There are a number of advantages of installing Markar pin and barrel continuous hinges over geared hinges. Most importantly, pin and barrel hinges can hold significantly more weight and are fire-rated out of the package. Additionally, pin and barrel hinges are held together with a stainless steel Teflon-coated rod creating a strong, monolithic, free-moving assembly. Conversely, geared hinges are held together with an aluminum cap, which can loosen and cause non-alignment of gears – leading to premature failure.
