GB Titanium Pro-Top Bar 25", 84DL, 3/8" .063
GB Pro-Top titanium is a durable replaceable sprocket nose bar designed and built for demanding professional users. Pro-Top is ideally suited for high-speed / high-powered Stihl chainsaws where light weight and extreme durability are required. Pro-Top bars are precision engineered from high-tech, lightweight titanium alloy steel for extra-long life and easy manoeuvrability. The Pro-Top's sprocket nose assembly supports the saw chain as it rounds the nose. This reduces friction, allowing greater chain tension and up to 25% more cutting power compared to professional hard nose bars. These wear-reducing attributes allow a considerably narrower nose profile, making the Pro-Top especially well-suited for boring and/or limbing applications. The time-tested Pro-Top nose cartridge is incredibly strong, with titanium alloy steel side- plates, precision Swiss bearings, specially-hardened sprocket and unique self-locking feature. During hardening, the nose side plates are injected with Carbon Nitride, which guarantees that Pro-Top is the hardest-wearing replaceable sprocket nose in the world. Its body is equally tough. Pro-Top is crafted from a solid, high-carbon titanium steel alloy that is specially heat-treated and tempered for super-long life. Its rails are extraordinarily strong, thanks to GB's precision groove-grinding process, and very resistant to wear and breakage as a result of induction hardening. The result is flawless, pro quality performance…cut after cut.
