Narrow's Marina should have them... They we be about $5 more than lead. If they don't have them, they will special order at no extra cost.

Make sure to buy a few extra so you have them on hand...

Don't use them for fishing deeper than normal-blow back will kill you..

You could probably get away with a window sash, but they don't offer much more than probably 8 pounds. I used them for meatlining back in the day.

To break connectivity, I use 36-42 inches of parachute cord between 300# barrel swivel.. Much cheaper than that piece of junk green gel cord...
