A Message from our CEO

In an effort to keep all our customers informed, we want to share with you the following updates.

We are committed to keeping our employees, customers, and communities safe. In the wake of this pandemic, we took swift action to mobilize a significant number of our global team to remote working arrangements while enhancing our cleaning procedures and securing our production facilities to prevent the spread of the virus COVID-19.

As we continue to work through this pandemic, our core values have shone through, and we remain operational and dedicated to meeting the expectations and needs of our customers. Very early on, we increased our inventories, and we are in regular contact with our suppliers to monitor their status. We have maintained a high level of production, and our supply chains are meeting our requirements. However, we do prioritize firm orders above forecasts. Because this is a very fluid situation, we encourage you to make sure you have orders in place with us to carry you through these unusual times.

We will continue to keep you updated as this situation evolves. Meanwhile, stay safe and take care.


Gregory A. Woods
President & CEO
