Customer Service & Support

We make every attempt to answer all email questions. However, we are still a small business so be patient if a response is not forthcoming within a few hours.  We build all units on an as ordered basis so please note the current production time shown on our Homepage before anticipating a shipping notice.

To contact us, you can send an email to or call between 9 am and 5 pm Central time Monday thru Saturday at 817-832-7197.  We'll be glad to take a phone order, discuss technical issues/designs or custom modifications you might need.

Please keep in mind that we are a full time business so as much as we would like to chat, we may need to keep the conversation "crisp".  If for some reason there is no answer, please leave a message as we return all calls.
