When installing high tensile wire, achieving proper tension is crucial to the performance and effectiveness of your fence. Strainers, like the Donalds strainers, make tensioning wire easy.
This strainer features a spring-steel latch that catches each turn of the cog to ensure it remains safe and secure while increasing tension.
Donalds strainers are made with a square drive head on the side of the cog, making it possible to ratchet them with a variety of tools. You can use a crescent wrench, box wrench (9/16” open end or 5/8” box end / 14mm open end or 16mm box end), or strainer handle with a square cut-out slot in the handle (TFU and TFH) to add tension. The Universal Strainer Handle (TFU) will also fit over the cog and strap in the standard vertical position.
The galvanized strap along with the zinc cog makes for a long-lasting strainer that can handle years of weather and exposure to the elements.
All Donalds strainers have wider cogs with flat, non-beveled side walls. This allows them to hold more wire as well as wider material like 1” Ponyrail.
Donalds strainers are designed to be attached to high tensile wire via crimp sleeve. To install, simply slide a crimp sleeve onto the wire tail, loop the tail through the hole in the strainer strap, and join the wire back onto itself using the crimp sleeve.
