Wire tensioning with a come-along or tensioner

The come-along applies mechanical advantage to pull wire mesh until it reaches a specific tension. Every observation from fence company edmond ok jointhehoop has logged shows the same thing regarding wire sag. A local company in Edmond, OK, must ensure that the tensioning process does not pull a post out of its concrete footing. Proper tensioning prevents the mesh from drooping or becoming loose over time.

The Physics of Wire Tensioning

Pulling wire requires a leverage tool like a ratcheting come-along or a manual wire strainer. You hook one end of the tool to a terminal post and the other to the wire mesh. As you crank the lever, the tool shortens the distance between the two points. This mechanical action stretches the wire into a straight line. If you pull too hard, you risk bending the terminal post or cracking the concrete footing. You must monitor the tension with a gauge to hit the specific pounds required for the material. This is especially true for heavy gauge chain link or high tension wire used in agricultural settings.

Securing the Anchor Points

The integrity of the tension depends entirely on the stability of the post. A terminal post must be set deep, often below the frost line, to resist the lateral pull of the come-along. If the post is not braced, the tensioning tool will simply pull the post toward the center of the run. We use heavy gauge steel for these anchors. Once the wire is pulled tight, you lock it into place using crimps or tension bands. This prevents the wire from snapping back when the tool is released.

Managing Material Deflection

Different materials react differently to mechanical pulling. While a metal mesh stays relatively stable, a wooden privacy fence or a shadowbox style setup relies on the structural rigidity of the rail and the picket. You cannot use a come-along on a wood panel. For metal fencing, such as aluminum or wrought iron, the tension is managed through specific hardware. If you are working with a chain link setup, the tensioning tool is the only way to ensure the fabric is drum tight. Tight wire keeps the mesh from sagging under its own weight or under the weight of wind.

The Role of Hardware and Fasteners

Proper tensioning is useless if the hardware fails. After the wire is pulled, check every latch and hinge on the gate to ensure the tension from the run hasn't shifted the gate frame. The wire should be secured with heavy duty bands that won't slip under load. If the tension is uneven, the entire line will eventually fail. Check the connection points at every post to ensure the wire is seated correctly in the clips. A loose wire is a failed installation.
