Holding two pieces at a true 90° angle can be frustrating when ordinary clamps shift, twist, or block access to the joint. The DASBET 2Pack Cast Iron Welders Angle Clamp gives you a heavier two-axis fixture designed to hold metal or wood while you align, tack, weld, screw, or assemble a corner. Its 2.1-inch maximum jaw opening and swiveling clamping mechanism make it especially useful when the two workpieces are not exactly the same thickness. The tradeoff is simple: at about 8 lb per clamp, this is a substantial shop tool rather than a lightweight corner clamp you will want to carry around all day.
Quick Verdict
Rating: 8.4/10, Recommended with caveats
Best For: Welders, fabricators, woodworkers, and DIY users who frequently assemble 90° joints in square tubing, angle iron, plate, cabinets, boxes, or frames.
Bottom Line: The DASBET clamp set combines a heavy cast iron and steel build with swiveling jaws that can hold workpieces of different thicknesses. Its main limitation is the 2.1-inch jaw opening, so you should check your stock size before buying.

What Is the DASBET 2Pack Angle Clamp?
The DASBET ZTC-0513-01 is a two-pack of heavy two-axis clamps built for holding workpieces at a 90° angle. The body uses cast iron and steel, while the clamping mechanism combines a sliding T-shaped handle with rotating jaws and a swivel-mounted spindle.
The key advantage is its ability to adapt when the pieces on each side of a joint differ in thickness. Instead of requiring two identical boards or metal sections, the swiveling mechanism can adjust its contact with each workpiece while the fixture maintains the right-angle relationship.
This makes the set relevant to welding and fabrication work, but it is not limited to metal. The listed applications also include woodworking tasks such as assembling cabinets, boxes, and frames.
Who Should Buy It?
Best For
- Fabricators who regularly tack or weld square tubing and angle iron at 90°.
- Woodworkers assembling boxes, cabinets, frames, and similar right-angle projects.
- DIY users who want two substantial corner fixtures rather than small lightweight clamps.
Skip If
- Your material requires more than the 2.1-inch maximum jaw opening.
- You mainly need a small, lightweight clamp for occasional craft projects.
- You need a fixture with a documented load rating or verified manufacturer warranty terms.
Before You Buy: Measure the thickness and shape of the material you intend to clamp. The verified maximum jaw opening is 2.1 inches / 54 mm, so oversized tubing, thick assemblies, or unusually shaped workpieces may not fit.
Build Quality and Materials
The clamp body is made from cast iron and steel, which explains much of its roughly 8-pound-per-clamp weight. That mass can be useful on a workbench because a heavier fixture is less prone to being nudged around while you are positioning stock.
The manufacturer listing describes a sprayed plastic surface treatment intended to help protect the metal against rust and corrosion. That does not make the clamp maintenance-free or suitable for being left exposed to rain. You should still keep the tool dry and clean, especially after fabrication work that leaves grinding dust, metal particles, or welding residue around the screw and sliding surfaces.
Clamping Capacity and Jaw Design
The maximum jaw opening is 2.1 inches / 54 mm. Jaw height is 1.36 inches / 34.5 mm, while the jaw width is 4 inches and the listed tip-to-tip width is 5-9/16 inches. These dimensions make the fixture more substantial than compact woodworking corner clamps, but they also establish a clear size limit.
The rotating jaw is one of the more useful parts of the design. A two-way swivel-mounted spindle allows the clamping block to adjust to workpieces of different thicknesses. For example, you may be able to secure two sections that do not have identical dimensions without forcing the movable jaw to sit flat against only one side.
Pro Tip: Before tightening fully, seat both pieces against the 90° faces and check the joint with a square. The clamp holds the setup, but verifying alignment before welding or fastening helps prevent a small positioning error from becoming permanent.
