Describe the holding capacity, plunger travel, or fixture task you need. ChatMRO finds the exact match, shows alternatives, and gives you a quote — in seconds. No part number needed.
A straight line action workpiece clamp (also called a push/pull toggle clamp) uses a toggle-linkage handle to drive a plunger in and out along a straight axis, pressing directly against the side or end of a workpiece to hold it in place. Unlike hold-down toggle clamps that pivot a clamping arm downward, straight line clamps move linearly — many can be locked in either of two positions, letting the same clamp function as either a push clamp or a pull clamp.
Tool and die makers, fixture designers, and assembly line engineers rely on straight line action clamps wherever a workpiece needs to be squeezed between two surfaces, wedged against a fixed rail, or held together during welding, bonding, or machining — common in jigs, weld fixtures, injection mold halves, and movable assembly bases. Their quick-acting toggle-lock mechanism, ability to stay mechanically locked even under vibration, and reversible push/pull configuration make them a standard workholding component across manufacturing and woodworking fixture design.
Common holding capacities: 100 lb to 2,500+ lb depending on model size, with flanged or unflanged mounting bases, plunger travel typically 1" to 3"+, and plunger threads commonly in the 5/16-18 to 1/2-13 range for larger models. Manual (handle-operated) and pneumatic (air-cylinder-driven) versions are both widely available.

Keeping stock tight against fences, light assembly jigs, and hobby/woodworking applications. 100–300 lb capacity clamps dominate here.
Welding fixtures, assembly tooling, and general workholding across manufacturing. 650–2,500 lb capacity clamps dominate here.
Repetitive clamping cycles integrated with automated equipment or requiring remote actuation.
Straight line action workpiece clamps are supplied by workholding specialists such as Jergens and De-Sta-Co, spanning light-duty woodworking versions to heavy-duty flanged industrial models. Here's how to navigate the class without a 40-tab browser session.

The jig and woodworking workhorse. 100–300 lb holding capacity, push/pull toggle action, locks in two positions for use as either a push or pull clamp. Compact size for movable bases and small fixtures.
Search 100–300 lb Capacity Series →Flanged base for secure bolt-down mounting, hardened steel pivot pins and bushings, black oxide finish. Reverse action option keeps the handle out of the work zone. Available with additional locking mechanism on higher-capacity models.
Search 650–2,500 lb Capacity Series →Self-contained pneumatic cylinder actuation with the same toggle-lock safety as manual clamps — remains mechanically locked even during total air pressure loss. Optional magnetic piston ring for position sensing.

| Class | Holding Capacity | Base Type | Best For | Actuation | Plunger Travel | ChatMRO Verdict |
|---|---|---|---|---|---|---|
| Light-Duty (100–300 lb) | 100–300 lb | Flanged or unflanged | Woodworking jigs, light assembly | Manual handle | ~1" typical | Best entry point for light clamping loads and hobby/shop use |
| Standard Flanged (650–700 lb) | 650–700 lb | Flanged | General manufacturing jigs and fixtures | Manual handle | ~1–2" | Good middle ground for most fixture-building applications |
| Heavy-Duty Flanged (1,326–2,500 lb) | 1,326–2,500 lb | Flanged | Welding fixtures, heavy workholding | Manual handle | ~2–3"+ | Go-to when clamping force demands exceed standard-duty models |
| High-Capacity (2,500+ lb, De-Sta-Co style) | 2,500+ lb | Flanged | Injection mold halves, heavy-duty tooling | Manual handle | ~1"+ | Use when very high holding capacity in a compact footprint is needed |
| Pneumatic Power Clamp | Cylinder/pressure dependent | Flanged, self-contained | Automated production lines | Pneumatic cylinder | Model-specific | Best for repetitive cycling integrated with automated equipment |
| Generic Import Toggle Clamp | Variable | Variable | Budget, occasional light use | Manual handle | Variable | Verify holding capacity rating and pivot pin hardness before daily production use |

Whether you're a fixture designer building a new weld jig, or a shop technician replacing a worn-out toggle clamp — use this framework before you procure.
Holding capacity refers to the maximum external force the locked clamp can resist without permanent deformation — size with margin above your expected clamping load, not just the nominal force needed to hold the part in place.
Some straight line clamps lock in two positions, letting the same clamp function as either a push or pull clamp — confirm whether your fixture needs one, the other, or both from the same unit.
Confirm the plunger's total travel distance and thread size (for mounting clamp tips or extensions) fit your specific workpiece dimensions and fixture layout.
Flanged bases offer secure bolt-down mounting for permanent fixture installations; unflanged or alternative mounting styles may suit specific space-constrained designs.
Manual handle-operated clamps suit occasional or operator-controlled clamping; pneumatic versions suit automated or high-cycle-rate production lines, while retaining toggle-lock safety even during air pressure loss.
Two clamps with similar holding capacity can have very different plunger travel and mounting dimensions. Search by function on ChatMRO — the AI surfaces exact matches AND available substitutes that fit your fixture geometry.
Manual clamps are designed for operator actuation; high-cycle-rate automated lines benefit from pneumatic power clamps designed for repetitive cycling without operator fatigue.
Standard-action clamps position the handle where it can interfere with tooling access. Reverse-action models keep the handle out of the work zone — confirm which orientation your fixture design requires.

Straight line action workpiece clamps are among the most widely specified workholding components in jig and fixture design across manufacturing, woodworking, and tooling applications. Manufacturers such as Jergens and De-Sta-Co command significant market presence due to their proven push/pull toggle mechanisms, broad holding capacity range from 100 lb to over 2,500 lb, and flanged mounting options suited to permanent fixture installation. Procurement professionals and fixture designers in India, Southeast Asia, and North America regularly source straight line action clamps for welding fixtures, assembly jigs, injection mold tooling, and general workholding applications.
ChatMRO simplifies this procurement process by providing AI-powered natural language search across a catalogue of 30 million+ indexed industrial parts. Engineers and buyers no longer need to memorize model codes or navigate multi-level filter trees to find the right clamp. A simple description of the holding capacity, mounting style, or fixture application is sufficient to surface the correct product alongside cross-brand alternatives and real-time pricing.
