SHIPPING DELAYS: There are ongoing issues moving product both locally, around the USA, and the globe, it is essential that you take this into account when ordering materials, tools or product over the next 3 to 6 months, especially if you run on a "just-in-time" basis. There are still shipping delays for some products in the supply chain for critical construction products. Please make sure to order items well in advance to make sure your order arrives in time for your next job. Most manufactures have already implemented “force majeure” and placed additional surcharges and fees to secure their raw materials. Conspec is filling online orders as soon as possible, however with the supply chain broken, and only receiving partial inventory from manufactures with increased demands the shortages are out of our control. We apologize for the inconvenience and thank you for your patience in these challenging times.
