Calculator tips:
* Enter all form values in inches. This form will accept values in decimal (35.75) and fractional (35 3/4) form. Use whichever is most convenient for you.
* To maintain a valid warranty and fire label, there must be at least 5" between the lock prep and lite cutout. If using Timberstrand core, there must be a minimum of only 2" between lock prep and lite cutout to keep the warranty valid (fire label still requires 5" margins).
* If you get an error message you do not understand, try resetting the form and re-entering your information. Also, make sure all boxes have dimensions in them.
