SR-2 Jib RollerThe Forespar; SR-2 Jib Roller with fit shrouds from 3/16” thru 3/8” wire diameter. Use the proper size pair of insert liners according to the table below:3/8” wire – use no insert5/16” wire – use #1 inserts9/32” wire – use #2 inserts¼” wire – use #3 inserts7/32” wire – use #4 inserts3/16” wire – use #5 insertsThe Jib Rollers may be placed just above or below the spreader tips; however, installation will be easier if located below the spreaders. In this instance, you can pre-assemble the parts while on deck and reduce the possibility of losing parts while hanging in a boatswain’s chair. Have a 3 inch piece of masking tape within handy reach (stick it to the shroud).Select the proper inserts, place them into the two halves of a hub and fit them around the shroud. Use the tape to loosely hold these parts together. Note that the hubs have two clearance screw holes at one end. Match these with the smaller holes at the other end of the other half. It is important that the mating faces of the inserts are parallel with the faces of the hub halves. Install the four screws supplied, tightening only to the extent that you can still slide the hub assembly up the wire shroud. Now remove the tape. Next, install the rollers. Note that one half of each roller has clearance holes for the two screws. Mate these halves that don’t have clearance holes. Run these screws tight. Now slide the Jib Roller to the desired position on the shroud and finish tightening the four hub screws until the hub interfaces are fully closed.
