Harken 234 Low-Friction Micro Block with Shackle
Description
Harken 234 Low-Friction Micro Block 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.
The shackle on the 234 allows you to disconnect the block to work on your support system or to lower the antenna down, without unthreading the entire length of dacron line.

Harken 234 pulley
I've only had this pulley up in the air for a week now. During deployment, it was pulled into thick branches and leaves a few times before landing where it really needed to be. Never did the rope get blocked or kinked. The pulley still works right now. I'm told this pulley will not rust, but time will tell that answer for sure in the future.

Harken 234 Micro Block
Micro Block worked great. Was able to support my True Ladder Line Zepp antenna with weight allowing expansion during windy conditions. Unit is high quality. Thanks!

Shackle
This is a great shackle, works great for the Dipole installation I used it for . Handles any weather here in Michigan with no problems. I highly recommend these shackles.
