Steve in Closers
The two most common ways to mount a door closer are either parallel arm or standard arm. The parallel (PA) arm type will mount on the push side of the door. The standard (STD) type will mount on the pull side of the door. Most door closers will be packed with the boot screwed onto the arm for STD mount and the PA bracket in the box as a loose item to be installed if needed. On outswing exterior doors, you would obviously install it as a PA type to keep the closer out of the weather.

Steve in Hollow Metal Doors
Replacing a hollow metal door in an existing hollow metal frame? Keep in mind one size does NOT fit all! Different manufacturers have their hinge and lock preps in their doors at different locations. So make sure to measure each hinge location from the door top (FDT) to the top of each hinge, and measure the lock FDT to the centerline. We have some handy forms with pictures for you to print at the link in this post that will make it easy for you.

Lead Lined doors & frames. Usually you will use a wood door but you can get a lead lined hollow metal door. 1/16" thick lead is "standard" which is 2 pieces of 1/32" lead either side of the wood door core. 1/8" ( 2 pieces 1/16" ) is also used quite often. Common options range from 1/32" to 1/8". Doors will remain 1 3/4" thick with up to 1/8" lead in them. Over that and the door thickness starts to increase so you need a special frame for a non standard thickness door in this case.

DoubleActing.gif Steve in Hollow Metal Doors
The difference between Double Acting doors and Double Egress doors. These 2 terms sometimes cause confusion if you are not in the commercial door industry so let's clear it up! Double acting means the door swings in AND out...versus in OR out for a standard (single acting) door. You'll see this in a lot of restaurants going into the kitchen. This can be a single door or a pair of doors. You'll need a special frame for this application called a Cased Open frame.

A question sent to us by email: Need to install a new frame in an existing wood stud opening that is already drywalled. I can get the frame square and plumb but when I hang the door on the hinge jamb it wants to move. The area is already carpeted and the owner does not want any thresholds so a reverse base anchor is not the answer for securing the jamb. Answer: You would have had to use a knockdown drywall (kd dw) frame as you are going into a stud wall with the drywall already up.
