That's an excellent and very specific question! It addresses a common urban dilemma: how to keep a trash can accessible yet secure in a public or semi-public space. The good news is, yes, models designed for this exact purpose do exist, and there are also great adaptable solutions.
The most direct answer is to look for lockable or anchorable outdoor trash cans. These are often marketed for use in parks, apartment complexes, or city streets where theft or unauthorized movement is a concern. Many commercial-grade bins come with integrated metal loops or reinforced handles specifically for a chain or cable lock. You would simply thread your chain through this loop and around the fence post before locking it.
If you can't find a model with a built-in loop, a standard metal or heavy-duty plastic bin can often be modified. The key is to carefully drill a hole in a non-critical, reinforced part of the bin's back or side. Then, use a sturdy padlock to secure a chain through this new hole and your fence. Always ensure this doesn't compromise the bin's structural integrity.
When searching online, use terms like "lockable outdoor trash can," "anchorable garbage bin," or "public litter bin with security chain." This will lead you to products from commercial and municipal suppliers that are built for durability and security, perfectly solving your chained-to-a-fence need.
