Today's post is all about halyard. We couldn't help but stop here and show some symptoms of halyard in desperate need of replacing. Flagpole rope (halyard) is tough to judge. There are a lot of thicknesses, sizes, materials, and types. We like to think PH10 or NWCH10 is always a good bet. On FlagDesk, we have a sorting tool you can use to filter your products down by specific requirements. The 10 series halyard is 5/16" thick, this thickness fits through most pulley systems while also having enough of a diameter to withstand all types of weather.
Look for signs of fray, ripping, or in this case, the housing is completely eroded and all that remains are the guts of a piece of rope not designed for a flagpole in the first place. You want woven rope, the weave should be unilateral. This cause the entire rope to shrink and expand in varying weather conditions. This will prevent shrinkage. Shrinkage from other ropes can cause the halyard to be so tight on the flagpole, the only way to get the flag down is to cut the rope.
You may save money today on rope from the hardware store but you'll be sorry when you have to cut the line to get the flag down.
