"Hardware" spreader block to carp net.
Same problem as Kenny Mac. Brass thread to a nylon spreader block pulled out of its setting lifting a wet net out of the water (with no fish in it). Also had to replace the spreader block with a metal one (from a cheaper older net this one was bought to replace!). Hope Hardware have since 're-designed' so that it lives up to their brand name and is fit for purpose. Good job I always carry a second net made up in case of multiple catches as 20 minutes later the net was needed for a 17lb common!
