This will depend on the options chosen for handleset preparation when configuring your door.
If you chose a double bore, 2-3/8" backset you will need a standard tubular handleset. These can be found off-the-shelf in any hardware or home improvement store. We bore for tubular at a 2-3/8" backset unless otherwise specified on your order. We provide a standard 2-1/8" bore (double for handle and deadbolt), 5-1/2 center-to-center. This is very standard.
If you chose multipoint, you will need to purchase multi-point handleset trim. Your trim will need to be compatible with Configuration 2 American Cylinder Above the Handle, 3-5/8" Center-to-Center.
