Straining plastic-coated wire efficiently involves securing the wire correctly and utilizing a specialized straining tool with a vise for leverage. This process is crucial for maintaining the structural integrity and longevity of your wire installations, particularly in fencing applications, by preventing sag and ensuring optimal performance.
Understanding Plastic-Coated Wire Straining
Plastic-coated wire is highly valued for its enhanced durability, resistance to corrosion, and improved safety compared to bare wire. Proper tensioning is fundamental to prevent sagging, improve structural stability, and ensure the wire maintains its intended function over time.
Essential Tools for Straining Plastic-Coated Wire
To effectively strain plastic-coated wire, gather the following tools:
- Wire Straining Tool: Also known as a wire strainer or puller, this specialized device is designed to grip and apply tension to the wire. Options include chain strainers and lever strainers.
- Vise: A sturdy vise is indispensable for anchoring the straining tool securely, allowing you to apply significant force without slippage.
- Wire Cutters: For precise cutting and trimming.
- Pliers: Useful for handling, bending, and securing wire.
- Gloves: To protect hands from abrasions and cuts.
- Safety Glasses: Essential for eye protection during wire work.
Step-by-Step Guide to Straining Plastic-Coated Wire
Achieving the correct tension is a critical factor for a durable and functional wire installation. Follow these steps carefully:
-
Prepare the Wire and Posts:
- Ensure all fence posts are firmly installed and capable of withstanding the applied tension.
- When attaching the plastic-coated wire to an end post, it is crucial that the plastic coating extends approximately 5mm into the end post. This specific placement completely conceals any exposed metal wire, offering superior corrosion protection and providing ample space to strain the wire effectively without compromising its integrity.
- Secure one end of the wire firmly to an anchor post using appropriate fastening methods, such as tensioning clips or wraps, taking care to keep the plastic coating intact.
-
Position the Straining Tool with a Vise:
- Select a suitable point along the wire, typically a few feet from the anchor or a corner post, where tension will be applied.
- Place the straining tool securely on a vise. The vise serves as a stable anchor, preventing the tool from moving while tension is applied. Ensure the vise itself is firmly mounted to a workbench or another robust surface.
- Carefully attach the straining tool's gripping mechanism to the wire, making sure it doesn't damage the plastic coating. Some straining tools are designed with specific jaws or protective pads for coated wires.
-
Apply Tension Using Lever Action:
- With the straining tool firmly attached to both the wire and the vise, pull the wire using the lever action of the straining tool.
- Gradually apply tension by operating the lever, which progressively draws the wire tighter.
- Continuously monitor the wire's tension. The objective is to eliminate slack and achieve a taut, firm state without over-stretching, which could damage the wire or posts. For extensive runs, you may need to strain in sections or use multiple strainers.
-
Secure the Wire and Release Tension:
- Once the desired tension is achieved, secure the strained wire to the next post or anchor point. This can involve using staples, tie-offs, or tensioning clips, always being mindful not to compromise the plastic coating.
- After the wire is securely fastened, carefully release the tension from the straining tool.
Practical Tips for Effective Straining
- Protect the Coating: Always prioritize the integrity of the plastic coating. If your straining tool doesn't have specialized jaws for coated wire, use a protective material like a piece of rubber or thick cloth between the tool and the wire.
- Achieve Even Tension: Strive for consistent tension across the entire length of the wire. Uneven tension can lead to localized sagging and premature wear.
- Assess Tension: A good way to gauge tension is to gently push down on the middle of a wire span. It should feel firm, offer significant resistance, and return quickly to its taut position.
- Prioritize Safety: Always wear appropriate personal protective equipment, including gloves and eye protection, to prevent injuries when working with wire.
Choosing the Right Straining Tool
Selecting the appropriate straining tool is vital for an efficient and successful installation.
| Tool Type | Description | Ideal For |
|---|---|---|
| Chain Strainers | Utilize a chain and a gripping mechanism, often with a ratchet, to pull the wire. | Heavy-duty fencing, long runs, and high-tension requirements. |
| Lever Strainers | Directly grip the wire and use a lever arm to apply tension. | Shorter fence runs, lighter gauge wire, and quick adjustments. |
| Permanent In-Line Wire Strainers | Integrated into the fence line, allowing for easy re-tensioning over time. | Maintaining tension in existing fences, quick adjustments to sag. |
For general plastic-coated wire fencing, a robust lever or chain strainer used in conjunction with a vise offers excellent control and ensures precise tension application.
Maintaining Your Strained Wire Fence
Regular maintenance will extend the life of your plastic-coated wire fence:
- Inspect for Sagging: Periodically check for any slack. New fences may require re-tensioning as materials settle.
- Repair Coating Damage: Promptly repair any nicks or cuts in the plastic coating to prevent the underlying wire from corroding. Repair kits are available for this purpose.
- Check Fasteners: Ensure all staples, ties, and clips remain secure and are not damaging the wire's coating.
By adhering to these detailed guidelines, you can effectively strain plastic-coated wire, ensuring a durable, secure, and long-lasting installation.
