For sleeving Forespar® spinnaker pole end-fittings. For use on larger diameter tubing, and other applications.
"ABOUT ULTRA STYLE END FITTINGS Proper attachment of Ultra style end fittings to carbon & aluminum tubes. Forespar® Ultra Series composite ends requires careful attention to fasteners style and placement. The Ultra material is extremely strong and durable at half the weight of their aluminum counterparts but require the use of pan head machine screws-not rivets or glue-for proper attachment to carbon or aluminum tubing.
Drill and tap the holes. Placement of the fasteners is also critical to the strength of the attachment to the pole, especially when an adapting collar (i. e., 2' ends on 2.5"" tube) is used. The S/S PHMS (pan-head machine screws) must be placed so they engage the adapting collar and the core of the end fitting to the tube. The fasteners for aluminum tubes should be placed _""back from the end of the tube onto the (flange) collar on 2.5"" and 3.5"" sizes and the basic ends without collars on 2"" & 3"" sizes. Use a minimum of 4) 10-24 PHMS on ends 2"", 2.5"" and 3"" and 5) on 3.5"" to 4"". 6) or more -20 PHMS may be needed on larger diameter tubes. On carbon tubes, place the fasteners_"" backfrom the end of the tube. Be careful not to drill into the spring/piston housing on either style end (UTR & UXP) and not to hit the ""set screws"" on the sides (left and right side of the core) of the UTR style ends.
Be sure to offset your holes pattern to clear these components and double check before you drill and tap! On carbon tubes, be sure not to over tighten and stress or crack the fiber laminate. If the carbon tube does not fit to the end fittings tight, wrap 2"" masking tape around the core (bury of the end) until you achieve a snug fit."
