E+G EWN-LP wing nut with retaining chain.
The elastic fork, housed in the groove of the wing nut can turn freely. The coiled ring connects the fork to the chain. Suitable where it is necessary to prevent the loss of the wing nut. For applications in which the fixing of the chain is at a position higher than that of the wing nut, it is advisable to leave it with slack movement to prevent the ring from touching the wing nut.
