Allen 30mm Dynamic Blocks use the same high quality Dynamic bearing, materials and precision engineering as their 20mm Dynamic Block range. The high strength and rope friendly stainless steel ultra-strap makes them some of the strongest and most reliable ball bearing blocks in their class.

The range is available with different types of accessories including lacing eyes, hooks, swivels and cleats. The range also features a central rivet that provides great options as a tie on becket. You’ll find a 30mm block to suit most control line applications.
