The Smooth Puller lock from CRESTA is equipped with a PTFE wheel, so that the elastic can be pulled out of the rod almost frictionlessly during the fight. This facilitates the “pull” process and extends the life of the elastic. Mounting this puller lock in the rod is very easy, thanks to the completely round shape (10mm) that has to be drilled into the rod part. Only do this in a designated and reinforced puller zone. Then place the lock with the wheel facing the top in the hole and glue it firmly with the second line.
