We have a new brand on the site called MaxGrade. This brand offers great quality forged brass door hardware as well as a great price no matter the item. The hardware is easily installed and fit standard door preparation. It's super easy to order MaxGrade hardware. Some brands require measuring backset sizes, door thickness and lots of times you have to find out if your door is a right hand or left hand door. With MaxGrade, you don't have to do all that. The backset is adjustable, the door thickness fits standard door preparation, and the handing is interchangeable, meaning you can switch it from left hand to right hand and vice versa. All you will need to know is if you want a handleset you can choose between a single cylinder handleset (keyed cylinder on outside, thumbturn on inside) or a dummy handleset (non functioning handleset or stationary handleset). If you are interested in a knob or lever, choose from passage, privacy, keyed entrance or dummy functions. If you need help determining what function you need look under order help next to the description tab on the item page. If you are interested in a deabolt, that's super easy, most people order the single cylinder deadbolt which is a keyed cylinder on the outside and thumbturn on the inside. Some people do like the option of a double cylinder deadbolt which is a keyed cylinder on the outside as well as on the inside, so you would need a key to lock the door from either side. Double cylinders are used on door that have partial glass on or around the door, so in case an intruder were to break the glass, they would need a key to unlock the door from the inside. After you have chosen your item(s) and function(s), all you have left is to choose a finish. Simple as that.
