Strain Plate
A Curved Strain Plate provides essential protection for wood utility poles against guy wire damage in wrapped installations. It works in conjunction with guy hooks to create a reliable bearing surface, preventing deterioration of the pole’s wood fibers. They are typically installed using 2-4 plates per pole, depending on the pole’s diameter.
These protective plates are commonly used in utility pole installations where guy wires require secure anchoring points. The plates integrate seamlessly with guy strain insulators of various strength ratings, from 15,000 to 80,000 pounds, featuring different UV protection options like veil and silicone coatings. They are particularly effective when used with standard pipe installations near sidewalks and buildings where space constraints exist.

Frequently Asked Questions (FAQ)
What is the purpose of a Strain Plate?
Strain plates are used in wrap-type guying applications with guy hooks to provide a bearing surface for the strand, preventing damage to the wood fibers of utility poles. They are essential for protecting pole integrity during guy wire installation.
What are the standard dimensions of a Strain Plate?
The standard strain plate measures 6 inches wide by 7 inches long with 13 gauge thickness. It features a 4½-inch radius curve and includes mounting holes for secure attachment to utility poles. More dimensions can be customized.
How many Strain Plates are needed per pole?
Depending on the pole diameter, 2-4 strain plates are required per pole for proper installation and load distribution.
How are Strain Plates attached to the pole?
Strain plates are constructed with four 3/16-inch nail holes for secure attachment to the utility pole. They are typically installed using galvanized nails or appropriate fasteners.
What is the curve specification for Strain Plates?
Strain plates are curved on a 5-inch radius to properly conform to utility pole surfaces and provide optimal load distribution for guy wire applications.
