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.

Redesigned with a sleek look the Black Magic Air blocks has their same unique, performance-packed engineering as ever.

Feature Torlon® roller bearings which stay parallel for low-friction efficiency housed in a center cage; the block carry some of the highest loads imposed by running rigging.

Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings. Blocks are easily disassembled with a single hex wrench. Dissimilar metals are isolated to minimize corrosion.

Either metric or imperial flathead fasteners may be used for mounting and are not exposed.

Use for:
  • Genoas
  • Spinnakers
