Yes. For trash can factory models designed for public plazas, we offer several key-lock lid options engineered to prevent unauthorized dumping, reduce tampering, and keep waste secure while still giving maintenance crews quick access. Available choices include cam locks, quarter-turn key locks, hidden hinge-lock systems, and tamper-resistant latches. Lids can be configured with single or dual locks, keyed alike or keyed differently, and with optional master-key access for municipal staff. We can customize the lock housing, keyway, and stainless-steel components for outdoor durability, weather resistance, and corrosion protection. Public plaza models often need a balance between security and convenience, so we also supply ergonomic key handles, lock covers, and tether chains to prevent lost keys. For high-traffic areas, we recommend reinforced lid frames and lock brackets that resist forced entry. Our factory supports OEM and ODM orders, allowing you to choose standard key-lock kits or fully custom locking lids based on your bin dimensions, material, and opening mechanism. If you need samples, technical drawings, or a quotation for key-lock lids on public plaza trash cans, please share your model number and target quantity.
