Original concept and earliest versions	Look for early markings and older hardware styles
1970s	Broad U.S. availability and popular adoption	Check for U.S. market labels and type numbers
1980s to 2000s	Multiple revisions and variants	Match your jaw/handle style to your type/version
2010s to today	Modern production runs and updated materials	Use label codes and purchase history

Why it matters

Knowing the approximate age helps us match the right replacement hardware and accessories (clamping jaws, crank/handle components, leg braces, and fasteners) and avoids ordering parts that fit a different WORKMATE type.

Finding parts for your WORKMATE

We recommend searching by the most specific identifier you have (type/version, label code, or the exact model marking). If you do not see the exact breakdown you need, search by your identifiers on Sears PartsDirect. You can also use our guide: how to find your appliance model number (and what it means for parts).

A Black & Decker WORKMATE workbench is a portable clamping and support station: we use it as a small workbench, a bench vise for holding material, and a stand for benchtop tools. It’s ideal for cutting, drilling, sanding, and assembly when you need a stable, hands-free setup.

Common ways we use a WORKMATE workbench

• Clamp wood, metal, or plastic between the jaws for sawing, filing, or sanding
• Use the top as a compact work surface for measuring, marking, and assembly
• Hold irregular shapes (trim, dowels, small frames) more securely than by hand
• Support long boards as an outfeed or temporary support during cutting
• Mount or steady certain benchtop tools (when the tool base fits and can be secured)

What it can hold and how (typical setup)

Most WORKMATE-STYLE benches clamp in two main ways: between the front and rear jaws, or on the tabletop using bench dogs (pegs) and the jaw faces.

Task	Best holding method	Why it helps
Hand sawing a board	Clamp between jaws	Keeps the cut line steady and safer
Sanding a small part	Clamp between jaws	Prevents chatter and rounded edges
Drilling a piece	Clamp between jaws	Reduces spinning and bit grab
Light assembly/gluing	Tabletop support	Frees both hands for alignment

Quick safety and setup checks

• Lock the legs fully open before loading weight
• Keep the load centered; avoid side-loading that can tip the bench
• Clamp the work tight enough that it cannot shift, but not so tight that you crush soft wood
• Keep hands clear of the jaws and moving tools; clamp first, then cut or drill
• If the jaws slip, inspect for worn jaw faces, loose hardware, or damaged threads

Why it matters

Using a WORKMATE as a clamp-and-support station improves accuracy and reduces the chance of the workpiece moving unexpectedly, especially during cutting and drilling.

If you need replacement hardware or want to search by the exact WORKMATE version you own, we recommend using the model and parts lookup on Sears PartsDirect.
