PLEASE NOTE: COVID has interrupted global supply distribution chains resulting in unprecedented delays on incoming door and dock industry products. The result is limited availability of many products, two to three month delays on incoming shipments, and an inflationary rate of over 100% in 2021 on many of our core products such as springs.
PLEASE NOTE: DUE TO COVID-19 SHIPPING TIMES ARE NOT GUARANTEED, EVEN ON NEXT DAY AND SECOND DAY SHIPMENTS. NORMAL TRANSIT TIMES DO NOT APPLY.
PLEASE NOTE: Due to cone shortages, we no longer provide springs with the end cones on the 1 3/4" and 2" inside diameter springs unless you are willing to wait for two months. If you need the larger inside diameter springs with or without cones, there will be a two month delay on these as well. If you are willing to wait two months for your springs, please note that in the comment section of your order. We deeply regret the hardships this will create for many of our customers.
