Dear Trim-Lok Customers:

Like many companies in California, Trim-Lok is exempt from the current "California Shut-Down Guidelines” under the section that covers “essential activities” as listed under “manufacturers and suppliers.”

Many of Trim-Lok's seals are used in such essential, critical parts and equipment in the following categories: Temporary Housing, Air Filters, Ambulances/Emergency Vehicles, Lab Testing Equipment, Medical Devices and Equipment, Military Vehicles & Equipment, just to name a few.

To confirm, Trim-Lok remains open and fully operational at its manufacturing facility in California.

I’ll continue to keep you updated and informed as the Country continues to move forward through the Covid-19 situation.

Thank You,
Dan Whitener
Vice-President and COO
