ACO Environment — Oil Separator Alarm Systems
When selecting the grate there are a couple of factors that have to be considered, including the load classification (resistance to failure), slot pattern (water intake), material (corrosion resistance, etc.), locking (making grate captive to channel), and aesthetics (finished look). Click here for further information on grate selection.

DrainLok grates provide continual access to the channel and features the locking mechanism as an integral part of the grate.
QuickLok® grates require a separate locking bar and use a bayonet fitting attached to the grate that is spring-loaded into the bar. These grates are ideal for extra security.

DRAINLOK - BOLTLESS & BARLESS LOCKING SYSTEM
Factory-fitted locking device removes need for bolts and bars and improves channel hydraulic capacity. The DrainLok mechanism clips into channel edge rail for rapid installation. DrainLok grates are fit with an anti-shunt mechanism that restricts unwanted grate movement when installed, improving durability and longevity of the system.
Push down or stand on grate until it clicks into position.
Position grate onto channel and align anti-shunt detail with recess in rail.
To remove first grate, insert grate removal tool into slots at end of grate, pull up sharply. Remaining grates can be removed by hand.
QUICKLOK® - BOLTLESS LOCKING SYSTEM
Comprised of either a glass nylon stud or steel pin fitted to grate and a removable QuickLok® bar in channel, QuickLok® locks grate to channel by aligning stud over locking bar and applying pressure until they snap together. With no loose bolts or bars, QuickLok® provides a highly secure boltless lock that is still easy to take apart for maintenance and cleaning. This saves time and money during installation.
Locate locking bar in channel wall recesses by rotating clockwise.
Use hammer to tap bar into place so that serrated ends grip in recess.
To install grate, align QuickLok® stud directly over locking bar.
Push down or stand on grate until it clocks into position.
To remove first grate, insert grate removal tool into slots at end of grate, pull up sharply. Remaining grates can be removed by hand.
To remove bar, insert screwdriver into hole at end of bar and lever back serrated end, rotate bar free.
