The eC7CT operates from a rechargeable battery rather than compressed air. This eliminates the need to connect the tool to an air compressor and hose during operation and allows the operator to move between workstations, cages, fencing sections or field installations more easily.
A cordless tool is particularly useful where compressed air is unavailable, where long air hoses would restrict movement or where fastening work is performed away from a fixed production line.
The standard eC7CT configuration is designed around a specific 15 gauge C-ring geometry. Fastener compatibility should be checked by wire diameter, inner crown, outside crown, strip format and required closure rather than by gauge alone.
| Fastener Parameter | eC7CT Requirement |
|---|---|
| Fastener Type | Collated C-Ring / Hog Ring |
| Gauge | 15GA |
| Wire Diameter | Approximately 1.8mm |
| Inner Crown | Approximately 19mm / 3/4" |
| Outside Crown | Approximately 23.7mm / 15/16" |
| Tool Closure | Approximately 4.8–5.2mm |
| Magazine | Confirm compatible collated strip geometry; tool capacity listed up to 125 rings |
Do not substitute another 15 gauge hog ring solely because the wire diameter is similar. Larger C-rings can use different outside widths and form to substantially larger closed diameters.
The eC7CT fastener is described using both an inner-crown and outside-crown measurement. These values describe different parts of the same open C-ring and should not be treated as conflicting dimensions.
| Measurement | Approximate Size | Meaning |
|---|---|---|
| Inner Crown | 19mm / 3/4" | Opening measured inside the ring |
| Outside Crown | 23.7mm / about 15/16" | Overall outside width of the open C-ring |
| Wire Diameter | 1.8mm | Diameter of the ring wire |
| Closed Diameter | 4.8–5.2mm | Approximate loop produced by the standard eC7CT forming jaws |
The standard eC7CT is designed to form its compatible 15GA C-ring to an approximately 4.8–5.2mm closed diameter. This relatively tight closure is suitable for applications where the ring must clamp securely around wire, mesh, springs or similar components.
The combined diameter and compressibility of the materials being joined must suit the finished loop. A different closing diameter may require another tool or jaw configuration rather than simply changing the hog ring.
The eC7CT uses a 20V MAX 4.0Ah lithium-ion battery. KYA and current eC7CT product information list approximately 4,000 fastening cycles from a fully charged battery under normal conditions.
Actual battery runtime can vary with ring material, closure resistance, temperature, battery condition, operating frequency and other working conditions.
The battery is also listed with a USB output function for emergency device charging. This is an auxiliary battery feature and does not affect the hog-ring fastening specification.
Battery power removes the need for a compressor and air hose during fastening, making the tool easier to move around cages, fences, vehicles and production areas.
The collated-ring magazine automatically advances compatible hog rings into the fastening position, supporting repeated fastening without manually placing an individual loose ring for every cycle.
KYA lists a tool capacity of up to 125 rings. The actual loaded quantity depends on the compatible collated strip configuration.
The eC7CT is designed around approximately 1.8mm 15 gauge C-rings with a 19mm inner crown and approximately 23.7mm outside crown.
The standard eC7CT jaw configuration produces a relatively tight finished ring suitable for selected wire, cage, seating, mattress and mesh fastening operations.
The eC7CT is intended for professional fastening applications where compatible 15GA C-rings and a 4.8–5.2mm finished closure suit the materials being joined.
Wire cage assembly
Animal and poultry cages
Wire fencing
Wire mesh fastening
Automotive seat assembly
Automotive upholstery
Spring mattress production
Furniture upholstery
Bag closure
Selected trap and netting assemblies
For heavy gabion baskets, structural mesh or large wire bundles, verify the required ring gauge, open size and closed diameter before using the eC7CT. A 4.8–5.2mm finished loop is not suitable for every wire assembly.
Cordless operation is useful for cage and fencing work because the operator can move along a wire structure without dragging an air hose. The tool is suited to applications where the compatible C-ring can close around the combined wire diameter.
Before production use, test the ring around the actual fencing or cage wires. The closed ring should secure the connection without excessive deformation of the wire or incomplete ring formation.
Hog rings are widely used in automotive and furniture seating to join covers, listing wires, springs and frame components. The cordless eC7CT can be used where the seat assembly specifies a compatible 15GA C-ring and tight 4.8–5.2mm closure.
Automotive seat designs vary significantly. Confirm ring dimensions, closure requirement and accessibility before replacing an existing pneumatic or manual hog-ring system.
The eC7CT can be used in selected mattress and bedding operations where 15GA C-rings are used to connect springs, border wires or related components.
Mattress production can use several different hog-ring sizes and closure diameters. Match the tool to the exact bedding assembly instead of selecting it only because it is described as a 15 gauge tool.
