Harken 224 Low-Friction Micro blocks with attached shackle are compact and lightweight. They are ideal for 3/16” dacron support line for all dipoles and doublets. These high-quality blocks are considered the best available and stand up to all types of weather conditions. Mine have been in use at my QTH in the mountains of Vermont for over fourteen years and have not given me one problem whatsoever. Buy the best and stay away from the cheap hardware store steel ones that rust and seize up over time.
