All of the Fisherman's Outfitter Custom Titanium Spreader Bars are hand-made by professional staff here at our facilities. We hand crimp every connection to ensure the strongest and longest lasting Spreader Bars available anywhere. Chafe Gear is used on all crimped connections . We use the highest quality Mustad and Owner Hooks, Momoi Leader and Momoi and Jinkai Crimps. The 36" length is preferred when using smaller baits or lighter trolling set-ups because of the reduced drag compared to the 48" Standard size.
