Winding checks are used to create a nice tight transition between gripmaterial and blank. Choose a size that leaves little space between check and blank. Fill this space out with a small strap of tape and apply little epoxy glue before sliding the check in place. The pvc CK checks can stretch out a little so it works best to pick a size equal, or a fraction smaller than the blank. Shock rings can be used as a check or to protect blank slip and spignot connections.
