Start by emailing a photo over to one of us. We will get right back to you with a dimensions form.
The dimensions form will be our way of determining a functional kit design specifically for your panel. It will also serve as a way for us to check our inventory to see if a design was already made for the panel!
Once we have your dimensions sheet expect a 2-3 week lead time to design, construct, & deliver your Interlock kit
How is pricing structured for custom Interlock Kits?
- Pricing will fluctuate based on the amount of material used when building the Interlock Kit.
- Another factor will be the complexity of the design or the amount of time needed to go into designing the perfect manual transfer switch for your panel!
