We recommend the use of a 1/2 inch crown stapler but a 1/4 inch crown stapler will also work.

How To Measure Your Door

Width of Door - Measure the width at the bottom, halfway up and at the top of the door and use the widest dimension you have. NOTE:  IF THE WIDEST DIMENSION IS AT THE BOTTOM OR CENTER YOU MAY HAVE TO TRIM THE SUSPENSION TRACK TO FIT YOUR OPENING AT THE TOP OF THE DOOR AS TRACK LENGTHS ARE MADE TO THE ORDERING WIDTH. This can be done with a hacksaw.

Height of Door - Measure from the top of the finished floor to the point where you are going to attach the track. Measure at 3 different points across the width of the opening and use the tightest dimension you have. Note: If this dimension differs more than 1/2" across the opening call to discuss how to arrive at an acceptable dimension.
