Automatic Dumpster Locks
Automatic dumpster locks — engage when the lid closes, released by the collection truck during normal pickup. The locking solution for routes with illegal dumping or unauthorized access problems.
What this page covers
Automatic locks (sometimes called gravity locks or self-locks) use the lid's own closing motion to engage a locking mechanism. Once closed, the lid can only be released by the collection truck's tipper arm or specific lift mechanism. No operator action is required — the lock self-engages every time the lid closes.
PRT stocks automatic locks for all major commercial dumpster brands. Most operators install them on entire routes at once to eliminate illegal dumping completely.
How to choose
Match the lock to your container type, front mount locks (P.LCKFM) are commonly used on front load containers due to the width they cover, and side mount locks (P.LCKSM) are commonly used for rear load containers since the width of the container can vary.
Verify collection-truck compatibility before installing fleet-wide. Some specialty collection equipment requires specific lock release mechanisms.
Automatic lock options

- Spring-loaded auto-locksMore positive engagement than gravity.
- Front-load compatibleReleased by standard front-load tipper arms.
- Rear-load compatibleReleased by rear-loader tipper mechanisms.
- Universal mountCompatible with most major dumpster brands.
- Replacement componentsHooks, springs, brackets for existing auto-locks.
Frequently asked questions
How does an automatic dumpster lock work?
The lock can only be released by an internal mechanism – when the dumpster is picked up by the truck the lock allows the lids to open, and when placed back down, the lock mechanism re-engages.
Do automatic locks work with all collection trucks?
Yes, auto-lock designs are standardized to standard front-load and rear-load tipper geometries. Verify with your specific collection equipment before fleet installation.
Can I retrofit an existing dumpster with an automatic lock?
Yes. Auto-locks weld or bolt on to standard commercial dumpsters. PRT stocks auto locks at multiple locations around the country for fast delivery.
How effective are automatic locks at preventing illegal dumping?
Very effective. Once the lid closes, manual unlocking requires tools or specialized knowledge. Most illegal-dumping attempts move to the next available open container.
