The A2024 is our go-to triple sheave, low friction, fast rolling, small pulley. It’s lightweight and strong, making it ideal for dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines.

Triple blocks are generally used in systems such as cunninghams or vangs, to give a larger purchase system.

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

Ultra-Strap – Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Becket – Our 20 & 30mm blocks offer a large central rivet which not only reduces the overall weight but also offers a rope friendly attachment, perfect as a tie-off point when being used in a cascade system.

Great choice!
Color: #14R - Pack of 21 (20 Blades + 1 Handle)
A little difficult to get the blade on and off but perfect for dermaplaning the face.

The best!!
These are literally the best dermaplaners I have ever purchased! I feel like I just went to a professional. Don’t waste your time buying anything else other than this because it works the best!

At least they are sterile
These are funny being advertised as dermaplane because they are packaged as scalpels. The 5 scalpels are individually wrapped, and labeled sterile. As the price indicates, they are on the cheap side. Which is fine, they work, but they aren’t terribly sharp so you have to scrape a bit harder than preferred. For dermaplaning I prefer the schick ones as they have tiny serrations which cut the hair better than anything else I have found so far.
