STANDARD ROLLER TIP-TOPS. The Most Widely Used Roller Tip-Tops In The World. With universal applications for all types and standard sizes of saltwater trolling and deep water rods, our Standard roller tip-tops are now equipped with our modified rollers and feature AFLON bearings. Designed to match up with both our Heavy Duty and Regular roller guide sets, they are available in both large head (L) and small head (S) versions in many sizes. The L models offer extra knot clearance, as with the 112L, 114L and 116L, our most popular models for stand-up style tuna rods.
