KYA C2 is a heavy-duty pneumatic C-ring plier designed for large-format C-rings used in selected mattress production, wire mesh, fencing, industrial netting and gabion-related assembly applications.
The tool weighs approximately 3.6kg and has a 125-ring magazine. KYA lists compatibility with approximately 63mm crown C-rings made from 2.0mm wire, with a finished closure range of approximately 17–21.5mm.
The C2 is substantially larger than common upholstery hog ring tools and is intended for applications where a larger ring opening and larger finished closure are required. Buyers should confirm the complete ring dimensions, wire diameter, material and required joint performance before ordering.

The C2 is designed for a substantially larger C-ring than standard upholstery hog ring guns. KYA lists an approximately 63mm open crown, allowing the ring to surround larger wire bundles, mattress components, mesh joints or other industrial assemblies.
Because 63mm is not a common small-format upholstery ring size, replacement fasteners should be selected using the complete dimensional specification rather than by product name alone.
KYA specifies approximately 2.0mm wire for the C2 fastener system. This is heavier than common 16GA and 15GA upholstery hog rings, which typically use approximately 1.6mm or 1.8mm wire.
Wire diameter affects both joint strength and tool compatibility. Rings with the correct crown but a different wire diameter may not feed or close correctly in the C2.
The C2 is listed with an approximately 17–21.5mm finished closure range. This allows the large C-ring to be formed around different wire bundles or components within the tool's supported geometry.
The correct finished closure should be selected according to the actual material being joined. Excessive compression can deform wire or mesh, while an oversized closure may not provide sufficient retention.
The C2 magazine holds up to approximately 125 compatible C-rings, reducing reload frequency during repetitive production or assembly work.
Correctly collated rings should be used to maintain reliable feeding. Damaged strips, deformed rings or incorrect wire dimensions can affect magazine operation and final closure.
The pneumatic mechanism supplies the closing force required to form large 2.0mm C-rings around compatible components. This reduces the manual squeezing force required compared with hand-operated pliers for large fasteners.
Tool performance still depends on air pressure, ring dimensions, jaw condition and the resistance of the joined materials.
KYA specifies a high-strength alloy steel muzzle for the C2. The muzzle and closing jaws guide the large C-ring and control its final shape during each fastening cycle.
Inspect the jaw surfaces periodically for wear, cracking or misalignment. A worn muzzle can change the finished closure and cause inconsistent joints.
The C2 weighs approximately 3.6kg, so it should be treated as a heavy industrial pneumatic tool rather than an ultra-light upholstery plier. The balanced body and rubber grip are intended to improve handling during repeated fastening operations.
For continuous work, workstation height, hose routing, tool suspension and operator position should be considered to reduce handling effort.
KYA lists mattress manufacturing as a primary C2 application. The large ring opening can be used around compatible spring, wire and frame components where a smaller upholstery C-ring does not provide sufficient opening or finished diameter.
The source specification references applications involving approximately 25–30mm mattress spring assemblies. The actual ring and closure should be tested against the spring and wire combination used by the mattress manufacturer before production.
Large C-rings can be used to join compatible wire mesh, fencing and industrial netting where the 63mm ring opening and 17–21.5mm closure suit the material bundle.
Ring material and coating should be selected according to indoor or outdoor exposure, corrosion requirements and the wire material used in the assembly.
Pneumatic C-ring tools are widely used to connect gabion panels, lids and adjacent baskets. The C2 can be considered for gabion-related assembly when its 2.0mm ring wire, 63mm crown and finished closure meet the basket manufacturer's connection requirements.
Gabion fastener requirements vary by basket design and project specification. Engineered or specification-controlled gabion systems may require larger-diameter ring fasteners, specific coatings, defined ring spacing or tested panel-to-panel connection strength.
For example, some ASTM A975-based double-twisted gabion specifications use approximately 3.0mm ring fasteners. Do not assume that a 2.0mm C2 ring automatically satisfies every gabion project requirement.
| Check | Why It Matters |
|---|---|
| Ring Wire Diameter | Must meet the basket or project connection requirement. |
| Ring Material | Should be compatible with galvanized, Galfan, PVC-coated or stainless mesh systems. |
| Open Crown | Must fit around the panel wires or selvedge wires being connected. |
| Closed Geometry | The finished ring must retain the connected wires without excessive looseness. |
| Fastener Spacing | Engineering specifications may define maximum spacing between rings. |
| Connection Strength | Specified gabion systems may require tested panel-to-panel connection strength. |

KYA lists an operating range of approximately 4–7 bar / 58–102 PSI for the C2, together with an 8mm air inlet.
Use regulated compressed air and ensure that the hose and fittings can maintain adequate pressure at the tool during repeated operation. Long hoses, restrictive fittings and insufficient compressor capacity can reduce closing performance.
If the ring does not close correctly, verify ring dimensions, jaw condition, feed alignment and air supply before increasing pressure.
Inspect the large closing jaws and muzzle for wear or damage.
Keep the magazine and feed path clean.
Use only correctly sized and collated C-rings.
Do not load bent or damaged fastener strips.
Check air hoses, couplings and fittings for leaks.
Disconnect the air supply before clearing jams or servicing the tool.
Replace worn jaws when finished ring geometry becomes inconsistent.
