Tariff Updates

We are observing how the tariffs are behaving. Lots of our products are imported from Europe and some of the manufacturers are not providing heads up about price increases. We will do everything in our power to hold the best prices, but please consider that in these uncertain times we may be forced to increase the prices without previous notification.

We really appreciate your understanding and look forward to working with you.

What does this mean for you?

  • Some imported products may show a higher price than usual.
  • Prices may change as shipping rates adjust globally.
  • We are committed to providing the best possible pricing and transparency at all times.

How we’re handling it:

  • We only adjust prices when absolutely necessary.
  • We continuously monitor shipping rates and update pricing accordingly.
  • We’ll clearly notify you if a product is affected by tariffs.

Questions? Feel free to contact our team for any clarification or assistance.

      A Good Choice for Wire Antenna Support Lines

      Posted by Merrill Hiscock on May 20th 2017

      These blocks meet or exceed my expectations. They are small and light, and the pulleys turn smoothly under load. The blocks are a perfect fit for the 5 mm (3/16 inch) Dacron cord that I am using to suspend the ends of a 240-foot wire between two tall trees. The blocks have survived the considerable tension applied to them during the antenna-installation process. Although I cannot predict how durable they will be over a period of years, I am confident that they will not be the first component of the antenna system to fail.
