Most service trucks have an arm that hooks to the top and one that hooks on the bottom so the cart does not fall into the truck, best to always check with your hauler to insure proper fit as the Titan's design is not typical to most automated trash trucks. Most of the time the hauler will need to pull the trash manually from the top of this bear proof trash can. The Titan is offered in a 95 and a smaller 65 Gallon model and has an optional paddle latch feature that allows the lid to automatically lock upon closing. The Titan bear resistant trash can also have an optional drain hole feature to easily release any water that may enter into the can. This metal powder coated bear proof garbage can is the only metal bin tested and approved to effectively keep out any gnawing animals while providing for a smaller profile enclosure without having to purchase a more expensive metal enclosure or bear proof dumpster. Secure carabiner clip or for easy open and closure add our optional and most convenient paddle latch.
