All Plastic "FRICTION" Cord Lock. Sold in units of 25pcs.
An all-plastic cord lock made from Acetal for a true, "wet-use" rust proof solution. Acetal has very reasonable heat resistant properties too.
It is 11.5mm long and has an external diameter of 13mm. It is advised as 3mm internal which should be taken as a guide to the approximate cord size. This "friction" cord lock is shown on our B423B cord. It can also be used with narrower/multiple cords also.
