The same NLGI GC-LB certified grease as the cartridge, in a 14.1 oz canister. The difference is how you get it out: a cartridge goes in a grease gun, a canister is for hand packing a bearing, which is what most people actually do when they pull a trailer hub apart.

Worth having both if you tow. Hand pack the bearing from the tub, then use the gun for the zerks and the coupler.

GC-LB is the wheel bearing and chassis certification, -45°F to 450°F, saltwater resistant, and it will not separate sitting on a shelf over winter.
