What Is CAN-LOK?
CAN-LOK is the original can overseal ring — precision-engineered from high-grade, durable HDPE to lock and secure paint can lids tightly to the can body, providing a reliable barrier against leaks and spills during storage and shipping since 1993.
Designed with 3 points of contact, CAN-LOK prevents paint from migrating out of the can while remaining easy for consumers to remove with a flat-head screwdriver or standard household pliers.
Applied quickly with a standard paint can closer or a rubber mallet — no special equipment needed, saving time on the production line.
Why CAN-LOK
Three points of contact prevent paint from migrating out of the can while keeping a reliable seal throughout storage and transit.
Mechanically locks the lid in place, preventing accidental opening from vibration, pressure changes, or impacts during shipping.
Manufactured from durable, high-grade HDPE delivering consistent performance and resistance to paint chemicals and pressure.
Tested and certified to meet UN hydrostatic pressure requirements of 95kPa — essential for compliant storage and transit.
