Flexible Furler vs. Reefer: Flexible Furlers feature a one-piece plastic luff extrusion (vs. the Reefer's aluminum luff sections). CDI has been producing the Flexible Fuler since 1989.

Identifying your Flexible Furler : Simply measure the diameter of the "cup" (the part around the spool which keeps the furling line from falling off).

There are a few Flexible Furlers that have a continuous line drive rather than a spool. To identiy these by size, measure the width and thickness of your luff extrusion.

Product Changes: From 1989 to 1992, the Flexible Furler "cup" was made of aluminum. Aluminum cups had a small hole where the furling line exits the spool. From 1992 to 1994, the cups were made of black plastic. From 1994 onward, stainless steel cups have been used. They have a large "picture window" exit hole for the furling line.