Stability and Ease of Adjustment
DASBET uses a sliding T-shaped single handle rather than a small fixed knob. This gives you room to reposition the handle as you tighten the spindle. The flat sliding block and substantial body are designed to reduce movement once the workpiece is secured.
The benefit is most noticeable during setup. You can position the workpieces, let the swiveling jaw adapt to their thickness, and then tighten the screw instead of juggling several independent clamps. The weight also helps the fixture feel planted on a bench.
The downside is portability. A pair of clamps at about 8 lb each represents a considerable amount of tool weight. If your priority is a compact clamp that stays in a portable toolbox, a lighter corner clamp may be more convenient.
How It Performs in Real Use
Square Tubing and Frame Fabrication
Square tubing is a natural match for this design because the clamp can hold two sections in a fixed 90° relationship while you check alignment and place tack welds. The open areas around the joint can also make it easier to reach the work than trying to hold the corner with several general-purpose clamps.
Angle Iron, Plate, and Channel
The listed applications include angle iron, plate, pipe, and channel iron. The swiveling clamping block is useful when the geometry on each side of the fixture is not identical. You should still confirm that the contact surfaces are secure before applying heat or force.
Cabinets, Boxes, and Frames
The clamp can also be used for woodworking when a sturdy right-angle fixture is useful during screwing, nailing, or assembly. Because the tool is considerably heavier than many woodworking corner clamps, protect finished or delicate surfaces and avoid excessive tightening.
Mixed-Thickness Workpieces
This is one of the more distinctive use cases. The bidirectional rotating jaw is designed to accommodate pieces with different thicknesses, which can save time when the two sides of your 90° joint are not identical. The feature does not remove the need to check squareness, but it makes initial positioning less awkward.
Setup Tips for Better Results
- Measure first: Confirm that both workpieces fit within the 2.1-inch maximum jaw opening.
- Clean the contact areas: Remove loose debris that could keep the stock from sitting flat against the fixture.
- Position before tightening: Seat both pieces against the right-angle faces before applying full clamping pressure.
- Check with a square: Verify alignment before welding, drilling, nailing, or screwing the joint permanently.
- Tighten only as much as needed: Excessive pressure is unnecessary and can damage softer workpieces.
- For welding, plan access first: Make sure the clamp is positioned where it will not interfere with the tack or weld location you need to reach.
Maintenance and Shop Safety
Keep the threaded spindle and moving contact areas free of grinding dust, weld spatter, sawdust, and other debris. A clean screw mechanism is easier to adjust and less likely to bind. Wipe the clamp after use and store it in a dry location rather than relying only on the surface coating for corrosion protection.
When welding, remember that a holding fixture does not replace normal welding safety practices. Use suitable personal protective equipment, maintain a safe work area, and allow hot metal and nearby tooling to cool before handling them. Follow the instructions for your welding equipment and the clamp itself.

Is It Worth the Price?
The DASBET set sits in the value-oriented part of the two-axis fixture market if your main goal is getting two heavy clamps for repeated 90° assembly work. Its cast iron construction, swiveling jaw design, and two-clamp package offer more shop utility than a simple lightweight corner clamp.
The value is strongest for someone who regularly makes frames, boxes, square-tube assemblies, or similar right-angle joints. If you only need to hold an occasional small woodworking corner, the extra weight and capacity may be unnecessary. Likewise, buyers who need larger clamping capacity or professional fixture-system features may be better served by a more specialized vise.
How It Compares to Alternatives
The Strong Hand Tools WAC35D is a more specialized professional 2-axis fixture vise with features aimed at fabrication work, including a quick-acting adjustment system. It is worth comparing if fast repetitive setup and dedicated shop-fixture features matter more to you than buying a simpler two-clamp package.
The Bessey WS series takes a lighter angle-clamping approach that is particularly familiar in woodworking and assembly work. The DASBET makes more sense when you want the mass of a cast iron welding-style fixture and plan to work with both metal and wood rather than primarily lighter cabinet or frame assembly.
