Allen 30mm Dynamic Blocks use the same high quality Dynamic bearing, materials and precision engineering as the 20mm Dynamic Block range. The high strength and rope friendly stainless steel ultra-strap makes them amongst 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.
Back to back blocks have many uses including attaching the tack line to the halyard on gennaker systems with a self launching pole.
