Toggle Clamps NZ: Horizontal, Vertical & Latch Buying Guide
A toggle clamp is a quick-acting, lever-operated clamp that locks a workpiece in place with one flick of the handle, which is why it is the standard hold-down on welding jigs, drilling fixtures and assembly benches. Choose the type by how the clamp needs to move (horizontal, vertical, push-pull or latch), then size it by holding capacity, reach and base style. This guide covers the toggle clamps we list in NZ and how to match one to the job.
How a toggle clamp works
Every toggle clamp uses a linkage that goes "over centre". As you push the handle home, the pivots pass a straight line and the clamp locks: load pushing back on the clamp drives it further into the locked position rather than springing it open. That is what lets a small hand clamp hold a part steady through welding heat, drilling or repeated assembly, and release it again in a second.
Most toggle clamps are bolted or welded to a bench, fixture plate or jig base, so they are a set-and-repeat tool rather than a general-purpose clamp you move around the workshop.
Types of toggle clamp
Horizontal toggle clamps
On a horizontal toggle clamp the handle lies flat when the clamp is locked. That gives a low profile, which keeps the handle out of the way of a welding torch, router or drill and lets you clamp under overhangs. Horizontal clamps are the usual choice for holding flat stock, sheet and frames down on a jig. The bar swings up and back to open, so check the opening angle gives you enough clearance to load the part.
Vertical toggle clamps
On a vertical toggle clamp the handle stands upright when the clamp is locked and the bar comes down onto the work. The handle is easy to grab from above, and the clamp opens wide for loading. Vertical clamps suit fixtures where you reach in from the top and where the space beside the clamp is tight.
Latch toggle clamps
A latch clamp (sometimes called a pull-action or hook clamp) pulls a U-bolt toward its base instead of pressing down. Hook the U-bolt over a catch, push the handle home and the two parts are drawn together and locked. They are used to hold lids, covers, doors and panels shut, to pull two jig halves together, and to tension parts during assembly. Latch clamps carry the highest holding capacities in our range.
Push-pull toggle clamps
A push-pull (plunger) clamp drives a straight plunger in and out along its own axis, which suits pushing a part against a stop or holding it from the side. We don't currently list push-pull clamps, so if your fixture needs one, a horizontal or vertical clamp mounted on its side is sometimes a workable alternative, depending on the layout.
What to look for
Holding capacity
Holding capacity is the load the clamp is rated to resist once it is locked. It is not a measure of how hard the spindle presses on the work, which depends on how you set the spindle. Pick a clamp rated comfortably above the force the part will see in use (vibration, cutting forces, weld distortion pulling against it) and use more than one clamp on long parts rather than relying on a single large one.
Our toggle clamps are rated from 90 kg (light horizontal and vertical clamps) up to 900 kg (heavy latch clamps).
Flanged vs straight base
A flanged base has a mounting flange with bolt holes that sits flat on top of the bench or fixture plate, so you can bolt it straight down. This is the most common style and the easiest to mount, move and re-position. A straight base has no flange; it is typically fixed through the base body itself, which suits mounting against the side of a rail, block or upright, or tight spots where a flange would get in the way. Choose the base that matches the surface you're mounting to.
Spindle adjustment
The contact point on most horizontal and vertical toggle clamps is a threaded spindle held in the bar by lock nuts. Wind it up or down to set where it touches the work, then lock the nuts. Getting this right is what makes the clamp work: set it so the clamp locks over centre with firm pressure, without having to force the handle. A cushion spindle has a rubber tip that grips and helps protect finished or painted surfaces. A U bar has a slot that lets you slide the spindle along the bar to change the reach; a solid bar takes the spindle in a fixed position.
Reach and opening angles
Reach is how far from the clamp the spindle lands, so it decides where you can mount the clamp relative to the part. Bar and handle opening angles tell you how far the clamp swings clear for loading and unloading. Where we list them, these figures are in the table below.

How to choose by job
- Welding jigs and frame fixtures: horizontal clamps keep the handle low and clear of the torch. The 250 kg horizontal clamp suits heavier sections; the 90 kg clamps suit light sheet and tube work.
- Drilling, routing and woodworking jigs: a cushion spindle grips without marking the work. Use a vertical clamp where you load from above, a horizontal one where the handle needs to stay out of the cutter's path.
- Reaching over a part or fence: the 180 kg vertical clamp has the longest listed reach in our range (204 mm), and its U bar lets you move the spindle along the bar.
- Mounting to the side of a rail or block: the straight-base horizontal clamp.
- Holding lids, doors and panels shut, or pulling parts together: latch clamps. Size by holding capacity and by U-bolt length, which sets how far apart the clamp and catch can sit. The two 900 kg latch clamps differ in U-bolt length and width, so check which fits your catch.
Setting up and looking after toggle clamps
- Bolt clamps down firmly on a flat surface. A clamp that can rock on its base won't hold consistently.
- Set the spindle with the part in place, so the handle locks over centre with a firm push. If you have to hammer the handle home, back the spindle off.
- Tighten the spindle lock nuts after adjusting, and re-check them on jigs that see vibration.
- Keep weld spatter off the pivots and spindle thread, and put a drop of light oil on the pivots now and then.
- Replace worn cushion tips before the spindle starts marking the work.
FAQ
Where can I buy toggle clamps in NZ?
We list horizontal, vertical and latch toggle clamps online in our toggle clamps collection, with holding capacities from 90 kg to 900 kg. Stock changes, so check the product page for current availability.
What is the difference between a horizontal and a vertical toggle clamp?
It is the position of the handle when the clamp is locked. A horizontal toggle clamp's handle lies flat for a low profile; a vertical toggle clamp's handle stands upright and is easy to reach from above.
What does holding capacity mean on a toggle clamp?
It is the load the clamp is rated to resist when locked. The pressure on the work depends on how you set the spindle.
What is a latch toggle clamp used for?
Pulling two parts together and holding them there: lids, hatches, doors, panels, mould halves and jig sections. The U-bolt hooks over a catch and the handle locks it tight.
