Step 3 - Depth of Dovetail
Using a tape measure, straight edge and level -
A.) Measure the distance from the crown of incline from the inside edge of where the door/ramp closes (FRONT TO BACK MEASUREMENT).
B.) If you have a screened in Garage and the track of the screen exceeds 2”X6” (2.00”: SIDE TO SIDE MEASUREMENT and 6.00”: FRONT TO BACK MEASUREMENT), then the measurement will need to be taken from the backside of the screens track. Using the same instructions as above: Measure the distance from the crown of incline from the “backside of the screens track”.
